1988 Chev Silverado No Start

[@dzdhandzcan816]

🔥 video.....I have an 88 obs - with a 350 I believe I was omw to work yesterday 11/3/23 & it was turning over very strong but would not start... so I’m guessing it’s the Ignition module, control module, map sensor, or fuel pump I pray it’s a cheaper fix $50-$300. I don’t want to just throw parts at it. I don’t like to fix things that aren’t broken as my grandfather would say.

I have weak spark at the spark plugs and my injectors are working fine. I believe i have a bad connection in the rotating magnet mechanism itself.

[@PhillipBailey]

Check the quality of the spark at your coil wire. If its good there is likely a failed cap or rotor. If its weak at the coil try a new coil. Also check the pickup coil connection to the ignition module inside the distributor. These connections had a tendency to corrode although that will usually affect both spark and injector pulse

[@DusterNutbar]

@@PhillipBailey Just waiting for a day when theres not freezing rain to swap one in. Hoping it solves my issue.

[@sumbamotor]

Than You for teaching me something new

[@heakmoney13]

Phil hoping u can help me out. 5.7 TBI crank no start issue. Have installed new plugs wires cap rotor fuel pump and fuel filter. Will crank but no start. Injectors are not priming. If you spray some starting fluid in the throttle body it will turn over and run like a champ. When cranking the injectors aren’t spraying fuel but if you prime it with starter fluid starts right away and the injectors begin function as normal. Lost on the issue

[@PhillipBailey]

You didn't say if you had spark while cranking but since it runs on an alternative fuel source it must have. It would then seem to be fuel related. Have you confirmed actual fuel pressure at the injectors? It could be that the fuel pump is slow to supply fuel and running it longer helps. Connect a noid light across an injector and confirm that the light blinks while cranking. What is odd about your issue is it keeps running once it is started on alternative fuel. I would not recommend starting fluid be used as that is very explosive and can do engine damage. Try carb cleaner or propane. Check the pickup coil wires for corrosion inside the distributor on the ignition module as well. A weak signal may not get converted to a proper reference to the ECM on the purple wire at the distributor. Any codes set? Data parameters in range? MAP reading around 4.7 volts KOEO, Temperature reading correctly, TPS around 0.6volt KOEO. If the TPS is reading WOT (greater than 3.7 volts) the system will be in clear flood mode while cranking and you will have little to no fuel delivery. Try unplugging the TPS. Good luck and keep us posted...

[@PhillipBailey]

What was the problem?

[@heakmoney13]

Hey Phil ended up being Ignition Control Module on the distributor. Had me lost for a few.

@@PhillipBailey hey im having the same problem so at first when i would spray starting fluid it would start but now that i have got a new distributor its a Chinese brand distributor from autozone i had tested the old one its still good should i put the old one in and see if i get spark im getting fuel to the tbi its spraying but no start

[@PhillipBailey]

@@559Obsalex if you have fuel delivery from the injectors then check for spark at the plugs followed br spark at the coil wire. If you have spark at the plugs likely the distributor is not timed correctly. If you have spark at the coil wire going into the distributor but not at the plug wires it could be a faulty rotor. I'd recheck base timing. Take the plug out of number 1 and put your finger into the sparkplug hole. Have a helper bump the starter until you feel compression from the plug hole. Next turn the engine slowly by hand until the timing mark on tge balancer lines up to 0. Remove the distributor cap and make sure the rotor is pointed to number one tower. Also make sure the wires are on in the correct order. 18436572

Hey Phil I got a 87 r10 and just replaced starter, battery, and alternator is good but it just clicks once, no cranks. Being having this problem for awhile it recently died and then randomly started cranking and working for a few days and now it’s dead again. Anything would help thanks

[@PhillipBailey]

Well if the starter just clicks and dies not crank your losing power to the starter. Perform voltage drop tests on the cables. Alternatively you could connect a significant test light to the control side of the starter and see what it does. If it lights and goes out while holding the key in crank then you have a control circuit problem. Safety switch, wiring etc. If it stays lit the measure the voltage on the battery cable at the starter while cranking or at least attempting to crank. Connect the pos volt meter lead to the starter battery bolt and the negative to the starter case. You need a minimum of 10 volts for the stater to work correctly. Check voltage drops on the positive and ground circuits. Good luck

[@swagbucksman34]

I have a 91 gmc it's been sitting for about 2 years I replaced the fuel filter when I first bought it and I tried to drive it today and it turned on and drove for about 30 minutes started to stutter then shut off I went to try to start it and it would crank but wouldn't start I thought it was out of gas but it wasn't

[@PhillipBailey]

That's tough to say. Start by confirming the check engine light comes on with the ignition key and the fuel pump primes. If not check powers and grounds to the ecm. Next check for spark at a plug. Spark should jump 1/2" and be nice blue. If no spark check at the coil wire. If spark present there the problem is inside distributor cap and rotor. No spark check for injectors delivering fuel. Remove the air filter and watch for fuel spray at each injector. No spray you need to check for injector pulse with a noid light. No pulse check distributor pickup inside the cap on the module for corroded connections, check for power at the ignition coil pink or orange wire with key on. Test the pickup coil resistance should be between 500 and 1500ohms. Try a new ignition module. If you have injector pulse, spark but no fuel delivert

[@PhillipBailey]

No fuel delivery need to check fuel pressure. Unfortunately there's no test port. Try spraying some carb cleaner in the throttle body while cranking to see if it starts. If so you might have a failed fuel pump. Hope this helps you.

[@swagbucksman34]

@@PhillipBailey thanks yeah it was weird it seems to have power and all that but I guess it was just burning the fuel that was already in the lines

@3:45 what if that molex connector is all dried and crumbling, can I get just that connector?

[@PhillipBailey]

If you're referring to the white connector at the module inside the cap that is part of the pickup coil. They tended to crumble with age. Clean up the individual terminals, slide some heat shrink onto them, shrink and install the wires. Take note of the polarity as its important. If you really want to change the white connector you have to pull the distributor, disassemble and replace the pickup coil. HTH

@@PhillipBailey Thanks for the quick reply! I followed your advice and it's running fine, but not great. I will check the plug wires tomorrow. It just seems to hesitate once in a while and I heard what seemed like a diesel knock during one of those instances of hesitation. It's only about one time per mile during a 30-mile trip after replacing the module and repairing the wiring. This truck sits a lot as it is my on-farm truck for the last 10 years. Great old truck with just under 101K original miles (and zero rust!).

Ive got a 93 gmc 2 wheel drive 4.3 gas. It was parked since 2019 and drove when parked. Now it not starting. I did check to see if the injectors was pushing fuel out and they wasn't. Im going to check those with a noid light. Its doing what this truck is doing. Im going to check for spark at the coil and the module also. Can it be something else?

[@PhillipBailey]

Need to check spark, fuel pressure, injector pulse etc. I would suspect that the fuel pump has failed from the fuel setting too long in the tank. Do you hear the fuel pump run for a second when you turn on the ignition? It should also run during cranking. Try spraying some carb cleaner into the throttle body and see if it will start briefly.

[@PhillipBailey]

Just saw this. Does the mil turn on with the key and fuel pump prime? Does it have injector pulse at the injectors? Power to the injectors? Will it run if you pour some fuel into the throttle body.

[@whatta7793]

5.7 Vortec, crank no start, fuel pump makes noise, spark at the coil, only 1 spark at the plugs initially when trying to start, replaced entire dist system, crank sensor, ignition control module, sometimes when cranking it will backfire, but through the intake.. clueless on what's next other than possibly the PCM.. any advice?

[@PhillipBailey]

Sounds like your distributor is out of sync. Did you have spark consistently at the plugs while cranking before distributor replacement? Check for a good strong blue spark at the coil wire ging into the distributor . Should jump 3/4" and be blue. If yes remove number 1 plug. Turn the engine over in short bumps feeling for compression stroke in number 1 cylinder. When you get a puff stop and then turn the crank by hand until the timing mark is at 0TDC. remove tge distributor cap and confirm the rotor tip points to number one sparkplug tower. If not remove the distributor and realign it. If it is lined up and you still have weak or no spark at the plugs replace the cap and rotor. Some of the cheap AM caps crossfire internally. I've also seen the rotor with a pinhole in the center and the spark going straight to ground. If you have good spark at the plugs it's possible the timing chain has jumped. Hard to confirm that now that you removed the original distributor. Check fuel pressure and fuel injector delivery. HTH

[@PhillipBailey]

What ended up being the problem?

[@whatta7793]

@@PhillipBailey ended up being the coil.. I was testing it wrong for spark, I was testing the wrong end of the coil and it was sparking, but had a friend check it out and he tested the end that I didn't test, and it wasn't strong enough spark, hardly any spark at all.. changed out the coil and it fired right up. Has new everything else on it now though, lol.

[@TTM719]

I have a 1988 C1500 and sometimes when I try to start it, the starter motor won’t turn over. Then I turn it off, try again and it starts. It has also been making a clicking or metal like noise while I’ve been driving it and I have no clue as to where it’s coming from. Do you have an idea what it is?

[@PhillipBailey]

It's hard to say whats going on there. You need to connect a test light to the S terminal at the starter so you can see if the starter is getting a signal to crank over. If no then check at the neutral safety switch. If yes you likely need a starter. Check battery cables and connections as well. Try moving the shifter when the problem happens. Try tapping on the starter while trying to crank the engine.

[@TTM719]

That may be the problem. But the weird thing about that noise is sometimes it will continue even if the truck is idling. It sounds like a metal clinking noise, but no check engine light comes on while I driving and I've checked inside the engine compartment and haven't seen anything wrong.

[@PhillipBailey]

[@PhillipBailey]

There are lots of reasons for a crank no start. First does the Check Engine light come on with the ignition on. If not check fuses that supply tge ECM. Them power and ground at the ECM. Does the fuel pump prime when you turn the key on? Do you have spark at the plugs, if not check at the coil wire. Do the injectors pulse and deliver fuel. Check fuel pressure. Have to figure out what you are missing...spark, fuel or compression.

Alright dazzle me a fun tale. So I have a 1991 c1500 5L v8 TBI engine. And I bought a 1983 caddy coupdeville with the infamous 8 6 4 4.1l boat anchor. Looking at the two motors they both have the same TBI. What are the odds I can just plop that 5l in that caddy and just adapt a few wires to the correct sensors and this will run?

[@PhillipBailey]

I'm sure the two engines have different bellhousing bolt patterns, torque converter bolt patterns, motor mounts etc. The 8-6-4 ecm won't like the 5L thing set up and I doubt you can simply swap the 5L tbi ecm into the caddy. In short it will be a shit show I'm sure.

[@RusticShine]

@@PhillipBailey caddy uses the same transmission believe it or not.

[@PhillipBailey]

If you are sure the two use the same transmission then it may not be too bad. Still will likely be some programming differences in the transmission controls. I'm not sure if you could just swap ecms but I doubt it. The engine harness will be different for sure. It definitely would not be a simple swap imo and may not be worth the trouble unless you can do all this yourself. Then there's motor mounts, AC mounting, power steering brackets, etc. Good luck.

[@RusticShine]

@@PhillipBailey the 305 has a serpentine belt and all accessorie drives are on the motor v.s a ton of v belts like the 4.1. So power steering shouldn't be an issue, motor mounts I am not certain about yet. But I'll have the motor out Saturday in the caddy and will let cha know.

There is NO Spark, No Coil Spark and No Fuel but I do have a good Pulse to TBI verified with Noid Light. Any hints welcome? Bonus Question 😀: It's a real pain rigging up a Phone to film the Start/Spark Check/Noid Test Process: Does ANYONE KNOW where/if there is a starter relay I can use to bypass ignition switch so I can do test it alone? Or is there another way to safely Bypass Start from under the hood with no relay(if there is not a relay)? Thanks...Confused---😕😕

[@PhillipBailey]

No spark from the coil I'd say check the pink wire at the coil for power with the key on. Does it have an aftermarket tach or wire connected to the white tach wire from the coil? If that shorts out you will have no spark. Connect a test light to the coil white wire and ground. Key on should light steady. Should blink or flicker when cranking. No blinking replace ignition module in distributor. Blinking but no spark replace the coil.

[@PhillipBailey]

This truck does not use a starter relay but if you can get a remote start button on the starter S terminal and positive battery post it will crank and start if the ignition is on. Make sure it's in park or neutral though so you don't kill yourself.

The ECM is not awake if you have no injector pulse, no fuel pump prime and no check engine light. Need to check fuses that supply battery power and ground to the ECM. If they are good check the ECM grounds. If I remember there is a fusible link on one of the insulated feed studs by the fuel pump relay on the right side of the firewall.

Those trucks have a fuel pump relay that is controlled by the ECM. The relay is supposed to run the fuel pump as a prime event for one second at initial key on and then during crank and while running. There is also a backup circuit to run the fuel pump once there's oil pressure. Sounds like the fuel pump relay has failed. It is behind the plastic cover on the right rear of the firewall under the hood. Listen for the relay to click on the off when you turn the ignition on.

I also used these delco ignition setups for 5.7 vortec carbureted marine engine packages I sold a good deal of in previous years. If you have any comments or thoughts on using these delco systems on carbureted GM sbc marine applications im all ears. Keep up the good work. !!

@@anthonyr3928 If you are using the distributor without the EST functionality what are you doing for timing advance? These engines will run with the 4 wire plug on the module unplugged as long as there is fuel delivery ie a carburetor as you mentioned. Problem is you will be stuck with base timing only. Are you using a standalone controller to advance the timing relative to engine speed? Im sure that there is such a thing but have never seen one personally. Alternately you could just advance the timing to the point where it still starts ok but performs better at cruise RPM. Probably around 18 to 20 degrees. Most early marine distributor only incorporated mechanical advance systems as acceleration from a stop and quick throttle changes is not a huge requirement for marine systems imo.

I am having same issue with mine! And like someone else is having to help me out and pay for this shit etc...and I think the mechanic they took it to is a joke!? Like I've had and seen good mechanics and this guy don't seem to know JS!? They told him probably fuel pump!? So he says ya bring it here I'll be glad to look at it fix it! Then he tells me well if it is that I CANT DO THAT!! WELL HELL WHY DIDNT HE TELL THEM THAT B4 THEY TOWED IT HERE!? Then he says it's getting fuel so it ain't that! I suggested Distributer plugs wires etc as it hadn't had that done and was yrs past needing them! So they looked at those and yep they were in horrible condition! So they replaced Dis../cap and plugs! But not the old wires which makes 000 sense to me!!!??? AND rhe coil! But I didn't see them look at or replace this!?

Sorry for your problems but what happened in what order. What is the current problem and what has been done so far...

[@PortDixieandTheJourneyDogs]

@PhillipBailey Thank u!!! We'll after many parts and about 3 days I am finally on the rd again! Turns out he hadn't replaced the distributer!! Just the cap and the plugs...then some other things and finally a fuel filter! And then HE finally replaced the entire distributor and BAM! THAT WAS IT!! He put in a call to a Chevy guy mechanic somewhere!? And that guy told him to do that that they were major issues on my truck or same ones...and that of they were bad they wouldn't let the fuel thru! So the fuel was getting to there but it wouldn't let the fuel get thru esp if the truck got hot! Or once it warmed up! It would just shut it dn! And wouldn't work to let the fuel thru! But them after it would set a little get cold it would let it start that 1 time!? But anyways IT WAS THE DISTRIBUTOR!!! But the parts they did take off still needed it...they were all nasty and full of nasty sludge!! And def would have been an issue at some point!! The DT was like caked in green sludge!! Super bad shape!! FF was full of dirt grime tons of nasty crap to!! Truck runs a TONNN nicer smoother and idles nicely quietly now!! And doesn't drop dn or make noises or cut out or bog dn now! I mean it really sounds nice now and runs and idles super smooth now! So while it was FRUSTRATING AS HELL AND BEYOND TIRING..I MEAN ME AND MY DOGS R JUST WORN THE HELL OUT esp after living on premises for like about 3 days! And being sp couped up! And stressed out! But I KNOWWW THIS HAD TO BE SUPER EXPENSIVE FOR THE 2 ANGELS THAT R DIVIDING THE COST to help some little nobody traveler like me!! And I KNOW GOD WILL BLESS THEM 10 FOLD!!! AND I WILL PRAY FOR THAT EVERY SINGLE DAY!!! I am gonna try get her address so I can at least send some payments to her for them and what they did! I would at least like to make payments to them for a longgg time as I KNOWWW THIS HAS TO BE IN THE 1000S OF DOLLARS!! BUT DEAR GOD AM I BEYOND THANKFUL TO THEM ESP HER AND GOD FOR NOTTT LOSING MY TRUCK MY HOME MY DOGS AND MAYBE EVEN MY LIFE!!! I OWE THEM ALLLL BIG TIME!!! AND THANK U FOR UR TIME AND EFFORT TO CONTACT ME AND TO OFFER ADVICE HELP!!
