chevy s10 gmc sonoma 4.3L cranking no start

[@actionjackson64]

Truck cut off 1/4 mile from work in the snow. Checked the ignition coil. No spark. Went to the fuse box. Blown 15A fuse off the relay. Worked a full day and made it home with no problem. Thanks. This video was key to troubleshooting.

[@mikeb4675]

Hands down one of, if not best video I have seen. It was informative, enjoyable, easy to comprehend. For a minute or so, actually thought I was right there hands on training. Thank you, look forward to checking out other videos..

Why didn't I watch this video 2 WEEKS ago???!!! I checked for spark and fuel but didn't think of distributor. Same symptoms so I am about to check that. I immediately subscribed and liked video. Thanks man!!!

[@manuelester7420]

I bought $300 worth of electrical parts only to find is actually was my distributor which i installed incorrectly. Then yesterday i re installed it and hit the jackpot. The timing has never been more smooth. My engine went from sounding like a dying moped, to a quiet running van. 😂🎉 Im so happy i got my van back.

[@peterlynch8768]

Thank you, sitting in my truck and the same situation and you showed me my problem. Very much appreciated

[@jerk151]

Thank you so much. The jumping over the starter relay was a huge help to me as I was working on it by myself. May be common knowledge for some, but I did not know it. I knew I had power and getting fuel, was pondering about checking for spark. I have this engine in a 1500 silverado. Turned out my d-cap cracked under one of the two screws and let in moisture. All posts were corroded and button burned out.

[@jerk151]

Unfortunately, 2 days later I am right back where I was.

[@SteveKirby-r2k]

I already did cap and button and coil and coil wire and fuel pump but still won't start. Getting fire at coil and getting gas. What's wrong? It died going down road

[@gemanscombe4985]

@7:30. Orange spark is weak and coil may be failing. Blue spark is strong and coil is okay. Color shows temperature of ionized air of the spark gap. Blue is hot, orange or yellow less hot. @9:48, rat droppings on distributor cap can mean chewed wires. Rotors have asymmetrical mounting lugs underneath to prevent installing 180* off.

[@mr.review9101]

Great video! I have a 97 blazer with the 4.3. It does the same thing as this was doing however it normally will fire off starting fluid. I haven't tested fuel pressure yet. But once I test pressure how do you determine if it's the injectors or the pump that would be bad?

[@dilloncalvert4584]

This is what I need the answer too as well!

[@HardCoreGarage]

The s10 is a great all around truck!

[@Jamie-o5h]

You did great job explaining it. Hope that's my problem also

[@learvette]

Hi, my 99 s-10 p/up 4.3 is doing the same thing. I checked to see if it was getting fuel thats ok, then I removed the spark plug wire from the coil and lots of spark even from pretty high above the coil and put the spark plug wire back on and the truck started right up. I played with the wires all around the coil to see if I could get some kind of reaction from the engine but it ran smooth as always. I am now worrying about it happening again at a bad time and get stuck somewhere. PS, I changed the coil,wires,cap& rotor and pvc valve. Cleaned M.A.F & throttle bodie & new fuel filter all at 5000 mile ago.

[@naruttaanime9471]

Add on idea:for car owner diy'ers: check some spark plugs if badly worn, then also replace spark plug wires with as well. Put dab dielectric grease on each plug boot. This is the extra care the dearlership mechanics do when working on thir own cars. (Mo commisioned service mgr breathing down their neck to maximize profit by rushing the tech , while still overcharging the poor customer). Parking brake on will avoid daytime lights going on and help recharge that nearly dead battery.

By chance was it backfiring and not starting? Mine i replaced everything bur the crankshaft sensor and it won't start and backfires out the intake and exhaust so ima replace the crankshaft sensor

[@hunterporter8831]

I am having this same problem. I will let you know if these trouble shooting methods help me fix it.

[@corey6393]

@7:30 you have the spark colors swapped. Blue/white spark is a sign of much better and hotter spark than orange or yellow. Great diagnosis video. Helping a neighbor swap a fuel pump in his S10 next weekend and been watching some basic diag videos just for a refresh of the process.

[@Mike_The_Hog_A_Nator]

Have an 02' Blazer ZR2 & drove it to the store & got back in & nothing! It would Crank but not start. Luckily I took it to a Mechanic that knew about 4.3's & he checked the ECM & Coil. He found that it was cracked immediately & replaced it & I was on my way..

[@John-se1vn]

Great video! Thanks for your help. Very helpful

[@malcolmbourque4381]

I have watched several videos on 4.3 no start and have seen different ways to check for spark. Does nobody own a timing light anymore?

[@TravisJenson-zv9lz]

Timing lights are cool and what not but pulling a boot off of a spark plug, remove spark p. Plug spark p back in boot , rest electrode against exhaust manifold, turn ignition sticks , if you dont see spark there , start backtracking …same ol shit, different century.

How would I know if it might be a battery? My wife drove home last night no problem and then went to drive again to goto the gas station and it wouldn’t start. Acted like the battery was low. I tried starting it today. I can hear the fuel pump priming. I hooked up a jumper battery but it still wouldn’t start and basically drained the battery. Should I take the battery to autozone and get it tested first? I’m wondering if a bad battery would cause the symptoms. If it was alternator, it should have at least jumped off

[@crack1666]

I've never had to deal with it on my Chevy, but a coworker had that issue, there is a switch under the pedal (or somewhere nearby) that when pushed in, it completes the circuit and allows the brake lights to power on, when released it closes the circuit so that the lights turn off. Turned out her switch was old and stuck open whether pressure to the pedal was applied or not. Was easy to replace and did the trick. I imagine you have the same issue

My cap and rotor look fine though? There cheap so maybe I’ll just throw one on there too see

What do you do if you put a new crank shaft sensor, cam shaft sensor, cap and rotor on and it’s still cranking but won’t start

[@k24oreo84]

Coil pack is the main source of apart and multiplies it in the distributor.

[@curtischung1009]

Might have to perform a relearn. A lot of times the sensors you buy are honestly bunk cheaply made ones and there junk out the box. If you ohm test the sensor and you have power ground and a signal to the connector. If that don’t work I’d recommend looking into the PCM.

[@manuelester7420]

⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️😀Take high heat silicone and mix it in a spray bottle with alcohol to thin it out so its sprayable. Then cover up all metal points and the middle button with masking tape and then spray the entire cap, inside and out and let it dry. Remove tape while still wet. Your distributor cap will be coated with rubber like a glove and the cap is not insulated and water proof. The silicone will cover the micro cracks and any pours in the plastic of the cap. Preventing arching. Also preventing corrosion from outside moisture. I bet it would last way longer. 😎 Try it.

I did that to my entire coil. I covered it in silicon all over, except for its electrical connections.

So what do i do with my 89 4.3: we've lastly replaced ecm (AC Delco), won't idle less than about 1500 - 2000 RPM now. Accelerating it acts like there's no advance. Before all of that, replaced the dist, module 2X. Coil, Cap & rotor, ABS module, Coolant temp sensor & throttle position sensor. The cause, because it'd go dead on the road. Besides running rough n Popping back through intake. With each part change it'd briefly run ok then go dead again. With this new ecm starting up it doesn't go into high idle and reduce to proper idle. Just runs up n stays there even while test driving it. Any thing you might suggest? I'm lost.
