ANOTHER GM Crank No-Start?? (GMC Sierra V6)

[@NVRAMboi]

Thanks Ivan. Kind of refreshing to see a full-sized truck with a basic naturally-aspirated V6 (and a manual). Now *that* is a truck.

[@billziegmond4943]

Ivan knows I am a GM guy. That system was used on a lot GM V6. I kept a spare ICM in a Blazer I owned after getting stranded once when it died. Saved my butt several times. Nice work my friend.

[@_RiseAgainst]

Looks like something I'll need to grab at pull a part to have in my glovebox then.

[@CedroCron]

GM Guy huh, ... Iikes being abused and having your wallet lightened unnecessarily eh?

[@_RiseAgainst]

@@CedroCron GM has made the most consistently reliable vehicles from about 1960 to 2010. I get why people are fans. They have betrayed those fan recently, but what manufacturer hasn't?

[@CedroCron]

@@_RiseAgainst 😂😂😂 Thanks... Needed the laugh. "Consistently reliable vehicles from 1960 to 2010" ... Really. Might want to check actual scores on reliability done by various consumer groups. Then there is the bailouts they needed remember that "too big to fail". Also I can tell you what has rolled through our doors at our shops consistently is broke down GM's, Fords and Chryslers in that order. Same quality problems leading to the same repeated failures over and over again for years upon years in some cases. Don't make me list all the failures GM is known for. I'd be here all year explaining their poor quality in so many areas.

[@_RiseAgainst]

@@CedroCron well I can't argue with your anecdotes and all these consumer reports that span 50 years which you have memorized.

[@pootthatbak2578]

I bet it took at least an hour.😮 Not to mention driving there, making sure he left home with all the right tools, setting up the appointment, dragging out a fuel gauge, an oscilloscope, a laptop, a scanner, untangling the test leads, finding the owners house, checking the oil, reading the codes. Then verifying his own diagnosis by checking wires and pins. Professionals make it look easy

[@adotintheshark4848]

I've a feeling Ivan has seen a few of these in the past.

[@frankcarpenetti5776]

I wish that some other KZbinrs would be as straight to the point as you Ivan! Too much talka- talka just to get to the point. I usually fall asleep half way through their videos. Another great video Ivan, thank you!

[@kevin9c1]

It may be a 2006 but that's a straight up 90s fuel/ignition system. Not saying that's a bad thing.

[@TwisteeTheDefiant1]

Wait till you see the previous video with a 08 Buick running the 3800 using an even older ignition system that dates back to the late 80s. Simple yet effective.

[@jessicav2031]

Yeah, wow, I had no idea they did that so late. The thing looks like it was ripped out of a TBI engine.

[@maxnoe3079]

Yeah. As soon as the video started I said. It needs a control module. That’s basically all that ever went bad on those systems other than the cap and rotor.

[@punkhead4312]

Easy to diagnose.

[@gideonz74b]

As an electronic engineer with literally zero experience with working on cars, I love your videos! There are certainly similarities between your diagnostic work and the debugging work I do on electronic circuits. What I genuinely wonder is why I see so many V6s and V8s in your videos, while the majority of the cars in the road have only 3 or 4 cylinders.

[@craiggoodwin9704]

Ivan, great job diagnosing that truck. Also great to know it is fixed and on the road again. Hope you're enjoying the road trip. Thanks for Sharing! 🙃🙂

[@mikechiodetti4482]

At the City Fleet, we had several of the GM mini vans with the 4.3L V6. They were great except when the intermittents appeared in 2 of the vans. Using my old Fluke Scope, I was able to narrow it down to the Ignition Module like Ivan did here. The intermittents took a lot of time to zero in at the ign module, and the driving did help. The scope had a small "Record" memory, but it worked well. Good one Ivan!

[@CedroCron]

A bad ICM, on a GM? ... No, can't be. LOL ... Good job Ivan!

[@jgeorges3061]

Ivan, Love it brother the way u approach this truck problem even without WIRING diagram JUST BY COMMON SENSE thanks for sharing cheeeers.

[@greystone83]

Ivan fuel Spark run Best diagnose steps in action ,,Thanks

[@windward2818]

I think the ignition amplifier defaults to base timing even without a PCM advance over ride pulse. So, if the amplifier is working the engine should start at base advance.

[@Sandmansa]

That seems to be a fairly common failure item on those engines. I had a customer come in once with an old astro van. Crank, no start. He told me he went to start it and heard a loud explosion. Sure enough, coil and igniter are shot. After I replaced them and got it running, I found out what went boom. The muffler had exploded and ripped wide open. It was the craziest thing I ever saw.

[@joekuntzman4016]

That was a very smooth and efficient diagnosis, great work!

[@donaldnye2890]

[@Peter-pv8xx]

Bought new I have a 97 S10 LS extended cab 4.3 rear wheel drive, in the 26 years I had to replace the water pump alternator battery and tires of course and I rebuilt the front end upper and lower control arms etc. The only trouble I had starting it was when I replaced the cap and rotor with non Delco parts, I used the best of the best from advanced and when it rained and for days after it wouldn't start, thinking there was something wrong with the new components i went back and they gave me new ones under warranty, the same thing happened, I went on the line and did some research and found a guy with the same issue, he replaced the cap and rotor with genuine Delco parts and never had the problem again, i said it couldn't be that simple but it was worth a try, advanced carried the Delco, i replaced it and problem solved.

[@PineHollowAutoDiagnostics]

OEM for the WIN!

[@scrappy7571]

I've seen the pink or the white wires break internally, at the module or coil. Is a common problem with that ignition system.

[@andrewb8548]

I had a code W S-10 Blazer that would stall pulling out of toll booths unless I counted 1,2. It did this from day 1. 60mph+ to complete stop if you went back on the gas in less than 2 seconds stall. They replaced the spider 4 times under warranty. Then 4 other mechanics knowing the history and so sure that would fix the problem didn't get paid. 8 spiders from the lot to the junkyard. 160k NEVER RAN RIGHT.

[@zeropointenergy1574]

Awesome combination - Ivan and an oscilloscope.

[@steveb6371]

My Astro had two problems in its 280000 miles. One, fuel pump at 147000 miles and ignition module at 205000 miles. Amazing how certain technologies fail at about the same time.

[@farmermiyagi1338]

I have an 1994 S10 blazer with the 4.3 first gen. I can't remember off top of my head if that's the X or W 4.3 code. The ground on the ICM was crappy and it kept eating modules. Mine is under the cap though. Moved the ground and haven't had to replace one since. ;)

[@chrishill1219]

Very good Ivan. This again proves as you keep saying, you need to know how the system works and of course homework and wiring diagrams. May I ask, will you ever do a fix on anti collision Lidar.

[@biondanishgenomeinstitute8193]

Whenever its a module, you usually replace it. Isn't it often something simple inside that can be repaired, or do they degrade beyond repair?

[@brianw8963]

There is no opening up those little ignition modules on these, just toss and replace. Pretty common failure on this style.

[@normyanke2515]

usually they are potted or coated, at least in the engine compartment, my jeep heater control panel lights went out, something like $100 for module, I replaced the light, had it in my junk box.

[@pootthatbak2578]

Modules like this are often " potted" meaning the circuit is built and tested ok, then a resin is poured over the electronic parts to help resist moisture and vibration- induced failures. The unit is then permanently sealed. Digging potting off components is very difficult. So no, component repair is unlikely

CPI leaky fuel rail "spider assy" was fixed by 1998, surely by 2006. I had a 1995 blazer S10 4.3 Liter vortec V6 that i gave up on because we had to lift the intake up once a year to install a new fuel rail. our ignition module died too. I put a non-ACdelco after market module in. I gave up and finally gave it to my mechanic, had to tow it there..BOY OH BOY!! i will never forget the tongue lashing that salty old Navy Veteran mechanic gave to me for putting the cheap ignition module in.😅

It seems that Holden did away with an engine which is that old in 2004 which is the 3.8 litre Buick L36 V6 engine. I know that the engine in the video is a Chevy V6 & not a Buick but in Australia they were using the 3.6 litre litre GM global V6 engine 20 years ago. GM were still using the Buick L36 V6 engine up until 2008 in the U.S., Holden stopped fitting those old engines for emission control reasons in Australia. It's like in New Zealand they ceased manufacturing leaded fuelled vehicles in 1996 which was a decade after in Australia they made it mandatory for every brand new vehicle to be made to run on unleaded fuel !

[@BillMalcolm-tn3kq]

GM took a while to shovel the High Feature V6 into Colorados and Canyons, I think. Cost a fortune to make compared to this pushrod donkey 4.3 l 90 degree V6. Why they made both this thing and the Buick 3800 for years is beyond my ken. GM is beyond my ken. The GM board let that idiot Wagoner lose $70 billion in stock value between 1999 and 2007. Then flat out bankruptcy happened. Anyone ever heard what became of the man who blew GM to smithereens? As for what happened in Australia and NZ that nobody cares about, sorry, here's another now useless factoid. The EU didn't fully have unleaded fuel availability and cats and a set of pollution regulations until 1992. 1975 in North America. Of course, to listen to Europeans, you'd think they invented all the green stuff, because they have marvelous selected memories.
