Need some help with a half ton truck. If you're on here, please let me know.

Thanks.

My sons cheby in havasu was doing same shit, i don’t recall what fix was, but it was semi simple
#nohelp lol
The fuse box under hood can have issues. Where the sub harnesses go into the bottom, those plugs get a little loose. Another thing, if aftermarket crap was added to battery bolt, or loose. Stick a wrench on it and make sure it's snug. The cables have 4 "teeth" that bite the terminal.
Why is it strange? That's a textbook failed connection at the battery terminal.Electrical problem. Totally intermittent...
Truck quit running While Driving!!!
Went totally dead. Like someone had removed the battery.
I was on a video call with the driver, had him pull the cover off the positive terminal, and right when he did that, Everything came back on.
Strange.

There was a period of time when GM failed to strip the insulation off the cables before attaching them to the battery terminal....I've only seen in on the G Vans though. Fix the battery connection.
I would also say look at the battery cables especially if someone recently installed a battery, may have left one cable loose .
Here is the thing...
Even if that was the case, the engine would still run. Why? Cause the alternator is still supplying power.
All the cables are secure.
What Kevin is saying makes the most sense. It almost has to be a main power connector to kill the whole truck like that. Although anything is possible I suppose.
I know there is at least one GM tech on here, but I can't remember who it is!
No, it won't stay running if the circuit is not complete.
Is this a late model car thing?? I never tried it working at the dealership. Always worked on non computer controlled cars.
The main relay will go open if current is interrupted..vehicle dies.
Yea don't ever do it on a computer controlled vehicle...unless you feel like replacing all the control modules after they fry...
Hold this thought for the future:
Pete/Dunefreak on Dumont Dune Riders has been a big help.
Seen it all - done it all with GM trucks and gladly gives advise.

If the brass nut are loose will cause a lot of problems.
Things have changed since I left 16 years ago.View attachment 1114893

Did the whole car go dead or just the inside? did the brake lights work or the headlights work when it died? don’t forget about the ignition switch that gets turned every time he starts the truck, just another thought. Good luck
Now that he said that, it may have been the ignition switch in truck. It was same deal, he got stuck multiple times, last was middle of intersection in havasu Middle of summer, he had to push it solo out of the road. No one jumps out to help when it’s 120 out. Lmao!!The whole truck was dead.

If I recall, he was told battery, replaced. Alternator, he replaced. Connections redone, it just kept happening
I’d call and ask him, but he‘s pouting and unfriended me because he’s a little bitch. lol
I have to ask, are your sure about the ignition switch failure?Now that he said that, it may have been the ignition switch in truck.

Am I sure, nope, but I recall it being something silly.I have to ask, are your sure about the ignition switch failure?
The electrical portion of the switches, since they don't actually handle any real current or load since around 2000's era, are really almost failproof.
The mechanical lock portions, on many vehicles sure, but the electrical switch, never.
Since you seem to be familiar....question about ignition switch in a 2002 Silverado. I replaced the switch when my truck was recovered after the theft a few years ago....OEM unit from the dealer (I had it on the shelf for a year as I suspected it might be going intermitently open causing the trans to default to 2nd gear VERY intermittently...and it appears I might have been right), but now I'm running into a issue where it sticks in the start position sometimes, and doesn't return to "run". I can't remember if the "spring back" mechanism is in the switch itself or in the lock assembly....I'd like to get all the parts on hand before I tear into it.I have to ask, are your sure about the ignition switch failure?

2002 1500HD is old school....still has a throttle cable...very limited BCM functions on this one....which is why I bought it.Ignition switches in the 2000’s could have caused lost voltage problem to the transmission but newer vehicles it is a switched input to the BCM.
