Hey guys, I have a problem I can't solve and I'm hoping someone here can help. Last night I was driving my 2011 GMC Sierra 2WD 5.3L and pulled into a gas station. When I got back in the truck I turned the key to the start position but nothing happened besides the dash going black. I didn't hear the starter click and I didn't hear the fuel pump turn on.
So far here's what I've done:
Tried to jump the car, no success. Took the battery to get tested and it's fine. Switched the relays around to see if something else would quit working and the truck would start, but same outcome. I jumped the two big connectors on the back of the starter and the starter turned over, but the truck never started it actually kept turning even with the power off and didn't stop until I disconnected the battery I replaced the battery in the remote but this didn't fix anything. I thought it might be anti-theft related but the the light on the dash isn't on for the alarm and the truck locks and unlocks with the remote. I connected a scanner to it and am able to see the ecm getting an ignition signal when I turn the key to start Through the scanner I can see that the ECM recognizes that the transmission is in park/neutral Has anyone ran into this before? Is there anything else that would prevent it from starting and cause a no crank, no fuel, no start issue that I need to check? The monitor I'm using has the ability to check basically any sensor value.
So this is my first post on here, been lurking around for a while and have been able to troubleshoot the majority of my problems. But most recently while leaving work truck started up just fine (2001 Silverado 4.3l vortec with 281k miles) and immediately stalled going in reverse tried cranking it and the battery died so I replaced it with a brand new one and it started up just fine and about 5 minutes down the road stalled again and would not start, towed it home and checked for basics fuel and spark, the truck is infact getting fuel even replaced the old fuel filter, the ignition coil has power and is sending power to distributor cap, checked spark plug wires and they aren’t reciving power and grounded a spark plug to check if it wasn’t getting any spark and it has not, replaced both rotor and cap and there is still no spark, all fuses are good, just no power to cap any help is appreciated
Hi, need help please. Hit black ice in my 03 Sierra 2500 with a duramax engine. Went over a 15 foot embankment and came down hard under front driver side corner which pushed everything up several inches. The motor was running when I shut it down but now will not start. I was thinking maybe an emergency fuel shut off was triggered but now i'm thinking maybe something else. Any ideas or help would be truly appreciated.
PS: jumping them isn't as fun as it looks on tv!

So I’ve just bought this truck, and when I try to start it the starter will sometimes stay on after the Motor fires for a few seconds. Then it has a very uneven idle. THEN when I rev the engine it wil rev up then drop down below normal idel and almost stall. This will go away if the truck is warm. Now the only thing I have done since getting it is to pull the pipe off of the purge valve next to the fuel tank because it is broken. I’ve ordered a new purge valve and will install it as soon as it gets in. Is it possible that this is causing some sort of low fuel pressure or something?
Has anyone else has issues like this?
I just bought a 1991 Chevy C70 Kodiak C7H042 6.6L 403 CUI Diesel in amazingly great condition. I am now the 3rd owner of this dump truck. The first owner took great care of the vehicle, everything thing appears to be well maintained and no shade tree work. All the parts, wiring and accessories appear to be original and well maintained. However, the second owner bought this truck and never used it. It has sat in a field for about four years. To get to the point, I completely serviced the truck and replaced the batteries, checked the fuses, grounds, relays and I have absolutely no power to the truck. No interior or exterior lights and no lights on the instrument panel. What could be the issue?
