#125 of 138 1995 gmc sierra problem
Sep 26, 2012 (11:09 am)
Hey I got a 1995 gmc sierra 5.7l v8 z71 with 450,000k and well this problem first started after i drove for about 25minutes or + then parked for 5 minutes and restarted my engine almost immediately after started its like it stalls. The battery volts go down oil pressure goes down and it vibrates and shuts off. happened alot during the summer and then stopped for a month now even sometimes when im driving alot even in a parking lot the same thing happens im accelerating and then its like it looses power and battery volts go down as well as the oil pressure and dies but i can start it right away. and sometimes when its doing this if i accelerate alot harder it won't die. For winter i need tires rear brakes and my power steering pump is leaking so before i start putting money into this i need to fix this issue. Any thought or potential solutions would be greatly appreciated.

I'm not sure if you have fixed your problem yet, but I would try the remote battery terminal. Loosen the bolts and hit all the contacts with a piece of sandpaper or steel wool or something. After years corrosion builds up and doesn't break the connection, but can weaken the flow of current. Like I said, I'm not sure if it helps all, but I've had several vehicles that had that problem and that is what it was. I hope it helps.

i tried that last week and it is still happening, however when the truck shuts off my battery light and my check gages light comes on so does that mean all this is my battery? cause when im driving and accelerate and it sputters it doesnt shut off then so is that a different problem?

Truck battery died tried to jump it. Didn't work. New battery starts fine,runs fine but lights dim at stops. Truck idles down and wants to stall. Hit the gas back to normal. Alternator tested good, ground looked good, checked blower motor resistor looked fine, and blower works fine. Also truck stays running if heater is off at low RPM's. Any comments could help

I have a 2003 silverado 4.3L that I have an issue with when I try to accelerate. I turn the truck on and it turns on perfectly fine, when I put it in gear and try to take off it stalls like if gas was being restricted, this is only when i have it in drive! I can drive it but it will stall literally every other second and i've noticed that when it blows black smoke. It doesnt give me any check engine light, put a scanner in and no codes....I have replaced fuel pressure regulator, fuel pump, fuel injectors and fuel filter and not it does this...any help will be appreciated.

#133 of 138 engine stalling after about 30 minutes
Mar 09, 2013 (10:55 am)
I have a '95 k2500 silverado 6.5 turbo diesel 4x4 with around 250,000+ miles on it. The beginning of February I drove it one morning and everything was fine. left for home in the evening still fine. Stopped to do something then went to turn it on (belched black smoke) and it stalled almost immediately. This happened several times in a row. Waited on a mechanic to show up and by the time he got there it started up and ran fine. Got almost home and it stalled out again. Next day this happened again and it stalled out while I was driving this time. Started it up just fine but no smoke this time. Its now the middle of March and I just got the money up to replace the lift pump drive (been sitting since February). Put it on last night, drove it today and still after 30 minutes the truck wants to die. Last year I had to replace the fuel pump 2-3 times. If I replace it again will this solve the issue? I'm at the limit of what I know to do. Does anyone have any suggestions please?

Black smoke means the engine is getting more fuel than it can handle (diesel tuners used to pride themselves on how much black smoke they could generate with fueling boxes). It almost sounds like your stalling is due to fuel flooding. You'll probably need to mount a fuel pressure gauge and check to see if you're in spec - it could also be your fuel pressure regulator that's failing.
