95 GMC Sierra 5.7L Won't Start/Dies?

Asked by Jun 19, 2014 at 01:31 PM about the 1995 GMC Sierra 1500 C1500 SL Extended Cab LB

Question type: Maintenance & Repair

Hello everyone, I have a 1995 GMC Sierra V8 5.7L that won't start. Ocasionally it will
fire up but it will die fast and even faster if you try to accelerate it. I'm pretty sure it's
misfiring since sometimes you can hear a loud pop out of the exhaust.

I checked the spark plugs and they are getting good spark, blue flame.

Checked the fuel relay and it's good, you can hear the pump. I even used a wire to test
the relay and the pump can be heard but still no luck.

So at this point I'm convinced it's a fuel issue. I changed the fuel filter no change.

To keep it short.
- Engine has Spark
- Fuel Pump Starts
- Changed Fuel Filter
- Truck Dies or won't start but turns

From your post,it sound,s like a bad fuel pump,they will pump and you will here it,but that doe,s not mean it is pushing 45 psi to open your injectors right.Check the fuel pump.
