Question about Cars & Trucks
There are a variety of problems that could cause that, but if you mash the accelerator and it dies, you may want to put a fuel pressure gauge on the fuel rail to measure your fuel pressure. Assuming you have the V8 350 in it, that engine can require upwards of 30psi at the rail, and even a few pounds less can cause it to stall. You may have a dying fuel pump or clogged filter. That's where I would start, hopefully this helps!

Possible weak spark from ignition coil or low fuel pressure due to weak pump. Try spraying carb clean into intake throttle body when problem is present. If vehicle will start and run with a little spray then fuel pump is failing.

SOURCE: idles to fast
When I crank my truck it runs wide open for a minute of so and then it starts to idle down. What causes this? It is a 1992 Chevy S10 v6 pickup. How can I fix this problem? I have no manuel on this vehicle for a diagram of the engine at all.
Thank you. Dave

If your idle is going from 500rpms to 1000rpm's fluctuating at and idle your EGR valve is probably carbon up and needs cleaned or replace.

I put a new fuel pump, fuel filter, and a fuel pump relay and the fuel pump is still not coming on. I am not getting any fuel. Can you please tell me what it might be.

the problem you are discribing would lead me to belive your fuel filter is clogged which is a simple fix 3 dollar part at any part store or on the worse hand your fuel pump itself could be weak you can open the gas tank cover and have another person turn the truck key to the on position without going far enough to start you will hear a faint whining noise if it is going bad or a louder noise if it is fine Good Luck
