Re: my truck is getting fuel but wont start
Three thing and engine need to crank are fuel fire and compression so if you have the other two then you are losing compression i would suggest running a compression test on it. I hope that helps you out.

I have 1993 chevy 4.3 pickup that about every three years does the same thing it was the fuel pump relay located on passenger side of firewall under a plastic flap. I went to parts store told them my vehicle and got relay took 5 minutes runs fine again Semper Fi!
If you are getting "fire at the plugs", then it is probably a fuel delivery problem. It is very common for the fuel pump to fail in these vehicles, particularly if the truck is run below 1/4 tank of fuel very long. Slide under the truck at the tank and have someone turn on the key. if you don't hear a humming noise then your pump is not running. Check fuses, fuel pump relay, and sending terminals for bad connections. Replace the pump assembly.
What about the fuel filter????? Have you changed it out??? If you can spary something like a started fluid, that means it is a fuel problem. My last check, it has to be above 50-psi on the fuel pressure to make it run right. I had 35psi, but whould not get over 30mph or down hill maybe 45mph. Check both filter & pressure, but check pressure with a New fule filter!!!!
