My truck won't stay running, it will start for a few seconds but never
reachs an idle. It acts like it's not getting fuel. There were no
signs of trouble until it just died. What should I check first? Fuel
pump, fuel filter, is there anything else I should check?
It's a gas engine, I was able to get it started by pouring a bit of
gas in the throttle body. Then it dies when the fuel is gone. I
swapped out the fuel relay, no help. Is there a way to check the fuel
pump when cranking the engine?
In responce to dluns 's post. I thought everyone should know:
with a cheap fuel pressure gauge from sears you can check fuel pressure at
the fuel rail. there should be a fitting that looks kinda like the top to
a valve stem on your tire, on the fuel rail next to the intake (between
the intake and valve covers.) connect the fuel pressure gauge and then
turn the key on, look at the gauge if you see 49 psi +/- 2 psi according
to the 03 service manual, its the same gas engine so i would imagine that
number is close. if you do not see fuel adequate pressure after cycling
the key on and while cranking then i would suspect something wrong with
the fuel pump module or the wiring going to the fuel pump. i have seen
dogs and other animals get under a truck and have a field day eating any
wire harness they can get a hold of.
