Was driving then all the sudden truck quit.it will turn over but wont start.acts like it isnt getting gas.i can hear fuel pump running.replaced fuel filter,spark plugs,and distributer.still cant get it to start. Any ideas?

Check for a bad distributor cap and or rotor..........a bad cap and or rotor can caues firing (cross fire)across the terminals and introduce spark to the wrong cylinders at the wrong time.......
hope this helps.....good luck!

the fuel pump could actually be malfunctioning. and the reason that you are able to restart and drive again is because when you turn the key on it is allowing the fuel pump to pressureize your system. but while the fuel pump is continuasly running it is loosing the fuel pressure. this is common on the cheap fuel pumps. i am not sure about were you got the fuel pump from but in all of my experiances with this problem i find that the fuel pumps have been boughten at a napa store.
i hope this helps you out.
and you could attach a fuel pressure gauge on to the fuel rail and start the car and watch the pressure to see if it is droping.

It sounds like you have a security problem, I had the same thing it would fire and run for half of a second and then that was it if anything at all. Had the security system rebooted, now it starts and runs fine.

your statement is "my jimmy won't turn over"
why are you concerned about the fuel pump?
the fuel pump only supplys fuel to the injectors while the engine is cranking over & runing. You should be looking at a dead battery or faulty starter. Its also possible the engine is locked up. But I would start by trying to jump the battery. If the starter is starting to fail, sometimes you can use a small hammer and lightly hit the starter while someone else is turning the key, this method can be dangerous to the person under the car so be carfull, but it can cause the starter to rotate enough to catch and crank the engine over properly.
If your concern is that the engine is cranking over & wont start, that a different issue.
Your truck does not have a fuel shut off like some Ford products. You can simply depress the shreader valve in the fuel line while the key is on & you should get a lot of fuel to spray out. This would indicate the pump is working and the problem maybe electrical, no spark.
