truck turns over but won't start. It acts like it wants to start but won't.

I can hear the fuel pump when I turn the key to on, after a few moments it stops. After I try to start it I can hear it again until it builds up pressure and stops. I also changed the fuel pump relay. A friend let me borrow his code reader, I will do that soon and should have an answer. Thanks

Pastorbillw, that is not a proper fuel pressure and volume test. The noise that you hear and then stops is not pressure building up. If the engine isn't running after about 3 to 4 seconds the computer stops grounding the fuel pump relay. Unfortunately you or someone will have to hook a fuel pressure tester to the fuel rail and perform the necessary test.

A friend at church told me to to change out the ignition module. So today I changed out the distributor cap, rotor, mag. pickup, and ignition module. Truck started right up! Everything inside the distributor looked bad, that's why I changed them. Thank you Lord it's fixed! Thanks for the input! God bless!
