I need help! I have change the plugs and wires. Replaced the fuel pump. Nothing is working for me. The truck acts like it wants to start but wont. There is no check engine light on. What can I do to make this truck work?

Hello, did you do any testing, before you replaced anything? Can you check fuel pressure? Can you check for codes? Does the mil come on at key on?

Did you try some of the basic tests, spark at the plugs, injector pulse? If you do a lot of cranking during testing and the injectors are pulsing, you may flood it, look at the plugs. If you have that spider fuel system, they are noted for problems.
