If it cranks good, but won't start, have a helper crank it while you visually check for spark at the plugs. If you have spark everywhere, use a gage and check fuel pressure. Any applicable mil codes?

well i believe its somethin to do with the fuel pump because before when you turned the key you could hear the fuel pump turn on and now you dont hear anything. im not sure if it could be a loose wire to the fuel pump or maybe some security issue with the computer shutting it off. not sure what to check for.

If you want to check for voltage and ground at the fuel pump connector, engine cranking, that will work. Let us know what you find.

To check for codes, you turn the key till the dash lites come on, no further, cycle key on--off, on--off, on, then the mil starts flashing, you count the flashes to get the codes. Your looking for two digit codes.
