Well, we know it's a fuel problem because it'll run on the starting fluid. So, when you turn the ignition to the run position, without trying to start it, does the fuel pump run for a few seconds? It should. If it doesn't, do you have power at the fuel pump? If not, what about the fuel pump relay? Have you replaced it? Do you have power there? Any trouble codes stored in the PCM (computer)? Did you replace the fuel filter? Are the fuel, return, and EVAP lines hooked up correctly at the fuel pump? Is the fuel pressure regulator good? How much fuel pressure do you have at the fuel rail? Hope that helps! Jim
