Reply to Davo/diablo666's Post: Is it the Gray box marked e7zf 17c46 ab 1 3/4" by 2" mounted under the steering column. The reason I ask is that the parts store shows that it looks just like the fuel pump relay.. Thanks
Expert:  Davo replied 11 years ago.
 Do you have a relay center or power distribution box under the hood.That is where it should be located.All relays look similar on most car lines.Look under the hood and let me know if you find it or not.Check and see if you have 12 volts at the inertia switch red wire and at the injectors red wires.You only need to check 1 or 2 injector wires.

Reply to Davo/diablo666's Post: The EEC went into limp mode and needed to be reprogramed.. Thanks
Expert:  Davo replied 11 years ago.

Then you didn't state the facts truthfully.The power to the fuel pump relay doesn't go through the computer.That or the EEC relay fixed the car.Tell me how you programmed the EEC.
