Download a Factory Service Manual here from Zilvia.Net. Use the SEARCH feature.
Once you've downloaded the factory service manual for your model year car, locate both the ECU relay & fuel pump relay and replace them both with NEW OEM factory relays.
Also pull your steering column cover off & using a continuity tester, ohm meter, or volt meter, test your ignition switch to make sure it is working properly.
Also check your main wiring harness from the ECU to the motor by wiggling it as the motor is running. You want to make sure there are no shorts in the harness between the ECU and the point where the harness runs next to the fuel injectors. CAREFULLY try to wiggle the wires that lead to the distributor at the front of the engine - don't let the spinning plastic radiator fans wack your fingers as you test the wires running at the front of the engine to the distributor. You want to be sure you don't have any shorts in the harness there also. Also check the wires running to your MAF...make sure there are no shorts in those wires either.
And finally, check all your ground points at the ECU, ECI & fuel pump relays, and the engine ground relay on the driver side engine block by the fireway above the 02 sensor. Make sure there are NO shorts at those points.
Tracing electrical gremlins are a bitch.....hope this helps...
