Hi, my name is***** will not be an EIS problem. Low battery voltage or a bad starter motor will cause the starter to disengage after 1/10 of a second. First I would install a new battery. Next I would jump 12V directly to the starter solenoid and see if the starter works. If it does I would remove the starter and lubricate the teeth of the ring gear with a light coating of anti-seize paste. High resistance between the teeth of the starter bendix and the ring gear will cause the problem. The fuel pump does not run on this car unless you are cranking the motor or the motor is running. A bad K40 relay could also cause the problem. If you have not tried a new relay I would suggest that you do so.

Let me know if you have any questions.

Marty
