The clue is that the car isn't starting.

Now try jumpering the FP and GND terminals of the diagnostic box with the ignition on. If you don't hear the fuel pump, troubleshoot the fuel pump and FP power.

If you do hear the fuel pump, install a fuel pressure gauge (near the oil filter) and do the fuel pressure tests outlined in the factory service manual. Download the FSM from the sticky thread above.

Something else to consider. If it starts every time but then dies like clock work it can be the fuel pump resistor located under the cruse control. This happens becouse the priming system works but when it transitions to computer operation the signle goes dead. You can jump it at the resitor which will give you 12 volts constant. Then replace it.

Take a piece of wire like speaker wire or copper wire strip both ends, touch either end to each point.............. listen for the fuel pump..............

Straighten a paper clip and form it into a U.
