Sounds like your Passlock security system went into the tamper mode. If your dashboard security light blinks when the ignition is turned on, your Passlock security system is disabling the injector module, preventing the car from start. Try this:
1- turn the ignition on and just touch the starter, without getting the motor to fire, then leave the ignition in the "on" position. The security light will blink for about 10 minutes. When the light stops blinking, turn the ignition off and leave off for 3 minutes.
2-repeat the step #1, 3 or 4 times. You will know that is fixed when you turn the ignition on and the security light does not blink, then the car will start. Make sure to stay inside the car when you're doing this, as opening the doors will trip the security tamper mode on again. Once the tamper mode is off, the car starts and opening the doors will not trip the Passlock tamper mode.

SOURCE: fuel pump relay location

There may be a fuel pump fuse or connection you can undo but the relay is integrated with the entire injection system. If you disconnect it, you will lose spark as well. I would look through the fuse box first, I will drag out my wiring diagram in the morning and give you more specific details.

SOURCE: which relay is the fuel pump relay?

Can't find my picture right now, but look for a relay with following wires in connector. Dark blue/w yellow stripe, dark blue, dark green w/black stripe, & red w/white stripe. that should be it.

Where is fuel pump fuse


Hi there,

Well there's no fuel pump fuse only a fuel pump relay. Chances are if the fuel pump doesn't activate it is an internal problem and the fuel pump relay is located under the hood. Post comments for further help or information......

Thanks

Replace the FUEL PUMP RELAY. Its located in the under hood relay center. This relay primes the pump with the key on, about 2 seconds, then the pump will not run until the engine has oil pressure, then the fuel pump is energized.
