Cadillac Repair: cadilac 2001, fuel pump relay, dash lights

Question
we ran out of gas, after refueling the car still didnt start, is it a bleed air problem to the fuel rail, or reset the inertia cut out switch in the trunk? only 50,000 on car can't be a bad fuel pump car was running fine.

Answer
Cadillac does not use a fuel cut off switch. Most likely you burnt out the pump.

Fuel pump test:

1. Get yourself a helper.

2. remove the gas cap.

3. have one person listen in the gas tank at the gas cap opening.

4. have the other person turn the ignition switch to the ON position ONLY so as the dash lights come on. Do NOT attempt to start the engine.

5. As soon as the ignition key is turned to the ON position, The person at the gas tank should hear the fuel pump run for TWO SECONDS and then it should STOP.

6. Does it ?.


If you do NOT hear it run, in most cases the fault is the fuel pump relay or the fuel pump..
