Answer
Yes, the electric fuel pump is in the fuel tank.


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. usually if you crank the engine for 2 or 3 minutes it will build up enough oil pressure to run the fuel pump and start the car. This would indicate a fuel pump relay failure.



let me know.
