Cadillac Repair: 2000 Cadillac Escalade wont start, fuel pump relay, cadillac escalade

Question
Hi, My truck will only start if I spray starter fuel in the carburetor.  It will run when it starts but after it's been parked for awhile (overnight), it won't start and I have the same problem.  In addition, the battery keeps wearing down if it's been parked for more than 2 days without being started.  One shop said it was the fuel pump, one said the fuel injector, another said to change the fuel filter or sensor.  We're totally confused because the price of these suggested diagnostics range from $10 - $800.

Answer
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..



let me know.
