Cadillac Repair: 1996 theft warning, defective alternator, fuel pump relay

Question
I changed out a defective alternator. The car cranks but will not start. The dash reads anti theft is invoked. The manual shows how to reset by the system of 3 minutes then 2 then 1 then restart. I have sprayed ether in the air intake to see if spark is there and there is. It trys to start but once the ether is gone, it just cranks.Have I cleared the wrong thing when I cleared the codes with the off and heat causing this and how do I correct this.

Answer
This would indicate that you are NOT getting any fuel to the engine.

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.
