Question
I have a 1987 Cadillac Allante that is hard starting when cold. cranks more then it should before firing, it is a little hard starting when hot, but is much worse when cold.

Answer
Have your fuel pressure tested to see if you are getting the correct pressure to the engine.

also:

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.
