Answer
Are you sure you are getting spark to the spark plugs ?. Check it.

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 ?.

7. If it does NOT run for the 2 seconds the fault is either the fuel pump or the fuel pump relay.

8. You need to put a fuel pump gage on the fuel line to be sure your getting sufficient pressure.


CAUTION: Being EXTREMLY careful put a small amount of gas in the intake manifold and see if the car tries to start.

let me kniow.
