Does the fuel pump prime?

Is there bright white spark at the plugs?

Any CEL codes?

When you turn the key to ON(II), listen for the low humming sound of the fuel pump priming for 2 seconds in the rear (gas tank). In a quiet place, this priming sound is pretty noticeable.

I check on that..so what if i dont hear nothing..could that be the prob..would i need a new fuel pump then? i did check the fuel line by the fuel pressure r..there was gas that came out when i took off the line just to c if fuel was goin to my injector...

Troubleshooting takes different directions depending on whether the engine lacks only spark, only fuel, or both spark and fuel.

Also check for CEL codes.

If the only problem is the lack of spark, then test the coil and have an auto parts store test the igniter unit in the distributor.
