I am not getting any fire at all. I came hone from work shut it off and went back out and it wouldn't start. Its cranking but just won't start. Bought a tester and its getting no fire. Had the ignition control module tested and it was good! What would be the next thing to check?

Check the crank sensor and make sure you are getting power to the coil.

Not equipped with crank sensor! The coil is good and the rotor is new. Still no fire at all? What should be next step?

The coil is new. I took the module to auto zone and they hooked it up to a machine and it tested good! I don't know what else to check!

If you have power to the coil and the module is good, you should have spark. I hate to say it, but I feel the module is the problem. Are you able to get your hands on a different one that is known to be good just to try it?

I went through problems with a DIC a week ago. I had A Z test it and they said it was good. However, I was only getting spark to one bank of the engine. Switched the DIC and it ran perfect. I have to question some of their test equipment. Please keep in mind, I know I may be wrong, but I would try it.

What do you mean dic? What are you referring to? And do you think that the distributor could be bad?

DIC is a digital ignition control module which you don't have. I was just trying to make a comparison. As far as the distributor, it could be bad, but I doubt it.
