ok i swapped th computer still nothing and whats the est module and how do you test it

What i meant was the icm ignitition control module. It should be located under your distributor cap. It's should be about 2.5 inches long, black amd have 2 wire plugs going into it. If it voes bad it will cause no spark and your tbi injectors to no squirt. I think they are about $25 at the orielly's by my house. I hope that helps.

This is kind of long winded but it's some good info and it goes over everything step by step.
