Ok pulled the 15A fuse under hood to keep ECU from dumping fuel during test, Pulled all plugs ran the test, put it all back together, put the fuse back in, now it wont start.

Engine cranks, fuel is being dumped by the injectors, main relay is fine, fuel pump primes, distributor was replaced with known workin one, dizzy is getting 12 volts where it is needed, but she wont fire.

Any ideas?

Testing points to ICM or ECU. I am not throwing any CELs, and the dizzy was working on another car.

I did not reset ECU following the compression test, is there any way this could cause this, cause it ran perfectly fine before the test.

sure you have the right firing order?

 

Yes. Everything is as it should be.

 

If you didn't disconnect the distributor during the compression test most likely you burnt out the ignitor or the coil. Check the coil first the secondary and the primary for resistance.

 

Took me two days to realize I had my firing order wrong.

 

Yeah, the coil tested bad.
