crank angle sensor fires the injectors. its in the fsm on how to check them. pull the distributer off but leave the harness connected. turn the shaft on the distributer slowly and listen the injectors they should click one at a time i think.

check that first.

You have to swap ecu...or adjust distributor back 23 degrees

I pulled the cover on the e5 ecu and it was fried...I wish i Pulled it and opened it before i started / started swapping harnesses 4 times!!!

Now with the junk ecu...im not getting any spark and have set the distrib 10 different times...

also I pulled it out and set the wires back on and spun the dis...and could not hear any of the injectors clicking...is the junk ecu finally fried too?
