I recently bought a 90 eclipse gs 2.0l dohc non turbo that had no spark, the guy said he took it to a shop and they told him it was the crank angle sensor.. so i replaced that still no spark.. all fuses good, coil packs have power, ground and continuity, power transistor tested good for continuity,but still no spark at the coil? was told on alldata to test ecu connector wire 109 and ground for continuity, says continuity should not exist, and it did exist? where the hell is my problem? i dont feel that ripping into the computer is the right thing, i feel its something small, everything test good for power ground and continuity?? Some one please help.

 

Check for an injector pulse and pull the ecu out and inspect the circuit board.

 

k so i tried to check for injector pulse today with a voltage meter. it read 5 thousandths of a volt when i turned the car over? bad ecu?

 

The best way is to use a test light, I sent you a pm w/ my email address. Send me pics of the ecu.
