OK here is tha deal i have a lancer 2002 OZ tha is not getting spark (juice) on piston 3-4 (diagram shows piston order timing bel side is 1-3-4-2) i did replace that ignition coils then i check for any electric issues on the hardness and find that ignition coil connector for 3-4 piston dont send electric current color green/black cable. i did check the other ignition coil connector and that one works blink and get current normal . my question is where u thing is the problem?

The ECU directly controls the primary signal to the ignition coils. Check for broken wires in the harness. Failure of the ECU itself would be extremely rare but nevertheless possible.

ok so i remove the engine control unit and test the wiring between the ECU and the #2 / 3# ignition coil (wire test out ok) test for the ignition signal pulse at ECU .found wire at ECU 1#/ 4#coil pulsing power(switching)but the ECU wire 2#/3# ignition coil no pulsing power!....
ECU NUMBER IS MR578519

If a replace the ECU for a used one or refurnish one do i need to look for any ECU that HAS the same ECU NUMBER MR578519 (Matter if is a different car model ?)and if so has to be the same car and model (Mitsubishi lancer OZ 2002) If anyone knows where can i get one for cheap i am not looking to spend a big money on this i just need the car running (car has no upgrade or anything )thank you for u help . u can PM

Hey Mitsu-

You say you replaced the ignition coils, but did you also replace them with stock OEM coils? Stock coils already have too weak of a spark to be able to handle the pressure on performance cars, in most cases.

You might want to look into these coils : Plasma Direct coils. They're performance igntion coils, high quality, made in Japan. They give you four times the spark of normal coils, plus more power overall.

I know you can look up some of the dealers, but they are sold by Plasma Projects here in Europe. I know one of their dealers here in Germany, and he has a lot of good things to say on the coils.

This is to their website: https://shop.plasmaprojects.com/product_info/2/Plasma_Direct.html

Hope this bit helps!

I had the damnest problem with my coils, completely replace and get the correct spark plugs and you should be fine. Mine ate two sets right away due to wrong spark plugs. Good luck man! Hope everything works out well.
