No Spark on cyl 1, 4

[easa_13]

Hello need help with my eclipse i don't have spark on cyl 1, 4 same coil, i did some testing : transistor unit OK i intercepted the ecu signal and connected it with a direct positite and i got spark on all coils transistor ok . Coil Pack, OK . Cam sensor signal OK . Crank sensor signal l OK. but the ecu is not sending a positive signal to the transistor for the cyl 1, 4 and for cyl 2 3 i have bliking positive signal form the ECU and nothig for the 1 4. could be My ECU??? or there is something else that can be bad

HELP i love y car but it does not start

It sounds like you're on the right track with the diagnosis. It sounds like the ecu to me.

Yeah it sounds like your ecu might need to be replaced, or serviced.

i just got the ecmlink hooked up and i was able to control the cars fans fuels and stuff so im sure its working, i even swapped my oem ecu and it didnt make a difference but im leaning towards the CAS
