1990 Mighty Max 2.4l
Developed rough idle and then hard to start. Problem then led to no start. After tons if reading and asking I was told to check ecu for bad caps. Found two that looked burned nd leaking so I (not a pro solderer) thought I fixed but was to no avail. Sent ecu to rebuild company and was said it was repaired and it had a secondary hardware failure. Still no start.
A lot of reading and testing and this is what I have - No spark from coil to plugs. 12v at both coil wires with spec ohms to primary and secondary but no ground pulse (gp).
12v on 1 0v on ign. control module but no gp. Distributor is putting out 12v. 2@4.96v and a ground with both 4.96v showing gp. Also, white line, pin #4 from ecu has no signal that I can detect.
My understanding is signal from dist. goes to ecu that sends gp to ign. control and travels to coil to create spark.
Would this mean the ecu is bad (?)and I need to return for repair since it comes with life time.
Sorry for the long wind and I am sure confusing way to ask question.
Thanks
