i have a93 ranger I cannot figure out. It all started with a 224 code that was a failing ICM.one night I parked the truck and it was running however the next morning the truck wouldn't start. I replaced the ICM, CPS and the timing belt (maintenance).using a multi meter I confirmed power to the ICM, CPS. I checked the shared ground wire to ensure everything was grounded properly. While hand turning the crankshaft I checked the signal voltages from the CPS to the ICM, while hand cranking the engine. Output voltage was at 9v for both the CID and CPS signals. I have a weak orange spark on the #2 exhaust Spark plug. I have no spark on the intake side plugs. If I am not mistaken that would be correct,the intake side doesn’t fire till the truck starts? I still have a no run condition and it’s got me at wits end.what am I missing? Maybe the ICM isn’t grounding properly even though I got 12 v when I checked it with a meter from B+ to orange/red ground ICM wire?
