I need a little help here. I purchased an 86 Ranger not to long ago. Ran fine for about a week then I notice it would miss every once and a while when Idling whether hot or cold resulting in a little engine rock. Then about two weeks after this started I was coasting down the ally behind my house when I went through a puddle and hit a pot hole that was hidden by the puddle. About three seconds later the engine just died outright, no sputtering or ruff idle nothing just stopped firing like I had turned it off. Now I can't get her to fire no mater what I try, and I've tried a lot.
I've checked for fuel pressure. OK
Injectors are Firing.
No Spark at Plugs when turned over.
No Spark at Coil when turned over.
12V on both sides of Coil with key on.
Coil Resistances are good.
Harness rings out good from coil to ICM.
And today I pulled the ICM off the distributor and measured the resistances as per the diagnostics page. All resistances are slightly higher/lower than what is listed as Min/Max. The only thing that Didn't ring out was the backplate to any terminal, (not sure if it is only for heat sinking purposes or to provide grounding), reads as an open.
I'm pretty sure it's the ICM but I'm not sure as the one I got at the reckers is ringing out almost identically to the old one. Any help you can give will be greatly appreciated.
