I have a newly rebuilt 2.9 in my 88 bronco 2 and i cant get any spark.

screwdriver stuck in a plug wire gives a reddish colored spark against a ground but when i try with a plug i get no spark.

i bench tested the coil and it falls in spec can the coil be bad and bench test good?

HELP

 

I would probably start by pulling codes and checking the ICM.

 

> I have a newly rebuilt 2.9 in my 88 bronco 2 and i cant get any spark.

My first assumption would be the timing is off and the dist. is probably on the exhaust stroke and not the compression, 180 degrees off.

 

codes are 22, 122
what do i need to check on the ICM

dist isn't out 180 already checked that before i realized the plugs were not sparking

 

KOEO/CM 22 points to a MAP circuit problem. Doesn't seem like it should be related to a no spark, unless the ICM and MAP wires go through the same harness.

I don't remember the specific steps for testing the ICM, it seems like someone posted them here at one point. Some parts stores will test ICM's in the hopes of selling you a new one.

 

had the ICM tested at the parts store. they said it failed at high rpms.
would this keep it from putting enough power to the plugs to start

i am going to replace it

 

got it the icm changed out along with the cap and rotor. now i have spark but it has a red color
