2.3L ('83-'97) Still No Spark

[RustRatz]

I’ve replaced my crankshaft position sensor twice now, replaced both coil packs, DIS module, and a couple other things and still cannot get spark from the coils. Not sure what it is

Any ideas?
Truck is a 92 Ranger 2.3 5 speed XLT

There should be key on power and ground to the ignition module somewhere, I would check that for sure, if that checks out maybe power or ground to the computer or it's mad for some reason...

Only passenger side coil will spark when cranking, so only test for spark on that side, drivers side coil is not activated until RPMs are above 400(cranking speed is 200rpm)

Do 50/50 test just to confirm no spark
Spray fuel into the engine manually
Try to start
If it fires you have spark
If it doesn't fire then you don't, or don't have compression

After cranking the engine pull any spark plug, its tip should be WET with fuel, if so crank sensor is working, if its dry then no crank sensor or spark
If its WET try lighting the tip, should burn easily, if not you have water not gasoline in the system

In 1992 spark is independent from engine computer, it has these 3 parts
Crank sensor
ICM(ignition control module), aka DIS
Coil packs

ICM was a common failure, and its wires and ground
Crank sensors and coil packs tended to work all the time

Tip of the spark plug wouldn’t burn after cranking. Not sure what it is at this point

Was it WET?

 

[RustRatz]

Yep. Very minimal amount though. I think the injectors are slightly clogged.

If spark plugs are WET after cranking it means the Crank Sensor is working and the ICM is passing the crank sensor's timing pulse to the PCM
PCM can't/won't open injectors if there is no timing pulse from crank sensor
