NEED HELP!

[Keiron]

So I put a new 4.0 in my ranger and I’m not getting spark and I’m not sure if I’m getting getting injector pulse either I’m getting 40psi of fuel to the rail and I’ve replaced spark plugs, pcm, and icm and I’m getting power to the plug to the coil pack but no spark out of it anybody have any ideas?

The input for the PCM is from the Crank Sensor, Check to see if it is plugged in and getting voltage. I THINK this sensor gets 12v and sends it on to the PCM as a varying voltage signal as the harmonic balancer passes by. Sensor is just left of the crank.

Best of luck.

There is a spark module behind the passenger's side headlight. Mine was shot after my engine replacement, and i wasnt getting any spark. I forget what the module was called

Edit: its called the ICM and i see you have already replaced it
