Have you checked for diagnostic fault codes? What led you to the crank sensor? Which engine do you have? Is the automatic shutdown relay turning on?

Not the add. And I have no communication with my scanner to pcm

2.5 and just a bad guess on the crank sensor

The first thing to check is diagnostic fault codes. Chrysler makes that real easy. Cycle the ignition switch three times from "off" to "run" within five seconds without cranking the engine, then watch the code numbers show up in odometer display.

Next, to check if the ASD relay is turning on, measure the voltage on the dark green / orange wire at the coil pack or any injector. You should see 12 volts there for one second after turning on the ignition switch. What is important is whether that voltage comes back during engine cranking.

If you never see voltage there, suspect a blown fuse in the under-hood fuse box. If you have voltage for one second but not during cranking, you're missing the signal from the camshaft position sensor, the crankshaft position sensor, or both.

Did you notice the mounting hole for the new crank sensor is oblong? There should have been a thick paper spacer stuck to the end to set the critical air gap. Many aftermarket sensors use a thin plastic rib molded to the end for that purpose. If you remove one of those you are to cut off the remaining part of the rib and use a new paper spacer. If you installed a used sensor with no spacer, it likely hit the flex plate and is broken.

Check engine light doesn't illuminate at all. So I can't check codes that way either. My solus pro wont communicate either. I have power and ground to the pcm. And everything else seems to check out. I'm starting to
think the pcm is fried. Yes the crank sensor was new and also had the spacer for the air gap.

For '96 the codes should show up in the odometer display, not with the Check Engine light.

Did you check for voltage on the dark green / orange wire during cranking?
