And I do have 5volts at map, CPS, tps and cam sensor and O2 sensors.

I still have no spark or injector pulse.

This is where I get lost, I thought that wire was supposed to be 12 volt hot, pin 7?

Coil tests good, no 12 volt signal from no.7 pin on ecm.

Another update, we replace the computer, right away our check engine light came back, fuel pump is working, we are getting 5.5 volts to CPS, and cam sensor, we didn’t have this before. Went ahead and changed out the CPS anyway just to rule it out. Still not getting any voltage to coil, we are...

Everything was unplugged when we purchased the Jeep, no check engine light and would not give us any codes. The one thing we didn’t do was check for 5 volts while everything was unplugged. We will do that next.

Update, checking voltage on pcm, we have 12 volts at pin 22, we have ground at pin 31 and 32 but we are not getting 5 volts out on pin 17 black connector and pin 31 white connector.
