Still no fire in the holes
Well I am still working on my 92 commanche project and after replacing the flexplate with the 92. I still can't get it to fire up. Replaced the crank sensor and the cam position sensor reads in good I don't have signal to the replacement coil . Have 12 v but no control sign .? Someone must know where this signal comes from. Been reading service book and u tube , can't seem to find answer. Anyone got a tip? Put a 89 4.0 with 94 tranny and t case plus front diff. All hooked up but still no fire. Looking for a broken wire or? Thanks

Flexplate swap
The truck was 2 wheel drive with a 4.0 in it. Don't know history before I got it. Found a motor from totalled 88-89 with 55.000 mi so I put the motor with the flexplate, distributor and fuel rail from the 92 or what was in the truck. Have new crank position sensor and getting a new cam sensor. Let ya know. Thanks for your help.

Still trying
How do you tell a renix motor from a Chrysler . I see the chrysler stamp on intake from the 92. Definitely different than the one off the 89. Was there a difference in the flexplate from 92 , renix or Chrysler.

If it looks like the first one, that's a ChryCo (h.o.) engine.
If it looks like the second pic, that's a Renix engine. The electrical systems are different between the two.

Which intake gasket did you use? One for the 89 or one for the 94?
I wrote a complete guide on doing this swap from Renix to HO. Click on the link below.
It appears you're going the other way, but you can still see the differences that need to be addressed.

4.0 swap
I looked at the intake that I used from the 92. It looks like a renix style. So I just changed the motor and using the system in the truck with that flexplate. Looks to me like i went from renix motor to a Chrysler motor. Used the new 92 gasket for intake will make sure of fit. Thanks. Reading your swap article to check out why she won't start.

Ok, so we now know you used the 92 flexplate/flywheel with the 92 wiring, that's good news. Now we can start to look at other possibilities.
Did you use the distributor from the 89 engine or the 92?
Sorry for all the detailed questions, we have to ask to help you better figure out the issue. Thanks.

Original distributor that was in engine when I got the truck.
Seems this distributor has been modified as it has been cut at location tab and been indexed. Should I do this with new distributor. It looks right on # 1 plug wire ?
