New clutch and flywheel in a 91 4.0 5spd AX15 and now it won’t start maybe I’ve got the wrong flywheel but says 91-04 fits?

Does the engine crank?

You have fuel and spark?

Codi Patterson

yes I have spark and fuel. It’ll run now just like crap like it’s out of time, it ran beautifully before I changed clutch

Check the crank sensor, they are commonly damaged if you don't remove them when installing a transmission.

okay the I checked it and looked like the wire was stretched so I ordered one that seemed like the only one I could find and it was on eBay for 15$ and put it on the other day and same thing. So I got a timing gun now I’m guess I’m gonna make sure it’s in time put a new distributor on and plug wires and made sure firing order was right.

Non Mopar crank sensors have been known to be DOA, last a couple feet, a couple miles, days, months, possibly longer. Its a gamble. The older parts are getting hard to find if you want Mopar, so you may be stuck using cheap crank sensors. What brand and part number is the flywheel you put in? Someone here may be able to cross reference it to make sure it really is correct. Parts houses dont always get it right. Doubklecheck any electrical connection you touched to make sure it wasnt damaged in some way putting it back together. Years ago a friend replaced a transmission in an Oldsmobile. Wouldnt start afterwards so they replaced the transmission. Still no start. Ended up being 2 pins in the connector folded over from the last install. Making sure the plug wires are in the right spot is a good idea. And the distributor itself is clocked properly.

Doublecheck everything you did.

Okay I’m gonna double check over everything and I’ll go from there. But I wasn’t positive that the oe cps was bad my throttle body sensor was bad. It was in pieces
