Welcome to the Forum jenjen75.jy

From what I understand, it should. You may have to put a jumper in the plug in your engine wire harness that would run down to the neutral safety switch if you had an automatic. Somewhere near the back of your motor look for an unused plug. It may have three terminals, but only two wires. Your '95 is different than my '89 so the neutral safety plug may be entirely different.

Good Luck, L.M.

 

I went from a 5spd manual to a Cherokee 4spd auto and no change to the ECU. I even used my original crank position sensor when I swapped. Currently running a Cherokee XJ ECU without any issues. YMMV

 

the ecu came out of an automatic and my wranglers a 5 speed. It will start but dies immediately.

 

What was wrong with the original ECU?

 

Somebody stole the original one off the jeep

 

Here's a link to several Factory Service Manuals, thanks to Got it at last. Click on the link and then click on the FSM that's for your year YJ. Go to the 4.0 engine section and look for a diagnostic flowchart.

Other members with FI motors will hopefully chime in with suggestions. The more information you provide as far as your Wrangler and what you've done to cure your issue, the better the suggestions you should receive.

Good Luck, L.M.

thank you

 

we have already put the ecm that came out of the 95 cherokee 4.0 on the 95 wrangler 4.0. Now it will not start up unless gas is poured in the breather. it'll run for a minute or two then acts like it runs out of gas and dies.

 

I would think you just ruled out the ECM as your problem. Sounds like you have a fuel delivery issue. When you first turn the key to the on position and the CEL light comes on do you hear the fuel pump? Plenty of fuel in the tank?

 

not neccessarily ruled out the ecm. would it start and run at all if it was the ecm?

 

When the thieves stole the computer, did they siphon your gasoline too or cause other mischief that you haven't discovered yet? Perhaps they also stole your fuel pump relay. At least take a casual look under the dash and under the hood.
If they were aware enough and needy enough to steal a YJ computer, (not all that easy to do) they might have stolen something else they thought they could use or sell. Have you looked at your exhaust system?

Good Luck, L.M.

 

If it's running when you dump fuel in the throttle body but dies when that fuel runs out, then it sounds like a fuel delivery issue of some sort. Fuel filter maybe clogged? Check fuel rail pressure with a tester. Anybody else have some ideas to throw at this?

 

I agree with dante2, I think the next thing to check is the fuel rail pressure. You may be able to rent or borrow a tester at a local auto parts store.
Let us know if what the pressure is. The link in post #5 will lead you to the published spec.

Good Luck, L.M.
