Never knew fuel pumps and injectors and coils were included in the preventative maintenance schedule. I got some work to do!

You could get that 4 banger ironed out. Pull it and sell it, there is your I6 cash.

They aren't but considering all the issues I was having at that I said to heck with it. I needed the new fuel pump it was bad. Only reason I replaced the injector was it was rusted were the connectors plug on to it. Coil wise same thing it looked beat half to death and the outer case was cracked. It may seem like craziness or just throwing parts at it but in reality it was trying to make sure the thing was going to be dependable.

So the fuel pump quit working and now the new one doesn't work? Strange.

Anyway... I thought my 89 was carbureted when I bought it. It is actually ECM controlled carbureted. The PO just unhooked all the sensors. So it has an ECM...

So maybe good idea to brief up on the engine stamping codes so you know exactly what your getting when you get your I6. Mine is 909CL29. I think the "CL" signifies the computer controlled carb, but don't quote me on that.

THIS is the one. Motorcraft! I went to buy parts from a guy off craigslist and he had a really nice built CJ with one of these on it. Said he was rebuilding the weber/carter whatever it was every 6 mos. Said he was running this going on 2 years like a champ. Loved it. Here is the link. I was considering going this route, but like I said, decided on tbi.

You have a power issue. The ignition and battery feed at the ecu need to be checked. If you needed a manual pm me. The fact that you have no fuel or spark means the ecu is not initializing.

Yep - that is a very common swap for the carter. Although, I have heard of some folks having issues with them when they receive them.

Aw, too bad. I was going to offer it to him for free on the condition that he first diagnose and confirm that it is in fact the ecu at fault.

It's out of the '95 (I believe) replacement tub that I picked up. Got most of the under dash harness too I believe. What's it worth? Prices are all over the place on ebay.

Ecu is at fault pulled dash after work tonight and pulled the ecu out opened it up and it had what I called a burnt spot on the board inside. I had my buddy test it for me. He is a certified jeep mechanic He said it is dead. On a good note though he has a 4.0 out of a Cherokee along with a ax15 that he is gonna let me have for little or nothing I just have to help him pull the motor and trans. He's gonna let me use his shop since dad's 57 Chevy is being tore down in our garage right now. Thanks for the help guys maybe this 4.0 swap won't be to bad and I won't end up back in the Stone Age with a carb after all. Again thanks for the help.
