Fuel Injection

[Old Dog]

I don't know anything about the smog police, but Howell claims their's is cal. legal.

I've had Howell injection for about 10 years now.Its not to bad but you have to know it.They originally put a Mopar on when it came out but it was a real pain to dial in.So we went with the Howell and they do have a Ca. Legal chip.It uses a late 80s GM P/U style 2 bbl Throttle Body and computer.You might have to keep your emissions stuff on for Ca. I just have the EGR valve left and canister.I ran a fake hose to them for passing in Arizona.Sure got rid of a lot of crap under the hood. Howell is pretty good to work with also.

I don't know if a 81 had a smog pump or not.I got questioned on mine but told them I had one without a pump which I did.Emissions people out here are low paid by the book if they read it IDIOTS.

After the prior discussions I decided to make the Mopar Fuel Injection swap, after all the biggest problem would be handled by getting the Carb off the Jeep. The day started off alright, I was able to locate a Wrecking Yard with a '94 Cherokee. The Fuel Injection and Exhaust look to be still complete and the Wiring with Computer intact. They said $300.00 for the complete list of parts which seems good for a Mopar Fuel Injection.
My next call was to the CA Smog Referee...our system is broken!!! I cannot make an appointment until the vehicle has been modified but I can only discuss this until that time, with nothing in writing to go by.
I will have to keep you posted, it may be easier to do a complete engine swap even though I would rather stay with the 4.2.

I just found this link about the Howell Kit, it is legal in California and here is the PDF from the data base;

don't worry cheap, its ok.
I think that I may have discovered the California Smog (Idiots) Police's Guidelines. i will most likely need to purchase an "accepted kit"

Please let us know how your injection system turns out, I have a ca. jeep also and not sure if I will be able to live with the YF. I will be using it at altitude often and doubt it gona run worth beans.

I have purchased the Fuel Injection, Exhaust, Ignition, ECM and Wiring Harness with all of the Sensors from a local Auto Wrecker. I still need the 4.0 Head but that will have to wait.
The California Smog Referee was extremely helpful, go figure! This really falls under the Engine Swap parameters so you need to get all of the Components and Sensors. I will removing the gear from a 1993 Cherokee.
By the way, I went up to my Cabin at 6300 feet and the CJ ran poorly, as expected! Thanks to the previous posts and links I am confident thats this conversion will turn out as expected.

you done good getting the 93. i think they stopped using that renix sourced junk in 90 or 91 now you just need to find a head from a 92 and up and you should be good to go. was the head off the 93 any good?

Grab an HO head, engine wiring harness, alternator and OBD I fuel injection system from a '91 to '94 Cherokee. You'll need a Hesco crank position sensor that reads off the crank pulley as well. There's a lot of information written about it on the CJOffroad forum. HESCO is also an excellent source.
