3.4 Efi Swap

[Zeke&Me]

Hello Everyone! So I am the newest member to the forum. Picked up my first Comanche the other day. Its a 1986 2.8 4x4. I only had to trade 350 bucks for it. 8)

 

It had not run for 3 years. No keys and no title. (I checked the vin, not stolen... Have to get a new title). We were actually able to break the lock tumbler and it turned over first try with a jump. Not only that but we drove it home... about 3 miles. Suprised it didn't give us any trouble. Actually ran really well for garabage oil, dirty carb and old fluids.

 

Excited to get this thing on the road again. I have never owned a jeep... Just a bunch of pontiac fieros. I want to get rid of the carb and put a straight six in it. Any starting information you guys can offer is great. I am starting to poke around the forum. Ill keep you guys update. Pictures soon.

Welcome,Looks like you got a great deal on that truck .looking forward to the pics,and the build. I think it's cool that thing would even run at all after three years, must have been in ok shape when it was put up! It reminds me of mine, it was in a barn for two years but had  been put up with a few problems. Like a bad fuel pump, no working key cylinder and so on. The tank was full of fuel to the top I was thinking it was empty, man was I wrong, fuel had gone bad, the sending unit wasn't working so it sounded all the same to me when I was taping on it.Two fuel pumps later and a good tank washing, first one was bad out of the box, I got it to run . Sounded really bad but after 5 mins or so, it smoothed on out , now it runs good. Hope you have a great time with yours!

So, Finally got some pictures uploaded. Here is what we are starting with:

1986 2.8

5 speed

202,000 miles

Looks pretty stock. There is a decent stereo head unit in the car. :thumbsup:

 

So, I broke the carb's throttle arm while trying to clean it. :dunno: . I put a replacement in I got from a local shop called FN jeep. (this place is awesome!) It runs but it feels weak. I wanted to put a straight six in but I get mixed reviews on how easy/difficult the swap is. Some say it won't fit in the 1986 models so I decided i am going to start the 3.4 swap instead. I am also going to switch it to fuel injection because gas is expensive. So I went down to the junk yard and started digging. The first one I found was in a 95 camaro, but it had fire damage.....sooo much damage I couldn't tell where it started from. So I left. I went to the next yard which proceeded to send me to another yard down the road. They just so happened to have a 94 firebird with one in it. So i walked down with my tools prepared to take it out. I get to the car position and there was one already pulled on the floor next to it. :banana: :banana: :banana:  Yay! No sun labor today

 

Payed about 270 for the complete. Went straight to my machinist and dropped it for a full rebuild.

 

 

They are gonna clean it up and tell me what they can do. Might get some head work done if the price is right. I will keep you guys update as I go. \

 

So far we got a new battery and a new ignition tumbler in. It feels nice to have keys for it. :) Getting excited.

Sweet!  Great job getting the used motor to a machine shop before installing it and hoping it will run.  There aren't many people who go through that step first!!
