  1. 90 xj. So i need a 4.0 automatic ECU? Cole
  2. Is there a difference between the Auto or manual ECU for the 4.0??? I need to know cause the ECU i found is a Manual. Thanks Cole
  3. I will try that the ECU borrowing fell thru he had to go out of town this weekend. I may have found one for a good price so i might buy it and see if it works. Man this thing has made me nuts trying to get it going. I am gonna sell it now because i am running out of time to work on it but i want to get it running so it would be worth more. Cole
  4. I have pressure and floe just no power to the injector. I will look at that relay as well. Cole
  5. runs on starter fluid like a champ i have done a thorough sweep and narrowed it to the injectors hot side. Has ground on the plugs for the injectors but no power. ooked up a spare injector that had the end removed so you can see it fire and nothing this same tested had worked during the timing problem. Like i said its a all of the sudden thing. I had the timing wrong but had fuel i then fixed the timing and tried to crank without any luck. Was thinking TPS because it controls the injectors pulse rate but it goes into the ECU to do so. Maybe i can borrow a ECU from a buddy and try that?? Any other ideas. Thanks guys. Cole
  6. Swap all renix sensors and distributor over and use the renix computer. Modify the TPS to work on the newer TB or use the renix intake and TB(suggest boring it out) and it will work. SEARCH for 40ho with renix computer and there is a thread by me asking abotu it and I'm doing it right now. Cole
  7. I have been working on a XJ and now the injectors don't seem to get power. I am not sure what controls the injector firing but it must be broke. I need to get this thing running so i can sell it cause i don't have time to deal with it nowthat i am leaving early. Thanks for the help and suggestions. oh its a 4.0 auto. Cole
  8. Fishin pole one works great Get the top half of a light action rod and it then bend it in half so that it will pull string longer like this video. Cole

    Cut the light buckets out and mold them into the front of your MJ so you can run round headlights. I want to do that on my Xj if i can find the headlight buckets for it. Look at Detours offroad at there black XJ they did it but didnt have much info on it. Cole
  10. Oh and between us all we should make a DIY thread using the easiest built and then each of us with variations of that one chime in with what we did to get it to work. I think staying all renix fuel system is the easiest sounding with my cluster being a harder version. OH and BIGMASS did you not use the knock sensor. I left mine off and then hooked it up but didnt put it in the block just to eliminate it as a problem. I think my TPS is my problem though i got it backwards maybe. Cole
  11. Relay i would say as well. If you wheel it i would switch it so you can turn it on all the time when on the trail. Cole
  12. for those that have cpmpleted this what injectors renix or HO. And if you use renix fuel pump will it run the HO injectors? i got mine 2 crank but it doesnt idle well and it will not rev up. it seems to be lean. i am running HO injectors with the renix fuel pump. i am ready to rip it apart AND START OVER. EDIT cause I'm alittle to caught up in this to realize i had mess the TPS up and it was reading back wards as in 4.87 at idle and .08 at WOT sooo that may be my issue not the fuel pump but just for information which injectors are you guys running??? Cole
  13. The motor came to life today but I am having some fuel trouble. I don't think I'm getting the pressure i need but i am going to do some buttoning up tomorrow and maybe do the rear lift or at least prep for lift. Hopefully after 2 days of troubleshooting i will have some luck tomorrow. I also changed my first CPS and it was alot easier then i have read. Ill try to get some pics up tomorrow night. Cole
  14. i have one on my new xj. it has the bubble and it shows temp and such. If the bubble is keyless can you get remotes for it? I thought the bubble was for the temp? Cole
  15. I believe 1/2" of play total both directions in the longest open span is a good way to check. Thats what i follow most of the time so i hope its close to being right. One of those old timer things i picked up when i started working on vehicles. Cole
