  1. having trouble. anyone ever get a bad oil pump? i have a 1992 4.0, " rebuilt" the block new bearings new rings, new gaskets, honed cylinders full valve recut and head job, compression varies 135 to 145. figured while I'm in there new oil pump, but.... ever since first fire up oil pressure is up there. i started with a mecheanical gauge. it read 85 pluss psi.but engine ran perfectly. no ticks no weird noises nothing, if wasnt for the guauge you wouldnt know different. figured its fine. fast forward 7000km. swapped out to oem guages. oil pressure still reads high, maxes out the gauge when running above 1500rpm. loads of oil in the top end. when you shut if off you can hear it pouring down. so not plugged filter. lots of power. engine seems to be happily broken in. decent fuel mileage 400km to a tank 6.5 inch lift with 31s, however I'm concerened the high pressure is going to cause issues. i can hear a mild tick now when its running. I'm thinking lifters? maybe the pressure is too high? I'm not sure. could be exhaust leak too. its tough to narrow down. i have never seen a pump push that much oil before. it was a stock spec replacement. but its an engine tech brand. thinking chinesium? either way i don't think the pressure relief in the pump is working proper. thoughts? spec in my haynes book is 12 psi hot idle. 45 psi above 1500 rpm.
  2. well having done a 4wd conversion. its pretty straight forward. everything just swaps over. the only issue you will have mechanically is the rear driveshaft. the 2wd and 4x4 shafts are different length. shifter spot in the floor is just a cover plate. so you can just put in the shifter from the xj. i loved when i did mine. i thought it was goining to be this huge pain. but it turns out jeep just had one body for both 2wd and 4wd. all the bolt hols were there and threaded for the skid plates too. by far one of the easiest swaps i have ever done.
  3. how hot is the engine? ive had 92s do that when they over heat. with idiot lights i guess its hard to tell. maybe pop hood and let cool down?
  4. i guess maybe i wasnt specific.. sorry. i have a running and driving 90 that has an ho motor in it with a renix ecu. hard starting tho. trying to figure out why but not solving it. i have a 92 comanche i have been slowly pulling parts from. it still has the complete wiring harness ecu dash everything. i plan to pull dashes from both jeeps and swap interiors. ( 1 is grey one is red. i like the grey more) at the same time i am putting in ac. now being that everything will be apart thats the time to swap ecus and wireing if.... its worth it. otherwise i won't bother. otherwise ill just leave the renix alone. but i would like better starting and a cleaner wiring system..
  5. so ive looked and looked and i haven"t found much info. so i finally did my ho swap... but its in a 1990 renix. now I'm sure many of you know renix wiring leaves alot to be desired.... now i have a 1992 comanche complete... minus alot of stuff... but the full wiring is there. is it worth swaping harneses over from the renix to the 92? yes i know its alot. I'm also planning on installign ac that will be coming out of the 92.. so dash and everything will be apart so thats the time to do it. i have everything i need. but is it worth it? i have a starting issue i can't seem to nail down either... thoughts?
  6. Ok so uptdate i pulled the ho out and slaped in another renix 4.0 i have runs perfact. So whatever the problem is or was is in the engine itself not the wiring.
  7. On ecu plug 15 pin connector, number 3 on left row is ground, pin 7 on right row is tps input, pin 15 on right row is tps 5 volt supply. Testing pin 3 to 7 shows 2mohm resistance. Testing pin 3 to pin 15 shows no connection, infinite resistance indicating no connection. 0 continuity. That's best I can describe it. I'm not sure how to upload pics. But I found the fuel injection manual for jeep renix engines. So I have been going through it to get a better understanding of what everything does. And how the sensors react to help the ecu.
  8. Lol sorry when i first set the tps i had proper voltages. And readings. Then i had to pull the intake off and replace the intake gasket with the proper one. Had to change the intake out for a different one because the old one was cracked. After putting the new intake on. I reset the tps. But the refference voltage was 4.82 instead of 5. Test ran any way. It sounded like the ecu wasnt getting proper readings from the temp sensors. So i pulled the plug from the ecu. And was checking the readings from sensors. I then checked resistance and continuity from the tps. At the ecu plug i had a high resistence from the ground to input signal. Wich makes sense given throttle was closed i then checked ground to refference line i had an infinate reading. Meaning no connection. I then check continuity on those same line. I have no connection. From the ecu plug to the tps on the reference line out. If that makes sense. I'm figuring moving wires around might have broken one or more.
  9. 3 flat from tps. Then i was checking at ecu plug
  10. Checked and replaced. Altho when i was setting the tps. It had 4.82v coming from ecu. I was checking comtonuity and resistance readings from temp sensors at ecu plug decided for giggles check out reading from tps. I have return reading to ground but no supply from ecu going to tps. I'm wondering now if there is broken wires in the harness
  11. I think I'm going to cry. I pulled the intake off. Put in the proper gasket. Put it all back together. Now its flooding bad. Checked wires sensors. Everything is good. I did find a crack in the intake so had to replace it. I don't know what to check. And i don't want to take it to a local dealer. Because frankly i don't think they have a clue about these trucks anymore.
  12. Ya i pulled the intake off last night. Way different. I'm not sure how i missed it. Going to get a new renix gasket sent over today
  13. Orange and black wire is dash lights. But feed from running lights. Mine has a relay under the driverside dash that kicks on exterior running lights. If you pulled the dash out there could be a pinched wire somewhere.
  14. Ok so the only thing i did wrong was the intake gasket i used the one for the ho not the renix. Mmm. Also worth noting i have to ho exaust system on it. But intake has been gorund in the correct plases already. I know its not the problem it was on the old renix for six months prior and never had an issue. I'm going to pull the intake off and double check the gaskets . I set the time exactly how they say. Not exactly my first time working with engines. Lol ill see how it goes
