ECU - Manual vs. Auto

[LoTGoD]

Nothing accomplished again tonight. Feels like an endless spiral right now. Hopefully Wildman will make it over here and make all the pain go away!!!

It lives! :cheers:

 

Always remember to put in the correct flywheel when installing a HO trans in to a Renix Jeep...

 

My apologies to Hornbrod for not reading his description of the Renix flywheel correctly.

 

Many thanks to Wildman, Hornbrod, Pat, Jeff, and anyone else that I might have missed in there...you guys rock!

 

Need to button everything back up, and possibly drive it around the block tomorrow.

So it boiled down to the wrong flywheel?

 

Sounds like something I might've done.. :yes:

Amen brother! I will have you know that I un-bolted, and then re-used, the 2 star head bolts on the top of the tranny !:brows:

 

Used a 10mm socket to get them off :clapping:

I'm calling the nice young men in their clean white coats to come and take you away, cause you're....

 

APE S#!^ INSANE :nuts: :nuts: :nuts:

I'm glad you got this figured out,

 

sorry I tapered off after trying to help,

I've been scratching my head here trying to troubleshoot some other stuff myself

(the 'sidejob I mentioned involved $30k worth of pizza ovens that wouldn't start).

 

 

 

It's easy for me to say now,

but the wrong flywheel was my very first thought,

(easy mistake to make and it won't run with the wrong one)

 

I even bolded it for emphasis in the original post :smart: :

 

I'll try to pull out the 4.0L (Renix) FI manual later tonight (have to go out to do a side job right now :ack: ),

I'll also try to read some of your other threads, and see what else I missed.

 

So you have:

a Renix 4.0L engine, with a Renix flywheel, Renix distributor (that has not been pulled out), all renix sensors (some replaced/tested/etc), a replacement renix harness, and a tested working Renix ECU.

 

Renix 4.0 - Yes

Renix flywheel - yes (looked at the HO flywheel and determined it was an HO flywheel from Eagle's description)

Renix Distributor - Yes, never changed by me

Renix Sensors - yes, no swaps to anything newer; tested and tested again

Replacement Harness from an 89 MJ

ECU - Tested in friends 87 and it fired his up

 

 

I'm glad it's running,

hopefully the hard part is over now :thumbsup:

I hope the hard part is over as well. Need to reinstall the rear drive shaft, dash, and all the other little stuff.

 

The confusion on the flywheel was Hornbrod's description that I failed to read properly. Once I went a re-checked the flywheel that was sitting in the corner, talked to Wildman on the phone, and looked at the pics of the Renix vs. the HO flywheel online, I knew I screwed up.

I posted a pic of the two side by side a few years ago on JU,

not much help now :smart: , but here it is :D :

If it helps, I *almost* made the same mistake when I put the engine in my MJ. :doh:

:doh:

 

I was freaking out thinking somehow wiring harnesses could have gotten mixed up or screwed you up or something on my end.

 

 

...karma lol. I'm glad that you have it running, and not so glad that it took so long.

So that phone call I got late yesterday morning, on my way back made my trip even better.........Hearing that you were up and running

 

:banana: :banana: :banana:

 

Like I said the other night.........just maybe a good phone conversation over what the problem might be, is better than all this typing :headpop:

 

:teehee:

 

 

I was really super glad to hear that it fired right up :D

 

I was planning on stopping on the way back, so I ended up missing that steak dinner :(

 

But, you said it best, now you know, and had a Great learning experience over this :thumbsup:

 

Button it up, and get it on the road

 

Who knows...........I just might be in your neighbor hood some time passing thru ;)
