Alright, heres what I did. In my 1988 jeep cherokee I swapped the Renix engine for the HO, I swapped over all of the Renix sensors and equipment, and adapted the tps. So basically I did a HO head swap on a Renix block. I also swapped over the distributor. Here's my problem, I set the engine to tdc cylinder one and the distributer at 5 o'clock, start the jeep it idles like crap and will not rev up, I therefore retard the timing, I can get the timing so that the engine will idle but I cannot for the life of me get the jeep to anything but idle, meaning it wont rev up. If I do press the throttle it chokes and backfires and will not rev above 1000 rpm. If anyone has an idea that would be great. BTW I have searched for possible answers one being that the timing chain being off, but I would much rather see if there is another answer first before I dive into that.
Thank you,
Kevin

Yea, that can be tricky, I just replaced the Distributor in my '89 Renix and (like an idiot) I didn't mark where everything was so I had to do the whole TDC and get the rotor to point the right way, took a while but got it eventually. Good Luck.

^^yes which would be at 5'oclock, I've reset it there many times but with no luck.
And thanks I'm getting the feeling that I will need a lot of luck to get this thing running.

I see now but wouldn't that still put the distributer facing towards the no 1 cylinder on the distributer cap? if oriented like the picture, cylinder 1 is at 5 o'clock if oriented from front of the jeep no1 is at 9 leaving the distributer faced the same direction.

the metal piece on rotor has to p[oint to number one in the circle when motor is at top dead center on compression stroke then run spark plug wires around the cap matching the number 1 to 1 2 to 2 and so forth
