i just finished putting a new/rebuilt 4.0 in my 88 jeep cherokee and it
will not start! its getting gas and spark and all the plug-ins are plugged up. has anybody ever done a motor swap and know what i could check? the wiring on the jeep is kinda booty fabbed cause the guy i got it from wasnt a mechanic of any type!!! i have changed the wiring harness and the computer from another jeep to try to do away with the mess he had! the thing has a button you have to push to start it, why i dont know! im going to look into that tommrow and maybe change things from one jeep to another to get his crap fixed. so i need all the info yall got!

fuel/spark/compression
You have them all, but do you have spark at the right time?

I've had 2 motors, and I've already checked it out. It needs to be put all together and everything pluged in before you can trouble shoot it.
Or......
you can buy another junker that runs and sell that pretty new motor to me

fuel (gas and air mixture), ignition source (spark), and compression (compression)
you need these three things to run a motor ... you are lacking one of them.
or you fawked up the wiring and the ecu wont let it start for one reason or another ...
check fuel pressure, timing, compression numbers ... check it all.
dotn care if you have already done it ... check it again man ... soemthing is missing.
