Thanks for ALL your help Dave & everyone else!
I successfully swapped the engine, it cranks BUT no start!
Fuel pump IS NOT engaging!
I have changed out the CPS with the one from motor I installed on the swap; no change... engine cranks BUT no start! Also removed the SKIM from steering column and switched out the PCM (from a '99 Cherokee without SKIM setup) and at first the Key Void light on dash went out BUT now suddenly reappeared! What is causing fuel pump to not engage and without knowing my "key code"; How can I get jeep to recognize the original Damn key; the one that goes w the vehicle! It forgot key code but now how do I get it to recognize it! And how can I get fuel pump to engage?
HELP

Finally fixed pcm issue
Ok Everyone who posted and helped me with my engine swap issues...I have finally gotten My Jeep back on the road.
After months of headaches and trying just about Anything, I had to take the jeep to the dealership; and for the"small fee" of $395 I got a new key w the chip in it and my PCM to communicate w engine... However that still did not fix jeep; the problem was with the ASD relay from the PDC; A wire was broke and had to be replaced! The ASD (Automatic Shutdown) was not communicating w the PCM and after replacing wire THE JEEP RUNS BEAUTIFULLY! No more SKIM issue and/or PCM Issue. I no longer have the key void on dash and jeep runs perfectly! The ASD was not allowing the fuel pump or the coil rail to spark; thereby giving me months of Pain in the Asssets; However I have a new key and jeep is fixed!
THANK YOU TO EVERYONE WHO POSTED & HELPED ME ALONG THE WAY!
