Default starts, but wont stay running.

Hey, im new to this forum, although i have been on the site before searching for answers to my questions. now I am a member and Im having a hard time with my 93 cherokee. It starts and runs for about 1-2 seconds and shuts right off. recently ive put a 2001 motor in it and it was fine and running great for about 4 weeks and now this. Ive tried a new IAC valve, TPS and a CPS, none of them solve the problem. Any help would be great!

Did you take the computer out of the 01 and to swap into the 93. I could be wrong(never done a motor swap) but an 01 engine will not run if you have a 93 computer and electricals hooked up. Could be a silly question but you didn't give many details about the swap.
