Default Starting problem after DPFI to MPFI swap

So I swapped over my wiring harness like the diagram says but now the car starts up and instantly shuts off. I replaced the IACV, and tested the distributor, changed some wires around and still nothing. Every once in a while it starts for about 3 seconds, revs to about 3,000 and then kills itself. All the nuts are tightened down on the throttle body, manifold, etc. If anyone knows whats up with this problem let me know, I would really appreciate it.
