05 gtp swap into 03 mc ss start and stall

[GTPSHAWTY]

Just finished the swap....2005 gtp entire front end swap in 03 mc ss .. Problem us it starts and last for about 4 seconds and die... If I plug maf up it dies in one second...... Another thing it revs up to 3k when it does crank..... I have good fuel pressure good spark new iac new map... all vac hoses are new and hooked up fpr is not wet around nipple....

Check the transmission harness. It may be unplugged in one of a few areas. Or you have a vacuum leak.

all are hooked up and in good standing

Hope your using the GTP PCM not the monte carlo one

Edit even that would not work because the pcm is going to need to match the vin. cant just plug a pcm in from a different car and it will run.

i got the pcm out the monte tuned with gtp file written in it..
