got car to run and idle.
forgot to swap polarity on CMP connector. was still wired Ls1 style. boom.

however it runs bad. cylinders 2,4,6,8 are hot, but 1,3,5,7 feel cold on the header tubes

dont think its firing on half the cylinders. barely idles at 560rpm(supposed to be around 800rpms) and couldnt get it over 1280rpms.

throwing a code P0200

bought motor fresh in feb 2011, ready to see if it is willing to live in this car. the 725hp dyno sheet keeps teasing me.

heres a video of it running

well thanks for all the input. just kidding, it was kind of a shot in the dark, but i figured it out. had a shorted wire for injector #3 which was making contact with 12v switched power to all bank 1 injectors. ended up running all new 12v switched power to each injector and new wires from pcm also. couldnt get at harness shorts, as they were behind the fast intake. no room. then ran a new switched power wire to coil connector. was a headache to figure out but it runs on 8 cylinders now and sounds alot better. thing is extremely loud. i have no exhaust. ha ha. here is a short clip. ill post a better one when i get everything buttoned up and heat shielded. 1year of wiring issues. i pretty much know how to build a harness from scratch now. wiring is an ugly learning process. im excited to see what this beast can unleash.

btw- no MAF and was messing with throttle tryig to get a steady idle. wasnt holding idle, but with a mm of throttle it would run smooth
