I am not gettnig a code 12 now. Does that mean that the ECM is bad? Or could it mean something else?

This damn fuel injection is driving me nuts.

 

Also will the 730 ECM give code 12 with the memcal removed?

 

No memcal, no codes.

 

interesting. So I must have a problem with my memcal then. Would that let the car run for like half a second then shut off? even if I give it gas I can't keep it running. it will fire a bit then shut down. Hope fully redoing the memcal will fix this.

 

Sounds like VATS is messing with you. Did you turn it off in the prom?

 

Yeah I did. I will recheck it though. My programmer has been acting strange.

 

Sound like you may be going into limp home mode,
w/all your mods the limp home chip will not run the car.
Try a reburn or a diff. prom and check your contacts maybe.
