Ok, swap is done. Car will start, idles at 500 rpm for a few seconds and dies. if i flutter the gas i can build the revs to 2k thats about it. Fuel pressure is set at 38, but exhaust smells rich? tried to adjust the aiv with no change so i put it back where it was. I know i have seen where people have reversed the fuel lines and have had problems. I would feel like a complete jacka** if that were the case. My Sard regulator is at the front end of the fuel rail and the pump side is between #3 and 4. Right? right. Anybody out there make it to time attack in Nash. SWEET! NICO IN FORCE!

Possible....

-Boost Leak-Vacuum Leak-Bad MAF-Bad coils

Check those, I'm missing one other thing I think. But I forgot. Check those though for sure, I'm pretty sure its one of those.

Hey, thanks for the ideas guys. Been workin fourteen hour days, so i haven't been able to do much. I did get a chance to check the water temp sensor and for codes. no codes, but i did realize i am not getting any vac. Should have been one of the first things i looked for. DUH! Was trying not to be a complete eco terrorlst and kept the charcoal cannister and all the other emision stuff. guess its time to start plugging lines and see where im loosing it. Should have been easy to see since i have both a boost gauge and controller. Thanks again.

Hey, GO240. do you have a list of codes for the sr? would be great for the future.

if your fuel lines are switched it wont idle.

Codes are located all over the place on the forum. check the FAQ's and search area. I am having to play the vacuum game tomorrow as well. good luck
