Alright guys, got it running again yesterday. Ran good and ran until it got to operating temp. Then after putting the exhaust back on the car, it wouldn't run again. What is going on?! Only thing I did to it yesterday was put my old set of injectors back in it.

 

So it still has the old set of injectors in it? And the only change since it was running is putting the exhaust back on? What sort of exhaust do you have? Does it have a catalytic converter? Maybe it's plugged and causing excessive backpressure thus killing the engine? You might try dropping the Y pipe off again and see if it stays running, or maybe as a test before that, check to see how much exhaust you can feel coming out of the tailpipe.

 

The exhaust is all brand new and it's one piece from the headers back to the bumper.

 

Car is at the dealership now, got it to run again but now it keeps shutting off for some reason, and I'm done messing with it.

 

Missed your text over the weekend. Hope the dealer can figure something out and get it back to you, looks like it will be a sweet ride when it's up and running.
