Ok, i'm having a major problem. I just got done installing a corsa axl back exhaust on my 2007 GT, and now she won't start. This afternoon i received my SCT xcalibrator from brenspeed. I programmed the car to 93 octane. After that was complete i started her up just fine. Didn't take her for a spin because I had the kids here with me. That was around 430. We started working on the exhaust around 930, and just finished up. I tried to start her, (remote start) and no go. It seems like she wants to turn over, she starts too, then she dies. I tried to start manually, and no joy. I gave up, and am now feeling a bit queezy. Does anyone have any suggestions?

 

You have a lot going on here....

1 - I really doubt an axle-back exhaust could cause a car to not start. This is an '05+ car, right? Doing this exhaust does not involve the O2 sensors in anyway, so I have a hard time thinking that is what caused your issue. Even an exhaust leak would not be much of a problem because it is after the sensors. This a no brainer swap.

2 - The tuner could certainly be the problem. The computers on the newer cars are very touchy. I would return the program to stock tune and try to re-start.

3 - Remote starters? I hate 'em. They are worthless if you ask me. They cause nothing but grief and problems. Anytime you mess with the ignition on a car and internal security features, you are asking for trouble. I know some here will not agree with me, but you won't find me putting one of these on any of my cars. This could also be your problem and how it interfaces with the new tune.

Hope this helps and good luck.

 

Well, a little progress. Flashed it back to stock. At the end of that it said check the fuel cap. Looked at it, it's on, thought maybe i didn't put it on all the way when i got gas. Started her up just fine...well maybe not just fine, but started none the less. So I tried to reprogram with the 93 tune. During that process the info on the odomotor said "FUEL LEVEL LOW DTE ODO DATA ERR"....after the program was complete it said to check the fuel cap. Tried remote start, and that cycles through 3 times if there is failure. First and second time no go. On the third time she started and idled, but sounded weak. It is 12am, so didn't want to **** off the neighbors anymore than I already have. At least she started.
