Okay back at the shop today messing with this. I thought I was getting somewhere till I wasnt...
Seems to be a short or something? I dont know if I read it here or where but someone said they had to slightly pull on the OBDII to get it to read. It worked. I had tried to clear the codes thinking if it would work, great before I could read them. When I FINALLY was able to read them, I got a U0073: Control Module Communication Bus "A" Off. I thought this might be related to the short on the OBDII. I cleared it again. I started it and it was perfect! LOL well... for the most part. I could watch the live data through the OBDII. Idle was mid to upper 600's. No codes no nothing. The ONLY thing, (and I was sitting still so dont know if that is the reason), I could not rev it past 3500/3600 range. BUT, when I would rev and let off, it would come back to 600ish and idle out. I could not get it to die!
Then I got to thinking... I could not hear my fans for the radiator. As mentioned, I have the black box thingy that everyone suggested. I did buy it used so not sure if that is the issue. I talked to the guy that makes them when I installed it and sent him pictures but he seems to think everything was fine. There has always been a question on what does what. His pictures and documentation seems to differ what I have. I put the fans on my second switch when I installed it. Switch 1 is traction control. It turns the light no the dash on and off. Prior, the fans were running all the time so I thought maybe they were wired or set to "always on". Well, after resetting the CEL, the fans were off but it ran fine. I could cut the fans on and the would come on but this is the odd part, the live data on the scanner, would freeze? I turn it off, and it would pick up where it was at? Okay... well I dont need live data all the time but the engine seems fine now...
Unplug the scanner. Start the car and right back to the same thing! Rough idle and fans on even though the switch is off. Plug up the scanner and look at the live data. It is low. I turn the car off, check the codes (same) and do another reset. I start the car, it fires up an dies. Okay, I do it again, same. I check the codes again and now I have a P1604 which is a Stat Ability Malfunction. I check the "Code History", and I new see a P0172 System Too Rich Bank 1 code that is stored but not present.
Now the car wont start. Cranks and dies. Nothing more. Think it could be an issue with that black box? Someone asked above what all was done to the car when it was apart. Once again... nothing engine wise. Electrical, we did the black box, a radio, wired a standalone switch system (which the black box is controlled from and interior lights), and put in a new battery. That is it. Nothing with the motor, trans, exhaust, fuel, nothing. Nothing else was touched while the car was down and it ran fine prior.
