Ok everyone. All the people and shops I have had try and figure it out. McKinney Motorsports got it.

These guys are super cool and no what they are talking about. I don't usually have issues with cars I can't figure out but if I do again I will go to them hands down. Didn't even take the car off the trailer. ECU was going crazy because some how it was getting 2 signals for fuel. And some how the motor was running on fumes with pump off. Also the signal wire (orange) ignition wire on my wiring specialties harness wasn't sending a correct signal some how. We required that and got it to work.

McKinney Motorsport. In SoCal all day.

They know their shit, they've been doing this for a long time. Glad you got it figured out.
