These are the codes that my car is throwing.

P0600 Serial Communication Link
P1000 OBD System Readines Test Complete
P2105 Throttle Actuator Control System (shutting engine down)
U0300 Unknown


I swapped my throttle bodys today with another stock one so I am not sure what the throttle actuator control system error is. My TB also worked fine on the other car.

Took the tune back to stock as well.

Cleared the codes and disconnected the battery for an hour.

Checked all of the fuses

Spark plugs are less then two months old and my injectors were just recently tested two months ago as well.

I have 37-38 on my fuel pressure and it jumps up when I go to start the car.

On my ignition it says my cops I believe it was refearing to is 12.5v (diablo tuner) I would go get the exact info what it was but my cars at the paint shop.

My my car was running perfect the best its ever ran. I caught my exhaust on on rail road track and it bend my exhaust. After the X pipe. I had an exhaust shop fix that. The pipe were just bent no major damage. The car ran fine from that shop to the other.

The car then sat for one day and the next day would not even start.

I tried starting the car with WOT and no go. When you turn the key it just keeps trying to turn over. It just keeps making that same sound that your car makes when your first turn your key.

Any wires ripped off when the exhaust was damaged? Anything to the O2s? If the car is turning over but not starting it sounds electrical. Maybe one of the grounds was damaged / came loose?

Thats what we are kind of thinking but I am pretty new when it comes to turning wrenches and I have done my best to chase cables and check the grounds. Any idea where some of the important grounds could be?

For the P1000, check to see if the MAF sensor is plug correctly. When I installed my JLT intake and updated tune for it I got the same code and it turned out to be that that sensor wasn't plugged in all the way.
