Hello! My name is***** to JustAnswer.

Do you have a scan tool?

If you just want to get it started? Try disconnecting both battery cables and touching the cables together.

I found this. Do you have a sun roof has it been raining or ran through a car wash?

  • Some customers may comment on an intermittent malfunction indicator lamp (MIL) being Illuminated with a message or an indicator that displays Reduced Engine Power.
  • The technician may observe on a scan tool DTC P2138 – Accelerator Pedal Position (APP) Sensor 1-2 Correlation set as Current or in History.

Cause

This condition may be caused by water intrusion into the instrument panel (IP) to body harness connector, which carries the APP sensor signals to the ECM/PCM. This water intrusion results in a voltage difference between APP Sensor 1 and APP Sensor 2 that exceeds a predetermined value for more than a calibrated period of time, setting P2138.

Hello and welcome to JustAnswer!

There are many possible causes for a no start condition and it's going to require some electrical testing to determine what is going on. A scan tool will almost certainly be needed for an accurate diagnosis.

Have you checked fuses?

Does the fuel pump run when the key is turned on?
