HELP! Check engine light flashing !!!
Looking for help, I just recently tuned my car. I installed long tubes, PP ported TB/IM, car ran great after the tune.
Pulled  hard no issues......Then 2 or 3 days later I was driving to work and noticed the check engine light was flashing rapidly.. Car still drove fine. I took it to the tuning shop they checked for misfires and found none. Did find a code p2635 I believe..? it was a fuel pump related code that was turned off from the factory... my tuner also checked another tuning software for forced induction vehicles and saw that my fuel pressure sensor was sensing low... Basically said he believes the fuel pump is going bad. Any way I can test this, the car runs fine? I noticed the check engine light stops flashing and STAYS on if I turn the wheel left while driving, when I turn the wheel right while driving the check engine light DISSAPEARS. HELP PLEASE |

First guess is that there is a wiring harness getting melted by the headers. Check on the drivers side near the steering knuckle. If it comes and goes when you turn that’s the first place I would look.

After looking for the above, I would also look to see how tight the wrap is on the harness going up the steering column.
I had issues with my right flasher coming on, even with stalk in neutral. I made the dealer appointment, but then noticed it was only with the wheel down, the tech said it was a tight harness and putting the wheel down stretched the wires and activated the lights. |

Agree to check wiring. Passenger side below the coolant reservoir is where most people have problems.
