My car just quit running on me in traffic as I was driving along it quit no warning no check engine light. I could not get it started right away finally it did but I had to give it gas. I got home put my obd2 reader on it anyway it brought up the P0001 code. So I put a fuel pressure regulator on it and coils and module and air filter. When I start it after it warms up it shuts off, I start it back up it runs a few minutes and sounds okay when it is running. I cannot figure it out.

Hello,

That code is a communication error that usually means the computer has gone bad and needs replacement. If you get a new one it will need to be programmed but a used one should plug and play.

Here is the location of the PCM (below).

Please let us know what happens.

Cheers, Ken

A shop or the dealer must do it. Unless you have a scanner that can reprogram.
