No i sure havent. Lets start here when the car was running it ran great until you rolled the windows down then the car would lose rpms and die, but start up instantly after a week of this it started taking longer and longer to start. Now wont start at all and no power to fuel pump but I get power to the gas gauge.

Either you have a short or a bad PCM or BCM

I believe that the BCM is body control module but what is the PCM

something is screwing with the signals.. I don't think that the BCM controls the power to the fuel pump, But I could be wrong.


Did the car recently get really wet ??

Try checking the plugs on the BCM and PCM to check for corrosion

My guess is you have a problem there. Or your Bus Line in the dash is shorting out
