Default Need Help ASAP.

I finally installed my heads and cam. So today I took it to the dealership to have the cam signal crank signal reset. Well the guy puts the car back to stock along with the new updates to the pcm. I drive it home to put my edit program back in to it. Now the car will ideal for 20 seconds then shut off.

Here's the code that it shows.

P 1635 5 volt refernce 1 circuit.
p 1639 5 volt reference 2 circuit
p 1626 Theft deterent Fuel Signal not recieved
p 0453 Evap fuel tank pressure sensor circuit high volt

Has anyone had this happen to them. The car fine with the edit file in the car before the cam signal reset.

Thanks for the help.

I would guess that your problem is the third code...for some reason the flash screwed up your Theft Deterent System and the car thinks that it is being stolen.

You said put my "edit program back into it". did you save the file/pcm programing from the last time it was at the dealer? Reinstall it and modify.

Here's the deal. If you have a edit file that was created before you had the car reflashed to stock with the new updates. The Edit file will nolonger work. I had to down load the new pcm file and start over.

The dealership was clueless. The tech did like the edit program.

Thanks for the help.
