08 Vortec Max CNG
I have a 2008 Vortec Max with a 6.0L that has been convertered to run off
of Compressed Natural Gas as well as gasoline. It is driver controlable to pick
what fuel to run off of. When running on CNG it is setting P069E in the Ecm and P2635 in the Fuel pump control module. I took care of the P069E in the Ecm with Efi, but the P2635 is still commanding the MIL through the FPCM.
Any ideas?
Thanks

The fix is done. It is a sub processor for the Fuel System Controller ( unit usually located above the spare tire). The install is a 6 wire hookup to the stock controller wiring harness, and one additional wire to your lockoff solenoid to detect LPG/CNG operation. The unit is fully weather tight and mounts by the stock Fuel System Controller module. Contact Technocarb Equipment for one, ask for Brad 604-854-6264 and he can set you up.
