2010 Camaro 2SS L99 72K miles. She was in storage w/ a dead battery but recently resurrected. New battery, new OEM ACDelco fuel pump & fluids. She cranks 1st time every time, idles smooth, great throttle response, and fast. However, CEL error w/ U0109 "Lost communication with Fuel Pump Control Module A" according to my budget blue driver OBD reader. I've reset the connection to the FPCM but error persists. That's the only code it throws - no P codes.
Any suggestions as to where to look next or do I need to get an expert involved with the high end diagnostics scanner? If so - any shops that I could trust her to in the north Atlanta / Alpharetta Georgia area? Thanks in advance - Tim
