2012 Camaro LT V6 No voltage at fuel pump supply wire on FPCM.
This is my first time ever using a fourm so if i have things in wrong place please sombody help me. LOL ! Thanks! I am working on a 2012 camaro LT V6. I have a code Po62F Internal Control Module EEPROM ERROR & U0109 Lost Comunication with fuel pump control module 'A'. Checked all fuses and connections,Cleaned FPCM connection and checked for water damage none found.Did not take module apart and look inside.Tested out of range/no signal tests.,Got Ingnition volts 12.25 ,Battery Volts 12.06 & Have 5V Ref of 4.94 Volts.Then did DC test and have no volts when KOEO But fuel pump comes on for 1 to 5 seconds, but no voltage change.DC test is checking gray wire coming FPCM to fuel pump.Cleared all codes only the U0109 will return after two or three key cycles everytime.Im not sure if the volts come from ECM or FPCM ? Any help would be much appreciated. Thanks!
