I have read many thread about the fuel pump but have not been able to solve my issue, so here it goes. CEL came on the lean mixture right and left codes were showing with engine rough idle below 1000rpm. changed fuel filter went to start engine, cranks but will not start. then checked relay and all were good, not sure if got the correct one, dealer said should be #395 in position #19 in fuse box, but in that position is #404 part number 4H0951253C. but this is the part number that the gave me. anyway, still does not start just cranks, so I then changed both pump because I had to open both sides anyway. after replaced tried to start, nothing. checked fuel pump, not turning on. no gas from fuel pump to engine. took line off, no fuel to engine. pumps are not turning on. so, pulled cable to reset computer, tried again will not start, pumps are still not turning on. checked engine for codes and it has P1937, generator not connected to B+. no clue what this means other than I have an open circuit somewhere. I am stumped and need help before I have it towed to some shop that will charge me $$$ and not get it running. any clues? I will try anything right now. BTW car has 103K miles and work fine until this. no symptoms, just started and then died!
