I own a 2003 pontiac bonneville and the problem i m having is related to fuel pump that was replaced and car was fine up until one day i was driving and the suddenly jerked and quit after ward and would not start. Ok so now when i turn the key over but not to start i can hear the relays clicking off and on. Also there is no power going to fuel pump,but yet the pump works i checked that out myself. Could this be a bad ground and if so where is it located. Thanks in advance.
