My 99 Denali died on me so checked everything out and everything pointed to fuel pump being bad. Now put new pump in and relay but still pump doesn't run. Tried sending power through the fuel pump prime wire by the booster but nothing. Even jumper end the two leads for the relay, checked ground on frame. Now thinking its more of a wiring issue. We checked everything at the plug when testing old pump and everything seemed correct. It has the upgraded plug already as I put a pump in about 2yrs prior. We even sent power to the old pump with my power probe and jumpers for the others connections.
Has this ever happened to anybody else? Just looking for a couple more ideas to check when it gets light out again tomorrow. I love my Denali and can't stand seeing it broken down!! Any ideas or info? Thanks in advance!
