1999 Chevy Tahoe V8 Four Wheel Drive Automatic 129000 miles
I have a 1999 tahoe ls and have recently had very intermittant fuel pump failure. I replaced the pump when it went out almost a year ago to the day. After about 12 hrs or so it will turn on and work fine. I remember the squealing noise before it went out last year, and it isnt doing that at all. I replaced the oil pressure switch last week and it worked for a few hours, then tried it again and the fuel pump once again didnt turn on. I have checked the relay which clicks with the ignition and even wired up another relay and still nothing. Have a good ground and a 5 volt wire in the 3wire plug at the pump. Couldnt read anything off of the 3rd wire which I believe was a white wire. Any suggestions?
have the same problem?
