Just now noticed too that when I cut the key off. Some assessories stay on.. if I cut ign key off and go back to crank it. The lift pump doesn't do that loud lifting noise as if it never cut off. Cranks and starts fine though

Hi ,My name is***** will be glad to help. We can follow up as needed on here, Give me some time to review your information and post my responses. Im not an employee of the site but I help on here as time allows in between jobs. Response time will vary depending on my work load , etc. If all fuses/relays test good you can have a poor connection in the gauges and instrument cluster withing harness of a failed cluster if power and ground are present but the gauges do not respond.
