1999 GMC Sierra PU...Fuel Pump Question? Low fuel pressure...Replace...or Do Nothing



I took my truck into a local garage…

the tech…said he checked the fuel

pressure…and it was low…He recommends that I replace the fuel pump? Truck runs fine…but sometimes

now…when truck warm…takes a little longer to start??? What should I do?


For now, turn the key to “ON” and wait 5 seconds before turning to “START.” Eventually you will need a new fuel pump. I recommend scheduling the pump replacement at YOUR convenience rather than waiting for it to die and leave you stranded somewhere on a cold, snowy night.


What was the original reason for visiting the mechanic? Were you having problems with the fuel system? What made them check the fuel pressure in the first place?


Replace the fuel filter first, regardless of how old it is.
