I think my fuel pump may be going out in my 1999 tahoe?

i was coming to a stop when my truck stalled like it ran out of gas. i tried to start it again but it kept turning nuthin. i did notice that sound that chevys make when the truck runs or when you turn the key was not there anymore. i also checked the relay and that is good. so im out of ideas. some ideas or solutions would be goodI think my fuel pump may be going out in my 1999 tahoe?
You need to do or have someone perform a fuel pressure test. There is a test valve on the feed line up by your fuel injector rail or throttle body, depending on what you have. If fuel pressure is good, approx 50 pounds of pressure, then check for ignition problems after that.I think my fuel pump may be going out in my 1999 tahoe?
You need to isolate fuel problems from ignition problems. Start by spraying some quick start in the intake. If its a fuel problem it will momentarily run on the Quick Start.



If it is a fuel problem it could also be the in line filter. Its a regular maintenance item to change.I think my fuel pump may be going out in my 1999 tahoe?
I agree with the first answer. If I learned anything this summer working in an Auto shop is that fuel pumps do go bad on Tahoe's and Yukon's so its a good possibility, pretty easy to change out.I think my fuel pump may be going out in my 1999 tahoe?
Change the fuel filter first! I have see this on allot of 1996 tahoe trucks.
