90 Suburban Fuel Pump ?

[Bright Idea]

My good running 1990 suburban quit without warning recently. While sitting, the idle came up and then engine died. Trying to restart it coughed a couple of times. Cannot hear the fuel pump in the tank so I am guessing there is no fuel to the throttle body. When I turn the key on there seems to be a click at the fuel pump relay on the firewall but the pump does not appear to run. I am thinking the pump has failed ? could the relay be the problem ? Fuel guage is working fine. If I need to replace the pump, is it best to replace the entire assembly ? Napa has a Bosch pump on the high end of the price scale. Any experience with these or any other for that matter. Thanks

chances are its the pump, you can buy a relay if you want but be prepared to buy a pump also. The stock pump was weak when new, if you have any performance plans for the truck upgrade the fuel pump now so you wont have to swap it out again later. The stock pump for a tpi camaro will supply mor ethan enough fuel and pressure for any tbi build and will cover a stock ls swap also. If you are thinking about a performance ls swap or over 300 hp the 96-01 vortec 350 pump should cover your needs. In either case buy a Delco pump or trusted aftermarket ..not some parts store cheap replacement.

You could check for power at the tank pump connection

I've had good luck with the Delphi brand

Installed a Walbro pump and Aeromotive regulator in January 2011. Both are still working fine.
