Re: 2003 Tahoe 5.3 Flex Fuel Surging at 2000 RPM uphill

so with all the fuel pump issues with these vehicles you "THINK" its not the fuel pump.

these forums have much info about all this ! much info !


no guessing just get a fuel pressure guage and measure the fuel pressure.

If its below 53psi engine running replace it.

that would not be throwing parts at IT . that would be logical troubleshooting steps to determine the engine issues of power loss.

with 170,ooomi or running this type vehicle with low fuel levels this would be what to expect to fail.
