Here I test the fuel pressure in my 2004 Tahoe with the flex fuel engine. Everything from locating the test port, relieving the system pressure, hooking up the gauge, and turning on the pump is shown. Also shown is several ways to turn the pump on which could come in handy when tracking down the cause of an inop fuel pump.
Coming up, I'll go more in depth in the fuel pump relay circuits to aid with fuel pump diagnosis. Be sure to subscribe for future Tahoe videos.
Looks like the fuel pressure tester that I have linked in the past has gone up in price a little.
