My good friend's 2001 with 5.2 liter no longer starts, symptoms suggest fuel pump. The manual indicates an adapter is needed to tee in a pressure gauge. Manual drawings show a threaded fitting connecting fuel line to fuel rail.

Can anyone say the size/pitch of the threads, or a good source for pressure test adapter?

PS vehicle has only 60,000 miles, seems very low for fuel pump failure. Has anyone had similar experience?

Thanks!

 

First off can you hear the pump prime when you put the key to "on" but not start it?

 

On the 01, there should be a pressure port on the drivers side fuel rail, towards the back.....

 

Thank you! Prime is audible. My gauge fits early Chevy, I think threads are the same as a tire valve stem. Vehicle is somewhat out of pocket, lives in the next town. If anyone can say about test port threads it might save some running around.

Thanks again!

 

GM gauge should go right on there. I think they are the same size.
