Engine Performance problem
2004 Chevy Suburban V8 Two Wheel Drive Automatic 77000 miles
My burb stalled while driving around 35mph, would not start back up. Had about 2 bars on the gas gauge or 51 miles to empty. Check the fuel pressure at the sch valve and nothing. Towed to friends shop, checked pressure at valve by pressing center of valve and nothing, even when turning on the key.
A day later after towing to another location, by buddy unplugged the regulator and plugged back in and he put the fuel pressure gauge and while he started it he noticed the fuel pressure getting stronger after each turn of the key, when the pressure got back up, everything started working. 2 days later all is well, runs normal.
I replace the fuel filter also.
Now the fuel psi is great while running, but when I turn it off it looses about 10 psi in about 10 minutes but starts back up.
I did not want to replace the fuel pump just yet, 77000 miles.
Also, when it stopped it was showing 51 miles to go on the digital gas gauge, so it was almost empty, I did about a gallon in and it did not help.
But now it's fine, any thoughts?
have the same problem?
