Engine Performance problem
1997 Chevy Tahoe V8 Four Wheel Drive Automatic
After the car sits its hard starting. Putting a fuel pressure gage on the in line valve it builds 50 lbs of pressure buy turning on the key switch 3 or 4 time with air only. If you drain the gage and turn the key back on after 3-4 times fuel will come up the line and fill the gage with fuel instead of air. After that the engines starts and runs like a champ until it sits over night again. Why is the fuel line draining all the fuel back to the tank. Is there a check valve not holding some where?
have the same problem?
