Engine Performance problem
1996 Chevy Tahoe V8 Four Wheel Drive Automatic 220000 miles
1. What should the fuel pressure be when the key is turned on, motor not running.
2. What shoulg the fuel pressure be with the motor running.
3. Does the fuel pump stop running with the key in the on position engine not running after it builds pressure in the system
I have no codes, no miss fires show on hand held scanner, truck sputters going down the road under no load, when you accelerat it runs fine stars hard once and a while.
