STARTING

2001 Chevrolet Suburban • V8 AWD Automatic • 130,000 miles

2001 suburban I have cycle the starter three times about 2 to 3 seconds off and on after the car sits for over 4 hours to have the engine fire up. It acts like the is no fuel, but once I go through this procedure it cranks right up and runs fine. I was told that the fuel pressure is leaking down when the motor is off and that on start up if the motor does not start within 2 seconds the fuel pump shuts down to prevent flooding the engine therefore I have to cycle the start three or four times in order to get the fuel back to the engine. If this is true where is the mystery valve located and what needs to be done to correct this problem

Why don't you check the fuel pressure if its within specs with a gauge to rule out the fuel pump and also a fuel pressure leakdown problem-
