Attach a fuel pressure test gauge to the test port, then cycle the ignition key on and off (without starting the engine) leaving the key in the on position a few seconds each time until the pump has reached its highest reading while the pump is running. This would be 60 to 66 psi for the 4.3 engine or 41 to 47 psi for the 2.2 engine.
try looking at it
lack of fuel check fuel pump pressure and air filter
Ignition coil? Fuel pump? Check for fuel and spark
Your fuel is low. Its telling you to check your gas gauge...
U check 2 C if U have 12 Volts @ the fuel Pump & hope the pump hasn't burnt up from running out of fuel.Then U check 2 c if U have fuel pressure @ the FUEL Rail with a correct fuel pressure Tester.IF U press the schrader valve U COULD get fuel in your eyes.SOMETIMES U will pick-up ALL the TRASH with the FUEL filter-so CHECK 2 C if the filter is clogged.
check fuel pressure and check for clogged fuel filter. if all goog scan for codes
Check for a blown fuse or defective fuel pump relay.
check your fuel pressure.
check fuse for fuel pump or may need a new fuel pressure regulator, its on the fuel rail.
Part of the pump module in the tank.
check to see if fuel pump is coming on check fuse for fuel pump turn key to run and listen for the pump in the tank check relay
check the crankshaft sensor or the cam sensor.
