Really by the way you describe it you need to check the fuel pressure. There is a valve on the fuel rail for testing it. You will need a fuel pressure gauge. It should have 55 to 65 psi. It will not run on less than 50 psi. If you have less then it will be your pump. Good Luck

The fuse is actually a Relay Switch and its located in the Fuse Relay Center on the driverside of the engine compartment. The Black Box is labled Fuse Relay Center, the diagram on the cap displays which Relay is the Fuel Pump relay...the Relay switch is usually $8-$15 depending on where you shop
