Here is a roundabout answer: spray a flamable such as carb cleaner or starting fluid into the throttle body-(f/i?) and then crank it. Other wise, hook up a fuel pressure gauge and check while cranking.

How can you tell by troubleshooting if your problem is the fuel pump?

pressure test line comming from fuel tank,one of two ways,1.disconect line from fuel filter on side where fuel line connects from fuel tank,if pressure 26psi to 35psi reconnect line to filter and check your line on other side of filter if pressure holds your fuel pump and fuel filter are ok,the other way is to disconnect inlet line from tank to fuel regulator and check your fuel pressure,the only thing with this method is if your fuel filter is clogging or clogged you will not get an accurate fuel psi.you can also check your fuel regulator,you fuses,or your relays to anything that has to do with your,depending on what type of car you have

What will stop fuel from flowing through outbound reserve line...no pressure. when there is still good pressure and fuel feeding up from the fuel filter line on a 1990 300zx n-a?

Well, i suppose if your injectors are using all of the fuel (super rare) then there would be no fuel coming back to the return fuel line. However, since you say there is NO fuel pressure, I would check out the fuel pressure regulators and the vacuum lines connected to them. The pressure regulators are located on the top of the engine and are directly in line to the fuel line. They are connected between the fuel rail (where all the injectors are fed from) and the metal fuel rail on top.

Is the fuel line pressurized on a 2000 ford mustang?

There is a slight amount of pressure on the line after shutdown. To relieve the pressure remove the gas cap, and look for a Schroeder valve on the fuel rail. If there is none and you want to change the fuel filter, just be prepared for a slight spray of fuel when you disconnect the fuel line. A rag over the connection when you disconnect the line will prevent a spray of fuel.There is a slight amount of pressure on the line after shutdown.

How do you and where to check the fuel pressure for a 2.4 engine?

It depends entirely on the year, make and model on how and where you can check fuel pressure. In order to officially and properly check the fuel pressure you will need a fuel pressure gauge and a set of adapters and fittings that typically come in a relatively expensive kit.Most GM, Ford and Chrysler engines will have a Schrader valve located on the pressure side of the fuel line, usually near the fuel rail that houses the injectors. If the fuel line has one of these valves then you can screw on a fitting that attaches to a fuel pressure gauge, crank the engine and see the fuel pressure. If the vehicle does not have one of these valves then a specific, special fitting that comes with part of the fuel pressure tester kit needs to be installed in line on the pressure side of the fuel lines somewhere where the line can be disconnected.
