How do I troubleshoot the fuel system

If you get in your car and turn key to on position, you should hear your fuel pump purring in the gas tank for a few seconds. If not check fuse, if fuse is ok you can check fuel pressure at fuel rail where injectors are, if you have a tester. But I think that your problem will be solved with a new fuel pump. If you don't hear the PURR it's time for new pump. GOOD LUCK FRIEND.

Well not start not getting fule

with key on engine off listen to your fuel pump see if it will prime(you are looking for buzzing sound from fuel pump for few seconds),if it does not do that you need fuel pump,if it does then you need borrow fuel pressure gauge from local auto part store and check the fuel pressure,put the key in ignition on key on,engine off you should get between 37 to 41 PSI

1995 honda civic d15b7 cranks but wont start. new

Are you sure you have correct timing? its definetly a fule problem, if timing is good then turn your key to the on position and try to listin for the fule pump to prime. While the key is in on position go to fuel rail, there is a valve on fule rail called sharader valve. Get a small screw driver and press valve in to check if car has fule pressure. if pressure is present then it is incorrect timing or possible bad cam sensor.

locate the fuel pump and see if you can hook a 12 volt source (car battery) directly to it if the pump turns on you know that the pump is not getting power if it does not turn on you know you need a new fuel pump

89 regal won,t start but after 5 or 10 min. runs great

sounds like your fuel pump is going out. One thought might be that the fuel filter is causing enough resistance to over heat the pump. I would check the fule pressure to determine a free flow of fuel.

How to check fuel pressure regulator 1990 300zx na

Multi point injection systems run at about 45-55 psi. When the key is turned on,engine off, fuel pump will run for a short time to prime the fuel rail. At this time the tester should read normal pressure or a little higher.

You need to use a pressure gauge and run it in-line with the fuel lines. Pop the hood and look to the left. Just above where the strut mounts you will see a round silver filter. You need to remove the fuel line there and place your pressure gauge in line of that.

Let me know if you need any more help.
