GM fuel pumps are really easy to diagnose.

Back at the fuel tank you will see a harness that goes to the fuel pump. There will be two grey wires, one black, and one purple wire. The larger grey wire is the power supply to the fuel pump. There should be power on it for 3-5 seconds when the key is turned to the run position and anytime the engine is cranking over.

If there is power there and you have no fuel pressure than the pump is bad. Take a rubber mallet and hit the center of the fuel tank while somebody cranks the engine over. If the pump starts to run you just confirmed that it is bad. Hitting the tank is not a repair. Usually it tells us that the brushes are bad or the commutator is worn out in the pump. Hitting the tank will jar the pump just enough to getting it working in most causes.

If you have no power to the pump let me know and I'll get you some more info on what to check. It is rare to have other issues.

My problem is i have a ford focus 2005 2.0L the main problem is the fuel injector doesnt give any signal so that the fuel pump can supply gasoline... can u please send me a color coding of the wiring...

it is not in the computer box, (PCM). It could be the fuel pump relay if you can't hear the pump run for 5 seconds when key is turned on. It could be your crank sensor not sending a signal to the PCM. Is check engien light on? What happens if you spray startting fluid into the throttle body? Does it start then?

1997 Chevy K1500 Z71 Chevy fuel injector problem

Did you check fuel pressure to make sure you are getting proper fuel pressure? If it will start with starting fluid then it has to be either fuel related or electrical. Are you getting power to your fuel relay? When you turn the key on can you hear your fuel pump come on? I would not use anymore starting fluid at all to try and start it other wise you cause major problems.

I was driving my 99 grand am out of my drive when it died. Like some one just reach over and turned the key off. Cranks real good just won't start. Need all the help I can get.....

sounds like fuel pump quit. It is electric and is in gas tank.
Have someone turn key on while you listen real good at fuel tank area. It shold buzz for 2 seconds & stop. If no buzz, hit bottom of tank with a rubber mallot or something similar. Try to see if pump runs now. If yes, debris getting stcuk or startting to fail.
