If you are not getting fuel at all I think they may be talking about the fuel cut off switch. Below I posted a picture of its location for you and where you see the blue arrow, just push down on that button to reset it. Not sure as to why it would have popped and you may have other problems if it continues to pop. Ford put that in their vehicle incase of an accident to cut off the fuel supply to limit a fire due to gas. I hope this is the "switch" you are talking about and I hope it helps you.....Good luck.

Something is up with my security 99 ford ranger 4x4 6cyl if i turn the key nothing hapens but i jump the starter to turn over engin but ive got no spark or fuel

All your circuits go thru the ignition switch - sure you can have the starter crank by jumping it but with the ignition switch in off position you are not powering the ignition nor fuel delivery system.

Replace the switch.

My dodge stratus has been sitting for about a year with out being started. The battery was dead so i replaced it with a new one. The problem i am having is with starting the car. I can get the car to start...

You are probably correct. It sounds like you have narrowed it down to the two largest major systems involved in engine management. YUP! It most likely has something to do with either the ignition system or the fuel system. The problem is that you must PROVE which system is at fault before you can find out what is actually wrong. That is what is called DIAGNOSIS.

When the car is not starting, pull a couple of the spark plug wires and check for spark while you are cranking the engine. If you have a bright blue spark coming from the ignition cables, the problem is NOT the the ignition system. If there is no spark, then you know that the ignition system needs to be diagnosed.

The next thing to test is to get a fuel pressure gauge and connect it to the test port on the fuel rail and see how much fuel pressure you have. The specification for your vehicle is 400 +/- 34 kpa (58 +/- 5 psi) If the fuel pressure is within this range when the ignition switch is cycled from OFF to ON, then the fuel delivery system (fuel pump, fuel filter, etc.) is NOT the problem. If it is not within this range, then you need to find out if it is being caused by a restricted filter or a bad pump.

There are other parts to these systems that can cause the problem you are describing, but I am not going to get into diagnosing them until you at least know for sure WHICH major system is causing the problem.

I have replaced the fuel pump on my 1994 pontiac grand prix with the 3.1 litre v6. But it does not seem to be sending the fuel to the motor? In the instructions it says something about the oil pressure...

Are you sure that the fuel pump is properly installed? Have you tested the fuel pump circuits to see if they are working properly? Did you also replace your fuel filter? (It could be totally clogged up) Have you checked to see if there is any fuel pressure at the fuel rail or are you just assuming that the pump is not delivering fuel to the injectors? Have you checked your fuel injector circuits for power and for injector pulse from the EngineControl Module? Have you scanned your Engine Control module to see if you possibly have a Crank Sensor or Cam Sensor problem?

The oil pressure switch only keeps the fuel pump running once the engine starts. The fuel pump should run for 2-3 seconds when you turn the ignition switch to the "Run" position to prime the injectors. The oil pressure switch is the problem only if the engine will not continue to run on its own after it starts up.

How do i release fuel pressure to change my fuel filter ?

There is no real need to release the fuel system pressure to replace the fuel filter. All you need to do is take the filter off. The pressure in the line is not significant enough to do anything when the vehicle is not running. When you reinstall the new filter, you will want to turn your ingintion key all the way on without starting the vehicle at least 3-5 times to pressurize the system and feed fuel back into the new filter. If you do not do this the cranking it will take longer than usual, but it will not damage the engine or fuel delivery system. I hope that this information was helpful

Changed fuel pump and fuel filter.. how do I get all the air out of the lines

When you turn the key on, you should have fuel pressure. If not, something is not right. (The fuel pump should cycle for a few seconds when you first turn on the key to "run")

Fuel pump not working

I would check the connection at the Fuel Pump to ensure a good connection, I have seen this to be a problem on several of these cars. Also on the passenger side inner fender area there is a cut of switch on a lot of these models it looks like a knob you can turn one way or the other.

Good Luck I hope this works for you.
