ok so i changed the fuel regulator and it sisnt fix the problem so i changed the thing that the little brown plug goes into. that didnt do it eaither i pulled the fuel rail and turned the key on and the injectors were out of the rail as well fuel came out of three of the holes for the injectors. i put the injectors back in the rail and turned the key on and nuthing comes out of them and they are pluged in and the regulator and all the vacum lines and i tested the brown plug for power. it has power on one side but when pluged in it has power to both so i guess its ok. but why wont it spray any fuel at all?

ok i was messing with the fuel and i looked under the car and seen a wet spot on the ground. that smelled like gas so i was looking around and seen the feed line was leaking so do you guys think if that line was leaking would cause the problems i have been having?

Do you have power at the injectors? You can put a test light on the plug and see. Use an old bulb and wire from a turn signal or parking light. Then stick the wires in the injector plug, crank the engine and see if it lights up. You'll barely be able to see it since it happens fast.

alternative

I bought a couple of dozen stainless screws on the Bay for my gas tank sending unit.
But as a cheap alternative, before attempting to turn and screw which may be rusted, position the screwdriver tip in the head of the screw and then hit it sharply, straight down, with a hammer. Then turn.

If you damage or need to replace any screws, just pop off any Mazda valve cover at the junk yard and repeat the hammer first, then turn trick. They should all be the same size screws.

Craftsman makes a wonderful little bit set for backing out stripped screws. I don't remember what I paid for mine but I'd argue its worth every penny. Fasteners are easy to replace, just get the old ones out first.

As for the wet spot, I would definitely say it has SOMETHING to do with the lack of fuel. But if the pump is bad that would effect it too.

Did you try removing the fuel line BEFORE the fuel filter and having a buddy try and crank the car? If there's no fuel, its the pump (or Relay, don't ask). If there is gas and its not getting fuel AFTER the filter, then replace the filter. If your car was sitting for a while you could just have some crap built up in your lines.

That's my .02
