The fuel pmp may still pressurize the line but may not be generating enough pressure for the injectors. in other words it still pumps but not enough. correct pressure is important in fuel injected vehicles.

You said the fule that came out of the filter was muddy looking, have you checked the fuel in the tank to make sure it was not the same? If the vehicle sat for any length of time with less than a full tank of fuel then condensation builds up and starts to rust the tank from th inside out. This could account for the colour of the fuel and crap in the filter. The filter may be clogged with rust or the fuel may not be clean enough to sustain running. As well, any particles that get past the filter can clog or damage the injectors.

Siphone some fuel out of the tank and check the colour and for particles. I would also change the filter again and cut the old one open for inspection.

If this turns out to be the problem then you may have to drop the tank to clean it right out. This is a more involved process than it sounds but is neccesary if you want to avoid future problems. If this is the case let me know and I can give you some tips on proper cleaning of the tank.
For future reference never store a vehicle with less than a full tank of gas and add fuel stabilizer before filling so that it mixes well.

Good Luck and keep us informed on how you make out.

i'll take a look at it when i get a change..... i have alot to do today...... but if it is the tank, how difficult do you think it would be for someone who's not very mechanically inclined??

The Main relay is a computer chip that control the fuel going into the engine I have 2 of them go out on both my cars and is will not start, but it was fix. The Main relay should be under the steer wheel where the dash is.

Could be the relay but I doubt it. You said you got the car to start but then it stopped again, likely not the relay. The relay is just an on/off switch that is activated by a low current wire that allows the high current wire to send power to the fuel pump (that is the one you are talking about right?) That is the main fuel pump relay, there should also be a main ignition relay. I am not sure where they are but if it was them then the car would not atart at all.

Check that fuel! if it is not clear and smells like fresh gas that could very well be the problem.

If you can change a jet engine you can clean the tank out.

Empty the tank of fuel (siphone or an electric pump)
Undo the straps and lower the tank down gently with a floor jack or a couple of buddies.
When you can see the top, undo the fuel lines and electrical connections for the gauge.
Pull the tank out
Pull the sending unit out and empty the rest of the tank.
Drop and chain in the tank and shake the sh%t out of it to loosen the rust up.
Put soap (dishwashing will do) and water in the tank and shake it up again.
Empty the tank out and flush with clean water, empty again.
You should try to find something to seal the tank up after this, a local shop that does tanks should be able to help you. This stuff will seal the metal and inhibat rust from starting again.
Reintall the tank and fill with gas.

Check the fuel condition first as this is a time consuming process only to find out that it was not the problem.
As well if the fuel was really bad you may need a new pump as well but you can test it as stated in an earlier post.

I talking about the Main fuel relay, before the main relay gave out on mine it will not start for 30min. after 30min or trying, it finally start,but after a week later the car didnt start so i change it and it work fine now, but that just my car.

The main relay should be under the dash on the steer wheel.You dont need to tear out the dash to get to it, but try to angle ur body to look under the dash it should say something main relay.

I think u should just call a professional to take a look at it.

it's been rainy here the past couple of days, so i haven't been able to do much...
i'm going to syphon some gas and look at it to see if it's bad.....

as for the main relay, resting my head against the brake peddle, looking up, is it to the right of the steering wheel?

and for a professional, i cant afford that right now.....

thanks all for your help... i really apritiate it..

thanks,
