Question about 2000 Ford Taurus

99 Taurus wont start. spray gas into the intake and it will start

This 99 Taurus was starting fine, I let the car sit for 2 months and now it wont start. Definitely a fuel problem because when I spray gas into the intake it will start but only runs as long as the spray lasts. I hear the fuel pump come on with the key, I have fuel in the fuel rail. I took the needle out of the fuel rail where you test the pressure and when the key is on and the fuel pump is running plenty of fuel flows out, PLENTY. There seams to be fuel pressure as well. I removed the needle and put a tire gauge on the fuel rail and the gauge went up to 31 pounds. (I know this is not a reliable pressure test but it's all I had) The car was starting as I said, only sometimes I had to feather the gas pedal while cranking and then the car would start fine. Now it will not start at all unless I spray gas directly into the intake.

    Thanks anyway, but I don't think its the Fuel filter because why would I have fuel? or fuel pressure? or so much fuel flow? if I have a clogged fuel filter? It does not seem logical. If I had no fuel but still heard the fuel pump working I would suspect the fuel filter but that is not the case. I have plenty of flow when I turn the key with the fuel pump running. When I depress the valve stem on the fuel rail where you test for pressure I have pressure, I have flow. I believe a clogged fuel filter would not allow the fuel to flow so freely. I believe it is a fuel pressure issue. Either the pressure regulator, or the fuel pump is not building enough pressure to "pop-off" the fuel injectors. I am a diesel mechanic and I work for John Deere and when diesel injectors do not have enough pressure built up by the high pressure fuel distributor to actuate the injectors then the injectors wont "pop-off" and you get no diesel fuel to the cylinders. I think I have a problem like that. Like I said earlier, the fuel regulator, or the fuel pump itself I believe is the problem here. but thanks anyway .

    I will check for water in the system but the fuel is new, as I drained the tank and started fresh. As I said I definitely hear the fuel pump come on and run a second or two until pressure is built up, and I have fuel in the fuel rail and when I pump it out with the needle valve removed from the fuel rail I did not seen any evidence of water in the fuel, but tomorrow in the day light I will check that more closely. to be honest I think Ford blows, and I have seen nothing but complaints on the Taurus, and the Escort

Check fuel filter.

    You may have picked up water from the bottom of your fuel tank, that is why i suggested to check the fuel filter. Do you use ethanol type fuel? because this absorbs water and causes corrosion right through the fuel intake system.

If you spray something into the intake & it runs,
then you obviously have no fuel pressure, so you
check that & the fuel pump

You not at a loss,your just doing nothing

99 taurus sat for 2 mounths has gas wont start

Has gas where--- in the fuel tank?

Put a fuel pressure gauge on the
fuel rail & see if you have a working
fuel pump,system & pressure,somewhere
around 40# with key on/eng off

I assume the engine turns with the starter

Is the battery any good,start there,can read 12.5 volts
& still be bad

Will it try & start if you spray the throttle body with starting
fluid or carb cleaner

If you have spark plug wires, put an old plug into one wire
& ground it on motor to check for spark

You can have spark but too weak to run motor

Make sure all fuses are in place & good

My car has been sitting for 2 years and won't start. The engine turns over but it sounds like not getting gas. I read somewhere to spray gas starting inside air intake valve. Where is the air intake v

Safer is to use 'carburetor cleaner' which is also flammable but a little less dangerous than using gasoline.After sitting a long time, our modern gasoline gets tired; never allow something to sit so long without adding some 'fuel stabilizer.'If possible with your car, I would drain (siphon) the tired gas out and replace it with a few gallons of fresh.
Really tough starting problems can also be overcome with 'starting fluid' which is pure ether and very flammable.Any of these may require the removal of the engine air filter so the liquid gets into the intake manifold.
Stale gasoline can also gum up the fuel injectors which may have to be removed for service if none of the fluids causes the engine to fire.

99 Taurus wont start unless primed. Fuel pump is working

Check/Change Fuel Filter(s), PVC Valve & Emission Hoses
Gas that sits too long won't fire easily that's why we have to add winterize to our lawn mowers!
Try filling the tank with some high grade fuel cleaner additive. This stuff is like rocket fuel (about $10).
Also add a can of dry gas as you may have a lot of water and water vapor in your system!
Get a couple more cans of starter fluid too. (I always needed at least two to get my diesel running for summer)
Keep spraying and starting (It always took me at least a full can sometimes 2)
When it starts keep the gas pedal down and rev high for a good 5-10 minutes then see if it will idle.
If it still stumbles and falls consider adding another can of fuel system cleaner and/or dry gas.
Don't drain the tank as this usually just makes it worse by letting the bottom sludge stir up.
Never let your gas tank get too low as this will foul up your fuel system and always add fuel cleaner after every oil change (a must for fuel injection and cat. converter care)

Good Luck!

1999 Chevy S10 cranks but wont start

A very common problem on the 99 S10 is a leaky fuel pressure regulator in the intake plenum.What happens is when the truck sits for a few hours or more the regulator leaks all of the fuel in the fuel injection system into the intake air plenum. This does 2 things, 1 it has no fuel pressure when starting and 2 it floods the air intake with raw fuel. Sometimes if you turn the key on wait 3 seconds then turn key off then turn key back on and just turn key to crank starter for a split second and wait 3 this 3 times to repressurize fuel system then crank to start(you will hear fuel pump buzz each time you do this.also you may have leaky fuel injectors. Try to crank engine with the gas pedel to the floor. This will tell the computer to stop spraying fuel trhough the injectors and it will start. Joe ASE Master Tech
