Re: car still won't start
The taurus is equipped with what is called a PATS (passive anti theft) that wont let the car start until it recognizes the key in the ignition, some things to check, first when you put the key in and turn the car to run (not start) does the theft light blink fast in the dash or is there a red on light on the dash that starts blinking? if so it is a PATS problem, the only ones I know of that can program keys are dealers, if the car wont turn over it probably is not a fuel pressure issue, the most common thing would be the PATS keys either unprogrammed or somthing wrong with the module. hope this helps

You need to figure out what you do not have that an engine needs to run. What is the fuel pressure at the fuel rail? Do you have spark when cranking the engine? Are the fuel injectors operating? Do you have ample compression? When you figure out what you do not have, that will tell you what you need to fix.
Is it driven daily? Has it been sitting? The more information posted, the better. With this information.....out of fuel, blown fuse, fuel pump, timing belt, fuel filter, dead battery, etc. Does it turn over? Does it try to start but don't? Does it start and die?
I would check the starter for voltage first - there is a starter relay that is grounded by the PCM. If the ASD relay is faulty the pcm won't have power. You should have battery power to the starter and power on the solenoid when you turn the key to start.
I don't know much about these but on my daughters 1.0i polo I had to reset the throttle with a computer after disconnecting the battery for a while. If you are sure you have a spark and fuel getting to the plugs then the fault will lie with timing and fuel mixture.
It sure could be. But, first...by "won't turn over" you do mean it cranks at normal speed but won't start? A simple test of the fuel pump is to stand by tank and listen as someone turns key to on. When first turned to on, your pump will activate for 2 or 3 seconds, pressurizing the fuel system, and then shut off if the engine computer doesn't get a cranking signal. Do you hear it come on? If not, then something's not turning your pump on. If you can hear it buzz on briefly, then maybe it's your filter. Another test: Spray a little starting fluid into your intake manifold (remove the big hose going into intake manifold) while someone tries starting it.If it doesn't fire and try to stay running, then it's probably an ignition problem. But if it does fire off, then you know it's a fuel problem-likely your pump or filter. good luck.
check your fuel pump or your relay that controls the fuel pump if it turns over but cranks and cranks it's possible you aren't receiving gas . When you turn the key on you should hear the fuel pump pressurise if not i would check it first.
Try banging on the fuel tank, and then quickly try to start it, if it starts your fuel pump is almost dead and will need replaced soon.
If it doesn't start, test for power at the wiring connector on top of the fuel tank. This test requires 2 people, because the fuel pump is only powered for a few seconds when the engine isn't running. If you have power, then the problem is in the fuel pump (completely failed or bad wiring connection on the pump/inside the sending unit)
It sounds like you probably have a shorted battery cell. This will not only cause the repeated clicking that you described, but it will also rob power when jump-starting from another vehicle. There is probably enough power when jump starting to turn the starter over, but after the starter take the power that it needs, there is not enough power to operate the computer system....so I have no doubt that you probably are not getting any fuel. The computer has to tell the fuel pump to run. If there is no power for the computer....I think you can figure it out from here.
