Question about 2001 Ford Taurus
SOURCE: 2005 ford escape 6cyl. The
The vehicle will have stored in its ECU some DTCs (diagnostic trouble codes) and you need to have these read out out at the dealer or Autozone to give you an indication of what is wrong. This is actually cheaper and quicker than changing things without a firm diagnosis of the problem. The issue you have at the moment is that the ECU has detected a fault, has set the malfunction indicator light /check engine light (MIL/CEL) and has entered 'limp home' mode to prevent possible damage to the engine or drive-line. Once you have the DTCs, (autozone do this for free and can decipher the code meaning) then these will indicate the main area to look at. It is most likely that water got into a sensor connector and this has interrupted the signal to the ECU. If you have the time disconnect each sensor and make sure that the pins are socket are completely dry before reconnecting. When you are happy that all connections are good then disconnect the battery's negative terminal for five minutes to remove the check engine light code from the ECU. If things are well the car should drive normally once the battery terminal is reconnected

I would also check the front pulley as this is what is used by the crank angle sensor to tell the computer when to fire which coil pack .If the sensor or pulley is damaged it can cause random or continuous cylinder misfires.
Make sure the pulley is tight on the crankshaft at that the rubber in between the inner and outer parts of the pulley is not damaged or slipping.also check for any signs of rub damage on the back of the pulley.When the aircon compressor springs into action it places extra load on the crankshaft pulley.Hope you follow.
Let me know what you see.
Hope this helps.......

It does not sound good its possible with that high mileage the engine has internal damage.Also if you did not have the cylinder heads checked by a machine shop that could pose a problem also.We have replaced so many of those engines that i could not tell you how many ive actually replaced.At this point i would suggest that you install a low mileage salvage engine if you want it to be dependable.

Do a compresion check, if Ok then timing chain is ok, try some throtle body cleaner trough a vac. hose while cranking if stars, fuel pump is out, another way if you have no codes the most poss. cuase is your fuel pump, check press is gauge handy
