Yes I know, but If you hold the accelerator pedal to the floor on a fuel injected car, the Throttle position sensor will tell the computer to enter clear flood mode. Then the computer will shut off the fuel injectors while you have the pedal to the floor. If it is flooded, you should be able to get it started in clear flood.

Check the cam and crank sensors, If no pulse is detected the ECM will not fire the coils. Check your wireing harness at ECM and terminal conectors. Check your ground at coil packs...Last but not least...possible bad ECM.
Good luck...i hope this helps.

Have a test done on the glo-plug system as it appears that they have burnt out and are not pre-heating the cylinders or providing a source of ignition for the atomised fuel from the injectors

Holding the gas pedal to the floor will cause the PCM to put the fuel injection system into clear flood mode , cutting the amout of fuel going into the engine . Pumping or pushing on the gas pedal while cranking the engine over does nothing but allow more air into the engine , it's not giving it more gas . The computer has a set program it follows at start up . It's not like a carburetor ! Fuel pressure regulator .

2001 Taurus won't start when warm. Try to start it, it will try to run, roughly, then dies. Then will only turn over for awhile. After it sits for 20 minutes or so, it starts like a new one and keeps...


Sometimes a motor is more sensitive to warm conditions. When the water temperature sensor does not cool off it keeps the engine in a warm run mode which is very lean. This is how lower emissions and better fuel economy are made.

The "cold start sequence" makes a richer fuel mix for starting and running. I have not seen a dividing point where this switches from one mode to the other. IF it is say 180 water temperature degrees and your car stays above 180 degrees turned off after running, then the fuel mix will be very lean until the engine coolant loses heat.

About all you can do is put in a new thermostat of proper temperature or a lower temperature thermostat. You could flush the radiator and back flush the block so that heat loss is more efficient. You could put in a new water temperature sensor. You want to get rid of calcium-fication of the internal surface areas so the components are more like factory new.

Check fuel pressure, and regulator. A leaking regulator gives a warm engine more fuel [ it does not like it] a cold motor does. same as a flooded motor. Good luck

the common problem on these cars is a bad coolant temp sensor when they start going bad they will read a cooler temperature for the computer than the actual temp some times it is a big difference.and the colder it reads the more gas will be supplied this will flood the car and you will smell gas.the part is cheap.about ten dollars
