Re: EF starting difficulties? fuel?
Hi, sounds like a flooding problem, possibly injectors. the ford eec system goes into flood mode when the pedal is held all the way down and the engine turned over, at this time, no fuel is injected into the cylinders, on the other hand if you crank over a fuel injected engine and pump the pedal, you will flood the motor.
So if your injectors were dribbling fuel when the engine was shut off, holding down the pedal while starting would pump only air in till the mixture in the cyls leaned out enough to fire, flooding in a fuel injected engine can easily destroy sparkplugs, and they may have to be replaced.
Other possibilities could be a wrong coolant temp sensor reading, it should still read around 1.2volts to .7volts after a hot 20minute rest.
Back to the injectors, besides the fact that they might be leaking due to a deposit buildup, the driver inside the processor which controlls them might be malfuntioning, causing it to stay open, not to common though.
I would recommend having the injectors removed and bench tested for flow and leakage, this will tell you if thats the problem, and even if it isnt, it doesnt hurt to get the injectors properly cleaned as regular maintenance.
every injector has a filter that will be replaced at the time of cleaning, and from the ones i've done, a improvement in flow is always noticed after a cleaning.
