My car has not started for 4 days now!! I have strugged to get someone out (bad time of year)! Anyway, got someone out this morning the car engine turns over but does not ignite. The mechanic said that is the fuel solenoid that is not allowing diesel through to the engine. Does this sound correct and if so can anyone give me an idea on cost.

He said that for it to be replaced it would also have to be hooked up to ford's diaignostic computer, again is this the case?
