Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for your question,This is not an answer but instead an information request so please hold off on any rating.Are you getting injector pulse?Has the timing belt been checked to make sure the timing belt is turning the cams?Is the computer setting any fault codes?
Post back when you can and we can work from there, I'm here all day.
Okay if your sure you have injector pulse, was the engine checked for spark to the spark plugs and if so do you have good spark?Has a compression test been done and if so what here the reading?What kind of fuel pressure are you getting at the fuel rail?
One last question, dose the check engine light com on with the key and go out while cranking the engine?
The check engine light should illuminate whenever the engine is not running but the key is in the run position. If the check engine light does not illuminate with the key on when it doesn't start, it suggests that the PCM is not being powered up by the PCM power relay, or that the Vehicle Reference Voltage (VREF) signal is shorted out feeding the Throttle Position (TP) and Differential Pressure Feedback EGR (DPFE) sensors. Why don't you try unplugging the DPFE sensor and see if the light come on and if so, see if the engine will now start. See the DPFE location in the link below.

If the check engine light is not coming on then you need to check for power to the PCM from the PCM relay.
That would sure keep it from starting. There are two fuses that power the PCM relay, one is located in the interior fuse panel and one is located in the under hood panel, start with checking to see if they are not blown. See the wiring diagram in the link below for reference for the power to the relay.

Okay then check and see if you have power at the relay on the wires shown in the wiring diagram. Have you checked that and if so do you have power at the relay?
Did the fuses hold after replacement and does it now start?
