Hola Emanuele,

La bomba solo arranca cuando el motor esta girando, funcionando

Motronics 2.7 or 5.2? F1 gearbox? Does the car have an immobiliser? What maintenance have you done recently?

When you say you have fuel pressure, I assume the engine is cranking(?)

Where do you have “power”? At the coils? At the injectors? At the engine sensors? At the Motronic engine ECUs?

 

If it is a 5.2, it has a factory immobiliser with red and black key fobs.

 

The coils should be ok if the spark plugs are firing. The middle pin on the coilpack plugs should have 12 volts when you turn on the ignition key.

Were you driving the car for a few days (or weeks) after the service?

 

A couple years ago i stored the car for the winter time and after 5 months i couldn't start it anymore. The engine didn't crank at all. After checking everything i found the error in the passenger fusebox. I had an broken cold solder joint within die fusebox, which was almost invisible.
Mayby worth keeping that in mind

 

1) Before you do anything, is there a flashing red LED at the center of the dash in between the two dash vents?
2) If you have a black FOB, push the button, does the car make any beep (two beeps)?
3) Once you get to this point, insert and turn the key, does the starter engage and crank the engine over at a good decent speed?
4) If the car cranks the starter and the engine does not ignite, now check for ...

a) power at the main ECU relay
b) spark at the ignition wires to the spark plug (use a spare plug)
c) fuel pressure at the top of the fuel filter (45-50 psi)

It gets more complicated after this.

 

I think the OP is still having difficulty figuring out which car he has. He told me in PM that his car looks similar to this and has no immobiliser:
