Hello,
Ford Transit Custom 1995cc 96kW engine YMF6 year 3/2017
diesel
changed 4 injectors because of P126A now it will crank ONLY again and the DTCs are:

P1212:64-64 pressure command injector below threshold

Injectors are original, NEW. Mechanic did not code the injectors.

It start with spray.
There is not a bleeding fuel line function in diagnostic.

What do you suggest?
