Afther I replaced the injectors the car started run a while afther runing this procedure the car dosent start even if i coded the injectors with cantiecar and kkl cable. What should I do.

Hi,

It does crank but it does not start?

Any fault codes present?

yes it cranks does not start...i look on mes at he diesel presure and desiered presure as I crank it rises up to 300 340 and when it reaches the 372 bar value the car is almost to start but does nothing I suspect the injectors that loose presure but i am no sure i need to crank long time to get 370 bar . I took out the injectors and try with the other ones to see if pressure build the same ....and maybe I do something bad with this option to eepron cpu i guess....any opinion...thanks

changed the injectors no pressure at all 4....6 bars....replacement of rai presuure sensor says failed to exectue This procedure must be executed in case Rail pressure sensor is replaced. maybe from this command the ecu map has been changed...and get corrupted?????

Does the low pressure fuel pump work? The pump inside the fuel tank.
