Mp7 starting issue
in Engine and Transmission
Posted
Hello all I have a 07 mp7 pre emissions that has a hard time starting have to pump the shit out of the primmer pump to get it to start and even after I get it started and let it run I can shut it off and it won’t start again unless I pump it up again so we done everything fuel related from the gear driven fuel pump, fuel pressure regulator, new updated stainless steel injector cups and injectors. Iam at a lost with this thing and need some ideas and maybe someone had had this issue thanks
