fine but randomly after it starts it will
lose signal to the injectors everything
from the fuel pump to the injectors
are fine. But the electrical signal to
the injectors will randomly stop and i
am trying to find out why
Are you loosing injector main power or injector driver ground from the ECM. If your loosing main power it could be the ignition switch, if your loosing injector driver it could be the ECM, do you have any codes?
Cam and crank sensors, egr, injector or throttle control sensors if equipped
Stalling issue solved!! in this case it was throttle position sensor!!!
