hard start 2001 super duty
i have extended crank time on this 7.3.
some times the c.e.l comes on with a code po1211/ uncontrolable i.c.p..
while watching pressure and i.p.r. duty cycle i can see the the command for higher pressure, but the pressure does not exceed about 2000 p.s.i..with a 30% or more duty cycle.
the truck runs and starts ok warm. the glow system checks out.there is oil in the resivoir.
cuold this be a bad high pressure pump?
it has good pressure at hyway speeds.
any ideas? thanks for the help.
