long hot starts

[Jarrod B]

the ipr has been swapped, had it scanned and seemed fine, random rough idle, and hpop swapped.


whats left to check?

I keep seeing IPR O-rings over and over again on other forums.

Was the IPR swapped with a new one with new O-rings?

[Jarrod B]

they were not broken and looked fine. and no the rings were not new.

If it was a 6.0 I would say HPOS leak. But 7.3 leads me to IPR

Check your battery voltage after driving it for a while.

An alternator going bad will actually suck power out of the batteries while running, so it could be that.


Also, the next step in the line is the CPS.

i think i had it replaced. and i have a spare on my desk .

but the crank speed is just as fast if it was starting right up.

well i changed the cps from one i had left over from the obs. ill see how that does. then this week ill get orings for the ipr.

[Jarrod B]

ok cps didnt improve any.


however, after i placed my order at taco hell, turned the key to on and heard rapid clicking and the dash lights went with it. can a bad relay cause long cranks?
