Hi folks, the new project is a early '99 Ford 7.3 PowerStroke with an oddball problem. Figured we'd check with the Motor heads here - never know who has run across what!
The issue is with the start circuit. 9 times out 10 it will start just fine but that 1 odd time the starter will grind against the flex-plate and not engage. Try again and its fine. The previous owner rebuilt the stater and replaced the flex-plate with no change in symptoms. Apparently it has been doing this since new.
The start system is rather complicated and it is routed through a number of safety checks before the starter is triggered; neutral/park, etc., and all that is tied into a solenoid on the fender that has two legs. One leg for battery power to the starter motor and one leg for the starter trigger. Nothing seems to be wrong in any of this, but something is.
We're wondering if anyone here has run into anything similar.
