I have recently acquired a 1993 SC that has a re-man long block in it from Ford that was installed about 20,000 miles ago I am told. The car has had a ton of upgrade done to it *ie performance mods to the engine FMIC s-trim blower raised top BBK headers full exhaust suspension mods and a Lentech trans. the cars runs like a raped ape and will pass everything but a gas station but it has a little quirk that I have not been able to resolve,.... after the car has run for 15-20 min. if you shut it off the car will not restart. Car will crank crank and then crank some more, but will not fire. If you let the car sit for about and hour it will fire right off and run like there is no tomorrow.. I have recently replace the fuel pump module and the FPR due to another drive-ability issue and that has now been resolved. I have checked to see if there were any codes in the PCM but found none, KOEO nor in KOER. There is no check engine light on and I have checked several things in a data stream function of my scan tool and all seems to be normal other then the fuel pulse width, under cranking the fuel pulse width reads 0.00ms, but when the car is running the pulse width reads with in spec. Through all of the research I've done I cant find weather or not there is supposed to be a pulse width count on cranking do to the fact that the "a typical" IDM readings do not display with out the car running... any help or ideas on this would be greatly appreciated..
