Re: Long crank time when cold?

at first that is what mine was doing on a few occasions. however now thats not the case. today I just tryed jumping the pump connector and jumnping in an starting it up. this should have ruled out the maf sensor.(sorry ford term again!) AFM and relay. next I am going to check the thermo switch for the cold start injector. if that seems to be working i am going to yank the upper intake. i have a feeling it might be so carboned up its causing injectors be sluggish for lack of better theory. with talking with some of the old timers around the shop this seemed to be a issue on the early fuel injection engines.

also should note the engine has 198600 miles on orginal engine. PO did some head work around 113k and timing chain and guides around 160-170k i think but thats about it.
