Tell us more.

Does it beep?

Does it click?

Does it crank (turn-over, but no start)

Is it really moist/humid & have ground issue?

cranks (very fast,..fresh battery yesterday,.) have it on charger to replace cranking loss
when it starts,... it starts instantly
bright lights
not a real humid area (just got done with -10 for a week)
not frozen (+40 today)
you can go out start it then a few hours later it wont start,.. then maybe the next day it will start. or not

Yeah, I still suspect humidity playing a role. Check the ground on the ECM computer (under seat?). Does your bus/State have corrosion/salt?

Check on a ford forum. A quick search suggests that it could be the crank position sensor. Lots of folks have reported similar issues with that sensor being one of the main culprits.

Yes, fuel pump was another one that seemed to be giving the Ford guys fits.
I know the pumps on the Crown Vics are famous for failing and being a huge PITA.

I know the older fords had 2 fuel pumps, 1 in the tank and 1 on the frame rail. If either one wasn't working they would sometimes run and sometimes not run. P.S. I hate cars.... Try starting fluid for diagnosing.
