I took my 2002 Ford F 250 7.3 Diesel to the dealer for the recall of the cam sensor, maybe coincidence but twice now I have parked the truck on a slight slope nose down and after only 10 to 20 minutes it wouldn't start? The way I got it to start last time I removed the fuel filter. It started right up. Could the cam sensor cause an intermitent problem of this nature?? :mad:
