Hey guys

i have a 2002 F250 7.3L and it wont start. Its been sitting for the past few days in the cold because the batteries were shot but was plugged in the whole time. I replaced the batteries today and even poured diesel 911 5 hours before trying to start it in case the fuel was gelled. It cranks fine but just wont turn over.
Any thoughts???

Thank you!

 

if the fuel is gelled the additives will not do any good in the tank.
the lines and filter will still be gelled.

the only way to eliminate gelled fuel as the problem is to get the truck in a garage or something to raise the temperature of everything to over 40 degrees for around 24 hours to ensure everything is warmed up to a temp above 32 degrees.

 

Might want to post this in the 7.3 forum, And let the Gods over there fix you up.

 

I have a 02 7.3L also that a few winters ago did the very same thing. Towed it to Ford garage and mech worked on it 4 hrs and could not get it to start.

So I picked up the phone and called one of the top Ford Diesel Mechs in I know in SD and put him on the phone with the mech at Ford Dealership. My friend Jerry knew I had a Super Chip in my truck because I told him that and the first thing he told the guy was to unplug the Super Chip and then try it. Walla, Truck started right up! So if you have any modification like that check it out. Good luck
