My 1997 7.3 Powerstroke Wont Start

Hey I hope someone can help me....I have a 1997 7.3 powerstroke and i drove home from baseball practice last night and it was running just fine, i went home and parked in by my house and this morning I went outside to start it and it wouldn't start. It would turn over just fine like it wanted to start but wouldn't, there was no smoke coming from the exhaust. The tach. was not coming up so i replaced the CPS and it didnt change, i went to the fuel filter and cranked while i bled a little fuel out of the little valve to make sure it was getting fuel and it was......does anyone have any ideas of what could be wrong.

Does the WTS light come on? If it doesn't, your fuel bowl heater could have shorted out, it's a fairly common occurence, like the CPS. when it shorts out, it takes out the PCM power fuse. It's a 30-amp maxi-fuse, #22 in the underhood fuse box IIRC. How are your batteries?

The WTS light does not come on anymore, and i will see if that's the problem. the batteries are almost brand new along with a starter alternator.
could it maybe be the #22 fuse????

Sounds like the heater shorted out. When it goes, it blows the #22 fuse. If you install a new one and it dies right away or shortly after, there's your problem.

When mine went, I didn't have another fuse on hand, so I took the fuse from the trailer lights (if I remember right), and popped it in. It fired right up and died about 2 seconds later. I replaced both fuses, unplugged the heater, and have been good to go ever since.

If you need to unplug the heater, it's on the lefthand side of the fuel bowl. There should be three plugs. It's the middle plug, about a 1/2" square rubber plug IIRC. I haven't heard of anybody having any issues from unplugging it, nor have I had any myself. Let us know if it works!

Yeah, it's on the outside. Well, the actual heater is inside the bowl, but the plug is on the outside. I asked guys who live all over the country, and none of them said they have had problems. They said you have more of a probability of the fuel gelling in the lines between the tank and the bowl than actually in the bowl.
