ran for seconds and now won't start

[mbutts]

I have a 1999 F350 with a 7.3L. it started and ran for a few seconds and now will not start. I un-plugged the fuel warmer at the filter and still nothing.. A couple of months ago it died going down the road and it was the 30 amp fuse for the fuel system. I am at a loss, any ideas???

Unplugging the heater is great to do it it's blowing that fuse, but if already blown you'd have to change it first

If the Fuel heater fuse was the problem it would mean the WTS light wouldn't illuminate when you first roll-on the key... Do you have a WTS light?

I did unplug the heater and I do have the WTS light when turning on the key. It did not blow the fuse this time just died after start and never started again. Just changed the fuel filter and cps,,,,, no change

How about fuel?

Is there fuel in the fuel bowl now? (open the drain level to check)

Does the pump run? (are you a 99.5 or earlier?) Fuel refilling filter housing?

Could the fuel gauge be giving a bad reading? (are you close to empty?)

Was the truck starting from a clod start when this happened or was it an restart?

How cold is it where you are? Could there be ice in the fuel system somewhere? Have you tried plugging it in for a couple of hours?

How's the truck been running otherwise?

The fuel bowl does fill up after draining it, I have tried this a couple of time just to make sure. I am pretty sure I can hear the pump running, the bowl seemed to have pressure after trying to start it and then releasing the drain. The gauge reads over a half of tank and has never been wrong before but i will check today.
It was a cold start, that day is had been 4 degrees for two days, I do however always plug it in if it is going to be under 30 because it has never liked the cold.
A couple of times in the previous days it had started for a few seconds and the died but it did start right back up and run fine for the day. That happened twice in the previous few days before it did not start again, if that makes since.

It has been running pretty good otherwise, not much to say there.. I am not sure if it is a 99.5 or newer. How do i find that out??

I recommend pulling the ICP sensor and checking for oil in the connection and make sure the pins are straight and not bent, and make sure that the connector holes are making contact. That can cause it to fire and stall out.
