7.3 started ran for a min then knocked and died

Ok this morning I started the truck and it cranked right over. It was running for about a min but did not sound right. It started to knock and slowly started to stop running before it died. Thought I might be out of diesel because I was really low. Got home from work put in 2 gal and let the fuel run up. Would not start but sounded like it wanted to. I opened hood heard a high pitch sound from the GPR or maybe even the AIH relay not sure but one of them. Tried about 8 times to get her to start but no go. Did not notice any unburned diesel coming out but did not look to hard.

Help!

Thanks

Well I know one time I had to put at least 25 bucks worth of fuel in my truck to get it to crank after I had ran it low...a little too low. If you get any air in the lines by running it out of fuel and its cold out side it will be a biatch to get cranked back up. However you said you heard some high pitch noise so I guess this is just a bump

How cold was it outside, the high pitched squeal may have been the fuel pump. Is it possible the fuel gelled in the tank.

It was about 34 overnight not as cold as it had been a week ago. I was thinking that maybe it could be the cps. I had mine replaced by the dealer last summer due to the recall letter. I have run my fuel down to the level many times without any problems, my gas indicator showed about an 1/8 of a tank and I have been much lower, but I dumped 2+ gal in anyway thinking wow maybe I'm dry. The night before she drove home like always purring like she does.

Could be the pump.

I would scan for codes and see what you come up with.

No did not check the filter yet it was cold and dark but will do this on Saturday. I can hear the fuel pump so not sure if thats the problem. Only way to pull codes is to get it to a shop and that involves a tow. I guess 1st step is check filter, 2nd drain any possible water, 3rd replace cps, 4th cross fingers and hope one of the 3 work
