1996 7.3 crank/ no start

[STROKER9733]

I know there is a lot of threads like this along the same lines. I am to the point now where i have no what it could be. Was leaving my house Saturday and the truck cranked fine. Got halfway done the driveway and it started rough idle and then just shut off. Wouldnt crank back. I thought maybe I had ran it out of gas and there was just air in the lines, but that wasnt the problem. I had been getting a strong smell of diesel fuel the past couple weeks, and come to find out the lift pump had a leak so I replaced that and the fuel filter. thinking it was the problem. Good pressure off schrader valve. It still wouldnt crank, no white smoke or anything. I checked the icp sensor all was good. I replaced the ipr sensor still no start. The hpop reservoir has oil about an inch from the top and I pulled the line going to the head and it had good pressure. Replaced CPS still nothing. Fuel bowl fills with fuel so I know the pump is working. Changed GPR. I switched IDM from another truck still nothing. I unplugged fuel bowl heater and checked all fuses and tested them. I ran buzz test and plugged in snap on scanner and no codes and everything was communicating fine. Today when I was cranking it I could hear the injectors firing and started to get some white smoke. It fired up for about a minute then cut off. I got home from work and pulled the ts performance chip thinking maybe that was the problem still nothing. Came back out after dinner and now the WTS light wont come on and I dont hear the injectors. Check fuse 22 and 9 and all was good. So now I feel like I am worse then when I started.

I have pretty much ran out of things to check. All I can think of is maybe the pcm is bad. Other than that I have no clue. Please help if anyone has any info it would be greatly appreciated. Thanks

Pop the valve covers off, I bet you have a melted UVCH connection.
