Default 1993 F350 7.3 Turbo will not start

I just recently got this truck ran great had to do a few things to it. Drove it 20 miles home noticed oil needed to be changed about 3 years since the last change mileage was ok about 1000 miles over but 3 years since last oil change (Going by the date on the filter) had to adjust the brakes someone had do a brake job and did not hook up left self adjustor. I drove it a little over 20 mile shut it off sat for about an hour. Will not start now pulled fuel line out going side of filter output was about 4oz in 30 seconds or so pulled injector line no fuel to speak of eye drop. I think it is injector pump others say no! Any Ideas?

sounds like the tank switch isnt allowing fuel through or your lift pump ( wich is below the vacuum pump on the passsenger side of engine ) ... either one could do it ..

Could not be either one of those getting fuel through the filter. Disconnected the output line from the filer held my thumb over the fitting had someone crank for about 10 seconds stop and crank again stop I let my thumb off got compressed air and fuel so lift pump is working and no flow back so everything is ok though the filter.

Cracked pick up tube is a know issue as well.... Is the tank full ??? Put in more fuel to find out if that is one of the issues, any fuel leaks anywhere ??

Can not be that either I am getting fuel up through the filter so the lift pump is working. I pump my thumb over the fitting and It compressed the air that was in there followed by fuel when released. Got to remember the lift pump only puts out around 5 PSI new so it is possible to hold that much pressure back with my thumb.

No Smoke The only reason I posted here was I was getting different answer from different people and was second guessing myself. I had it figured as something to do with the IP I do have an unrelated question There is a plug on the left Finder well I thought was an ORD1 PLUG (given the year) a quick trip to my Autozone & $30 I get one for a ford. But the Plug is not an ORD1 or ORD2 My question is what is it? Now My 91 F-250 gas 351W does have an ORD! set up And my 97 Exploder has ORD2
