94 1 Ton turbo diesel won't start

[Tomar]

RETURNED FROM VACATION .Took the truck 'noticed it was starting alittle harder than usual.But after the initial start it would start like normal.Came home and checked the lift pump and it was working as of a matter of fact I opened the bleader on the filter and it was pouring out. Let the truck sit over night and went to start it the next day 'turn key wait for glow plug light to go off and then turned to start' runs for a second then shuts down. Had spare fsd ,tried that ,does the samething.HELP.

Take a clear tube, put inplace of the return line from IP, see any air bubbles? Do the same for one of the injectors.
Have fuel tank full,any change?
Blead filter slowly with clear tube attached,any bubbles?
My truck always has vac.at the fuel cap when I refuel. If I had a line leak it would suck fuel back to tank with air being induce to the system.
