93 won't start

[dpuckett]

I just bought a 93 D350 with 150K miles from a rental company next door to where my fiancee works. [The truck was used to haul bobcats, etc to people who rented them; IT wasnt rented out]. I did my normal new vehicle service- change all fluids and filters. After the changing the fuel filter, it would not start. Some trial and error revealed a faulty lift pump- line out of it was completely off, and not a drop of fuel coming out of it. I replaced the pump, and still not starting. It will crank, and run for about 1-2 seconds, then die. Fuel is getting to all the injectors. The pump is fairly new, though that means nothing in itself. It is getting juice to the fuel solenoid, though I guess the solenoid could be faulty itself. I am at a loss as to what to check out next. It was running strong (for a stock engine- guages still in the mail) when I got home. I HAD just filled the tank, and driven about 30 miles to home. I have been getting fuel there for a while with no problem (40 gallons a week), so I would put that kind of far down on the list. I have never had any real fuel system trouble before with these enginges. What little things can make it not run suddenly?

Thanks in advance.
