Won't stay running

[Robert Thomas]

Engine has 115,000 miles on second IP, sat for 5 years in the barn. Changed filters, oil, batteries ran great for 200 miles. Driving home it lost power and now won't keep running. I replaced the fuel filters again and the fuel pump to avail. When it does run briefly, it has blue smoke. Should I replace the injector pump next?
Thanks for any advice.

Are the injectors getting fuel at all? Check the fuel return line from the IP to see if it is clogged or dented / kinked? Checking the lift pump probably wouldn't hurt either. Could also be air in the fuel line if there's a crack or hole somewhere... Does it just turn over or does it sound like it's almost catching?

Sounds a little like the pump that brings fuel to the injection pump "aka the lift pump" might be bad??

You can check it by cracking the bleeder valve on the fuel filter and cranking the engine over.
