Beenhaving trouble starting, while starter doesn't seem to be dragging, I think it may have too heavy a power draw. Last time it started, it ran for a minute, stopped and have never been able to get it started again.
I replaced the fuel pump, and added 3.5 gallons fuel to tank (just in case low fuel). Still won't start. Going out to check fuses and fuel stop solenoid.

 

when the engine fires and runs and then stops shortly after,this is when air intrusion is likely the issue.
see,she took off for ya,because of the fuel left in the ip.once that ran out,the filter and line was dry,because the vacuum broke.
searching air intrusion here will help ya out.search "injector install kit" as well for starters.
of course once that's fixed,a simple GP test and a cleaning of all the battery cables goes a long ways too.remember there's two ends to clean of those cables.like on the starter,and the grounds on the block etc.shine 'em right up nice with some sand paper,then put the ol grease right to 'em.the faster these turn over,the faster they'll fire......provided the fuel and gp system issues are resolved.
don't be afraid to put some more fuel in the tanks either.another common issue with these gal's are broken off pickup tube/strainers making them suck air 1/4 tank and less.so start there first.
get out your battery charger,and plug her in(meaning the engines block heater).fill up the fuel filter with fuel/additive etc.it'll all help ya to get ol Betsey resurrected.

 

Gp - Glow Plug?
