'82 DL won't fire...

Hoping that the combined wisdom herein can help me...I parked my 82 DL
3 years ago, and started and ran it religiously for about 4 months,
then got lazy, and every couple of months went to every six months to
once a year...Anyway, after installing a new battery, the engine turns
over fine, but the engine won't fire and run. It has new fuel, but it
did sit for about a year without being started. I've tried a mechanics
suggestion of starter fluid (spray ether), and it will fire
momentarily, and then still not fire...Any thoughts on the problem and
possible solutions?

 

Start with elementary troubleshooting: determine whether the problem is
with electric or fuel.

Take it from there.

 

Probably corrosion on the fuses or a dead fuel injection relay, unless
the mice ate into the harnesses.
