funny,
it hasnt been driven in a few years but your worried about a light on the dash.
I would suspect that you have bigger fish to fry.
Clean all the grounds,
and the battery terminals,
charge the battery.
drain the fuel out, clean the tank,
put in new fuel lines, change the oil and filter,
clean out the aircleaner ,
look for nests,
change the coolant,
inspect the timing belt,
change the brake fluid,
