1985 fb starting problems
 

Hi ive just bought a 1985 rx7 fb 12b which hasnt been used for 3 years. ive had it running but it got nice & warm & then cut out, now it wont even fire. the plugs & leads will need changing the fuel is stale so ive added a couple of gallons & some carb cleaner to freshen it up.
the electric hatch & fuel cap do not work and ive traced the feed back to the relay under the bonnet which clicks & has power going in but none coming out.
can someone suggest a good parts supplier and someway of getting it going again. ive pulled the plugs and un flooded it and im not sure what else to do!
