The engine is a 87 supra (non-turbo), swapped into an 85 4 runner. Wired up per the directions on this site...

If you start the truck with MAF and intake elbow hooked up to T.B. the truck runs extremely rich- to the point your eyes are burning from the black smoke from the exhaust. It doesnt run smooth at lower rpms, seems ok at higher rpm/ when revved. I have changed the F.P. regulator, plugs, wires. No help. Any ideas??

I have discovered one additional concern... the fuel pump trigger wire from the MAF doest seem to be working. I have to jump the COR relay w/ 12v to get the fuel pump to turn on (jump the keyed 12v to the fuel pump wire.) I cant imagine this is boosting fuel pressure to the point where it is running so rich, but it may be possible? I pulled the top of the MAF off to make sure it was functioning and it seems to be. There is so much excess fuel in the exhaust I have to think this is an easy fix... but what to fix?? I am open to any ideas, links, or even WAG (wild ass guess) at this point.

Thanks!
