Sounds like a fuel pressure problem. no flash codes for that year that will tell you anything. make sure the fuel pump is working.

Yes the points on the relays need to be clean. If the fuel pump does not turn on when you turn the key on the relay is bad.

'84 Supra - Alt & Brake warning lights always on


It's possible that the voltage regulator is shot. I don't know whether the regulator is integrated into the alternator on your car, but a Toyota parts counter (call your dealership) can tell you, if you ask them for a new voltage regulator. They'll tell you if it's available separately or if it is part of the alternator.

Rough Idle on 1984 Toyota Celica Supra


You said you replaced the plugs - did you use the toyota platinum plugs? I found out the hard way that even the platinum plugs from bosch or any other kind of platinum plug just doesn't work right. Yes, they are more expensive from toyota, but they can make a difference in the way the engine runs.
