Here's the fuel pump page from the '93 manual:

check your fuel pump pressure and I'm sure you changed your fuel filter. Blow compressed air back through fuel line as it may be something floating in tank. Does flow change when gas cap is off? Is this 20 or 22R motor?

Toyota engines have a built in TSTV- thermo controlled vacuum system where vacuum is applied to the choke system in various levels as according to the temp. of the engine. If the TSTV is faulty or if the vacuum pipes are incorrectly placed then you have a choke which is not opening up properly. Fuel is thus not burnt completely and due to the incomplete combustion there is a formation of soot on your exhaust. Try to get the choke to open up in relation to the temp of the engine. The fuel/air ratio alse needs to be checked ( idle mixture control) once you have the vacuum system working properly.

You replaced the starter, plugs, wires, coil, battery and distributor. That should take care of the spark and the start. My only other guess would be that it isn't getting fuel all the time? Could be a fuel filter or pump. Good luck.

I've had the same problem with my 22r.
I just put silicone gasket ( the stuff you get in the tube for automotive) on top of the o-ring.
It added an extra seal plus also hold the o-ring in place when putting the oil pump back on.
Never had a problem with the oil pump after that.

have you tried changing the fuel pump relay under the hood? it may be old, and the cold could be having an effect on it.
