93 mitsubishi diamante, starts runs for 5 mins then sputters out. cant restart for about 10 mins, then same thing. replaced fuel pump, fuel filter, rotor, dist cap, new plugs and now im lost. and cant find anyone to read trouble codes because its 1993

Has it been sitting up all winter? If so, you might need to drain fuel from the carb and replace the filter. It sounds like a fuel problem to me.

Fuel filter and/or fuel pump.

Sounds like the module inside the distributor. Have to be replaced.

check the pump pressure,what year

when car dies check for spark if you have no spark check the igniter and coil as well as spark plugs cap and rotor

check for 12v constant at your fuel pump if you are not getting that replace your relay.
if you are getting 12 volts at your fuel pump the fuel pump is possible to run tuel it gets warm then shut down to a lower rpm I would then replace the fuel pump

check the relays for the computer, possibly the computer

If that is carbureted, and has a mechanical fuel pump, try running a length of fuel line from inlet side of pump to a gas can that has fresh, clean fuel, and if it runs good that way, you know problem is most likely in the tank. Removing the tank & cleaning it out is best solution from there. I'd even be tempted to add a small bottle or 2 of Lucas Fuel Sytem Cleaner to first fill in clean tank, just to help clean lines as well as carb.

sounds like your fuel pump is bad, it will sputter or be hard to start because there is no pressure. if it doesn't start have someone hit the fuel tank from the bottom while you try to start it, if it starts right up then you know you need a new fuel pump.

Check and change your fuel filter if that doesnt help then your fuel pump will more then likely be the culpret
