There are so many things that could cause this, my answer is a guess without being able to see the car. Is your check engine light on? If yes, get someone to analyze the trouble codes and go from there. Check your fuel pump pressure. Check for restricted fuel lines, dents, kinks, etc. Could be a bad ignition module that dies as soon as soon as it gets a bit warm. Check for spark. Use a noid light to check injector pulse. Possibly computer. The capacitors leak and erode the circuit board. (AvPro in Florida is excellent at rebuilding them.) Hope this helps.

91 mitsubishi 3000gt seems to idle ok, but has no power and will not go faster than 40mph.

sounds like you may have a plugged up exhaust or catalytic converter. Try removing the o2 sensors from exhaust pipes and see if it runs better. If it was a timing issue it would idle bad.

Change fuel filter

The fuel filter on a 1992 Mitsubishi 3000GT is located underneath the hood of the vehicle. Open the hood and look near the upper firewall on the passenger side.The fuel filter is a black or silver metal container connected to your fuel line.

My 91 mitsubishi gto wont start and strong smell of fuel

Start by making sure you have spark to the spark plugs. If not you may have a problem with the plug wires or coil. It's also possible you're not getting gas to the engine possibly from a faulty fuel pump.
If you change the fuel pump be sure to replace the fuel filter also.

Cranks over but won't start.

Sounds like an ASD relay (auto shut down). Or it could be a burnt computer. Take out your computer and smell it to see if it is burnt. Good luck.
