What have you checked so far ?
Could be a fuel or ignition problem.
The distributor cap and rotor could be bad, or fuel pressure could be low among other things.

1995 mitsubushi wont start and it isint getting fuel and it backfires when trying to start


Backfire can be caused by lean fuel condition. No fuel can be fuse, relay, filter or pump. Check for power at pump and if none, trace backwards. If pump runs, check fuel pressure at fuel rail.
