It sounds like the distributor is in 180 degrees off put #1 cylender to top dead center on compression make sure when distributor is put in rotor is in #1 position here is the fireing order

here is the tune up procedures
2.4L and 3.0L (12 Valve) Engines
See Figures 3, 4 and 5
For the timing adjustment procedure on these vehicles, you will need a jumper wire approximately two feet long with alligator clips on both ends. You will also need a paper clip. Make sure that you have these items on hand before attempting to check the timing.
Drive the vehicle until the engine is hot; the temperature gauge indicates normal operating temperature. Apply the handbrake and put the transmission in Neutral (manual) or Park (automatic). Turn off all accessories.
Stop the engine and connect a timing light in accordance with the manufacturer's instructions.

Trace the wire that runs from the primary side of the ignition coil to the noise filter. You will find a single terminal harness connector between these two points or locate the engine speed detection connector-refer to the illustrations for location on your model. Insert a paper clip through the connector on either the female or the male side where the wire enters the connector, do not separate the connector. The paper clip must make full contact with the surface of the connector terminal and must be inserted at the proper angle or you will not be able to get it out.
Once the paper clip is in place, connect a tachometer to it.
Start the engine and check the idle speed. Adjust as necessary.
Stop the engine and turn the ignition switch OFF.
Connect a lead wire with alligator clips to the ignition adjustment terminal (refer to the illustration), and ground it.
Start the engine and allow it to idle.
Illuminate the timing marks on the crankshaft pulley with the timing light. Basic ignition timing should be between 3-7 BTDC.
If the timing is not as specified, loosen the distributor mounting nut and turn the distributor to the right to retard the timing or to the left to advance it.
Once the timing is set to specifications, tighten the mounting nut, being careful not to disturb the distributor.
Stop the engine and disconnect the jumper wire from the ignition timing connector and ground.
Start the engine and run it at idle speed.
If the tune-up specifications on the Vehicle Emission Control Information sticker in the engine compartment of your Mitsubishi disagree with the specifications in this section, the figures on the sticker must be used. The sticker often reflects changes made during the production run.
Check the timing again with the timing light. The timing should be 8 BTDC for the 2.4L and 15 BTDC for the 3.0L (12 valve) engines. This is called actual ignition timing. If the timing is not exactly 8 or 15 , do not be alarmed. This value may vary depending on what mode the computer is in at the time the base adjustment was made. If you do not see a change, check the base timing again. If the base timing is correct, the engine is in time and no further adjustment is necessary.
The ignition timing may vary from the specification even under normal operating conditions and is automatically further advanced at higher altitudes.
