May have the valve settings too tight making for low compression and no start. Cranks fast, good fire, good fuel, still no start. Check compression with a gage. Could also have timing on cam incorrect so valves are overlapping too long. Check, check, and recheck all your work. Best thing for a mechanic to do. Keeps away the frustration.

Your choke adjustment or cold start are not working to bring it to high idle cold start.

How many miles?
Could be a bent pushrod.
Could be just a high mile engine that needs overhauld.
Could be you engine needs higher octane fuel...as engines get older and worn they will benifit from higher octane.

I need to hotwire my 1994 Mitsubishi Mighty Max


Unless it has a points and condenser distributor you are not going to hot wire it. Electronic ignition relies on numerous signals to the ECU to fire the ignition and the fuel injectors. Unless you live outside of the USA or in a country without many smog restrictions then you have electronic ignition and fuel injection. If you have points and condenser ignition the run a wire from the battery positive to the ignition coil positive.

After is hot if I turn it off it would not start until is cool


If you have no spark to the plugs when it won't start, it could be a coil or other ignition problem. No fuel could be a fuel pump relay.

You've already eliminated the spark plug & wireset, distributor cap & rotor.
Sounds like your car needs a tune-up, specifically, the PCV (positive crankcase ventilation) valve, and/of the EGR (Exhaust Gas Recirculation) valve.

Components checked/replaced during a tune-up are:
air filter
motor oil
motor oil filter
breather filter
fuel filter(s)
fuel strainer
PCV valve
EGR valve
spark plugs
spark plug wires
ECM or distributor cap & rotor
cabin air filter
transmission oil filter
transmission oil
engine coolant
check all vacuum hoses and lines

Troubleshooting the no-start condition - from the 1990 Mitsu Mighty Max Repair Manual:

91 mighty max wont start when cold


Next time when cold and it will not start remove a spark plug or two and see if the engines flooded. If so there are two things that come to mind; 1, worn injectors, leaking as engine sits with time causing difficult starts 2: bad oxygen sensor, if failed engines tend to run rich and the ECU may have your injectors pump heavy amounts of fuel to keep from running lean; often times you'll see poor fuel MPG if O2 sensor failed.

I hope this may have assisted you,

Just wont spark!!!


Good day
If you had replace all of that, I would check the fuse for you ignition system. Make sure that you take the fuse completely out to look at it. Please let me know how you make out. If no luck we can look into this deeper.

Cheers.
