Question about 1990 Mitsubishi Mighty Max

1 Answer

95 Mighty Max has been sitting for one year

Can't get the truck to start. Sprayed starting fluid in airtake, it runs for about 3 seconds then dies. New battery, new fuel filter, new spark plugs and wires. There was about 1/4 tank of old gas in the tank but I recently added fresh gas to 3/4 full now. Truck has been sitting in garage for about a year. Please help if anyone can!!!

Unfortunately if all you did was dilute the stale fuel you will have to remove the entire fuel system and clean/replace.Stale (old)fuel becomes acidic and works like an acid.If you remove the fuel system yourself avoid getting it on your skin as it burns(personal experience)At least its not an ignition fault as the engine wants to run with an independant supply of fuel(start fluid)Sorry cant supply cheap alternative but there you are Good luck and let me know how you go with it.

    Seen this problem regularly on dual fuel vehicles(LPG)as most customers only use LPG because its cheaper to run vehicle and when they eventualy switch back to petrol because the LPG is playing up the vehicle will not run due to stale fuel corroding and destroying fuel pump,fuel lines,injectors/carbs and seals.

Mitsubishi Mighty Max 92 needs to be trouble shot. Started up after sitting for an extended period of time, what parts were affected. It dosnt want to shift or drive really


I recommend changing out your transmission fluid, make sure you replace the screen too. After a vehicle have set for a long period of time it s good to flush all the fluids if you did replace them prior to the vehicle being stored.

1988 Mitsubishi Mighty Max 2.0l auto 120,000mi will die and takes 30 - 60 mins to start?


You would need to figure out if you are dealing with a fuel problem or ignition problem to proceed.
Checking the fuel pressure and for spark at the plugs when it will not start is a good place to begin.
Could be a relay or a long list of other things.

1998 Buick Century wont start. It's been sitting for a year. Battery was dead.I replaced battery, drained fuel, replaced with new fuel and Sea Foam fuel treatment. Will start for a second with Starter...


You have a fuel starvation problem, fuel pump, pressure regulator, injectors, any or all of them could be the reason why you are not getting fuel. Someone is going to have to lay hands and eyes on the thing and check it out.

I have a 1987 mighty max truck that has been sitting for years. The motor turns over but wont start unless I pour fuel into carb. Where do I start to make this truck run again?


I expect the carb has become heavily fouled, old gas will quickly gum things up. I'd drain the tank, add new fuel and rebuild the carb. Also insure you have fuel to the carb (possible failed fuel pump)

If I may help further, please let me know,

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,
