Question about 1994 Mitsubishi Montero

2 Answers

94 Montero keeps turning over but will not start?

Was running great, then the other day it would not start. Everything turns on and the car will turn over, and over...but does not start. I can smell gas, so I don't think that it is the fuel pump. I am guessing I just need to replace the spark plugs. Any suggestions?

    Thanks, I'll try those.

    Bearb,

    Thanks! That is what I originally thought last night, and I it sit for about two to three hours. I tried again and it still kept turning over and over, over. This was the first time I have ever had this problem and we have had the Montero for 14 years.

    Before buying spark plugs, I tried it again, this time using your suggestion and it sputtered back to life. Does this mean the engine was just flooded, and is there anything I can do to prevent this?

    P.S. It typically does take a little longer to fire up in cold weather (and it was pretty cold yesterday).

    This Montero sounds like mine - just my starting problems happen on a daily basis - when cold. It will start - eventually. Sputters - than begins to run fine and continues to run fine until it sits for 4+ hours and begins to have difficulty again.

Surya,
-your description sounds like the engine is flooded (too much fuel in the cylinders to start)
(smell gas, turns over...just won't spark)

-you did not describe if this is the 1st time....a random occurance and happens regularly

-if it is flooded..which it sounds like it is....then time is your friend to fix this

  • leave the vehicle sit for 1-2 hours (the gas will evaporate)
if you do not have the time...then you can also get it started
  • push your gas pedal 'though' the floor...hold it there...DO NOT RELEASE UNTIL IT STARTS
  • turn the engine over....it will as you said above...over and over and over..
  • hold the key, let the engine crank...after 10-11 seconds release key...as this is hard on the battery and the starter ....DO NOT LET THE GAS PEDAL UP...still firmly to the floor
  • after a few seconds 'rest' ...do it again
  • the engine will eventually 'catch'..ie. the over and over tone will change sounds (almost like a cough-like noise (when you hear it you will know it!!)
  • this is the point that shows it was/is flooded
  • again release key if still not started after 10 seconds...and try again
  • once the engine starts...quickly release the gas pedal...b4 the revs go crazy
  • the engine will sputter, run rough...as it burns up that extra fuel
  • after 30 seconds +/- the engine will likely run smooth again
-if this doesn't work...post another comment...and we can diagnose further
If it works...please remember to FIX-Ya....as anything else actually lowers my rating...I didn't make the system..but please consider the impacts of your ranking.
thanks

    surya-
    -glad it worked... you were on the right path

    -the cause is just age of vehicle...everything doesn't work as 'automatic' as it did

    -to prevent/minimize it happening...esp when cold you might learn to 'prime' it

    -just b4 turning key...give the gas a 1/3-1/2 'shot' 2 or 3 times...this dumps a bit of gas into the cyclinder so that when the spark is provided by the key turn...it has something to fire with...(this absence of gas..is what actually caused your flooding..as when it doesn't have enough gas...it senses it..dumps more in..which can/does occassionally flood it)
    -this is a fiddle/learning process that quickly will become automatic...to the point i had to actually pause think-through the steps to fixing your above problem

    -no other real fix...but this double 1/2 shot solution works (we do it for the lawn mower when we push the little primer bulb b4 we pull the cord)....again we just do stuff without thinking about the why :)
    -glad it helped

    My Montero sport 2000 is doing the same thing... I tried what you said about holding down the throttle but it kind of spits and sputters then back fires when I turn the key off to "rest".... Still no start?? Any feed back will be greatly appreciated.... I'm smelling gas while cranking the motor as well... Also there was a lot of gas in my oil when I checked it....

I have a 90 montero and the brake lights and turn signals stopped working and I have replaced the fuses and can't figure it out.


my 91 Montero did the same thing, I finally traced it to a bad rocker switch for hazard lights. The switch was broken and it messed up brakes and turn signals. Check your switches that they work and rock properly. My hazard switch was binding turning on and off causing a short. Got a new hazard switch that worked freely and suddenly everything worked right. The problem drove me crazy, and I did replace the turn signal lever assembly first, brake switch, turn signal relay. I found dash switches on eBay.

i can tell you its not the fuel pump.if you smell fuel then the pump is working right,you may have a weak crankshaft sensor though which would keep it from starting and running. but its definately not the fuel pump maybe you have water in your gas
