Question about Mitsubishi Montero Sport

1 Answer

Dear Sir, My mitsubishi Nativa glow plug burns out in just few months time. I have replace twice the entire set of plugs in less than 30,000 km. In fact I have done only 45,000 km and now again I have to change the burnt plugs. Power 12 volts to plugs remain ON for approximately 12 minutes after the engine starts. Do you think this 12 minutes is correct or do I have to adjust the timer on the control unit. If I need to adjust the timer, please let me know how I can do this. I am a professional electrical engineer and can adjust it on your instructions, Thanks Yunus

SOURCE: Nissan vanette not starting from cold

My vanette had exactly the same problem yesterday. The glow plugs have a timer and a relay. I think that if the light on the dash goes on and off as normal then its probably the relay not the timer. So I have replaced the relay (£50 nissan dealer only) which is located in the center console below the radio/heater controls. Until its really cold again tomorrow I wont know if its really cured it but I'm fairly certain that will be it.

this is a common problem for these cars glow plugs go bad like spark plugs however the smoke would lead to bad mass airflow meter. it is not telling ecu corrcet miss. disconnect mass airflow meter. when cold see if this makes it start better. it should would means you need new m.a.f. glow plug issue take a test light place clamp on positive of battery then pull off glow plug connectors place tip of test light on glow plug the bad one will have a dull light unlike the good one which will be brighter. will need new plugs and wire harness four **** connectors and wire striper and crimper will fix concern good luck

SOURCE: Skoda Octavia Ambiente 2004 1.9 tdi, automatic

problem one is the timer control for the heaters ,also check the heaters that they are working ,oil problem ? look under the rubber boot that goes over the oil switch ,pull it back and if oil under the cover renew the oil switch,these motors do suffer from heater light flashing on and i know people have spent megabucks trying to cure it ,its a fault with dash and printed circuits ,but the heaters are not coming on i know because i have driven one with the heater circuit light coming on and i had a extended light on a long wire and the heaters are not coming on ,ignore it just renew the faulty glow plugs,as for EGR valve just pull teh vacumn pipe off the ERG valve and leave disconnect ,more hassle than its worth changing it ,you could end up with a ECU computer .Still a nice reliable motor though and economical

Possibly is your glow plugs, best to change then all yourself if you can with just a ring spanner and a deep seated socket. Also not enough power in battery to heat plugs up in first place can be the cause. When deisels have been started a few mins, usualy start without waiting for glow plug to go out.

SOURCE: My focus tdci 1800 ran fine until recently. I was

This is one of them faults thats very difficult to diagnose but if what you say is right then i would change the drivers door lock ,they are repairable as they are a sealed unit on these cars,but i did have a similar problem with a petrol version on one of the first models of these cars about a 99 or 2000 as i remember and it would play up just like this ,open and close the door lock with key three times and it started.then be ok for a week then not start again so i had the key man down with his programmer and he checked it out for the key remote and found nothing wrong with either the master or the spare key and he said try changing the door lock because he had this problem before with other ford focus models and mondeos .Change the lock and it was ok for a week but the owner sold the car for a new car on the scrappage scheme so i never did find out it was ok after that

Glow plug burn

It sounds like the timer is not turning off the glow plugs as is should. At least not consistantly. You may want to cycle them several times and verify they do turn off every time.

Just need instructions on how to change the spark plugs and wires

Spark Plugs Spark plugs ignite the air and fuel mixture in the cylinder as the piston reaches the top of the compression stroke. The controlled explosion that results forces the piston down, turning the crankshaft and the rest of the drive train. The average life of a spark plug 30,000 miles (48,300 km). On the 2.2L (LN2),engine the life of the spark plug is 100,000 miles (166,000 km). Part of the reason for this extraordinarily long life is the exclusive use of unleaded fuel, which reduces the amount of deposits within the combustion chamber and on the spark plug electrodes themselves, compared with the deposits left by the leaded gasoline used in the past. An additional contribution to long life is made by the High Energy Ignition (HEI) system, which fires the spark plugs with over 35,000 volts of electricity. The high voltage serves to keep the electrodes clear, which suffer less pitting and wear compared to breaker point ignitions. Fig. 1: Breakdown of a common spark plug 86812008.gif
Fig. 2: Heat range on spark plugs explained 86812006.gif
Nevertheless, the life of a spark plug is dependent on a number of factors, including the mechanical condition of the engine, driving conditions, and the driver's habits. When you remove the plugs, check the condition of the electrodes, they are a good indicator of the internal state of the engine. Since the spark plug wires must be checked every 15,000 miles (24,000 km), the spark plugs can be removed and examined at the same time. This will allow you to keep an eye on the mechanical status of the engine. A small deposit of light tan or rust/red material on a spark plug that has been used for any period of time is to be considered normal. Any other color, or abnormal amounts of wear or deposits, indicates that there is something amiss in the engine. Fig. 3: Explanation of the spark plugs numbering system ---
Spark Plug Wires INSPECTION & TESTING Every 15,000 miles (24,000 km), inspect the spark plug wires for burns, cuts, or breaks in the insulation. Check the boots and the nipples on the distributor cap. Replace any damaged wiring. General Motors requests that you replace your spark plug wires every 30,000 miles (50,000 km). The resistance of the wires should be checked with an ohmmeter. Wires with excessive resistance will cause misfiring, and may make the engine difficult to start in damp weather. To check resistance, remove the distributor cap, leaving the wires in place. Connect one lead of an ohmmeter to an electrode within the cap; connect the other lead to the corresponding spark plug terminal (remove it from the spark plug for this test). The following chart gives resistance values as a function of length. Replace any wire which shows a resistance over 30,000 ohms.
  • 0–15 in. (0–38cm): 3,000–10,000 ohms
  • 15–25 in. (38–64cm): 4,000–15,000 ohms
  • 25–35 in. (64–89cm): 6,000–20,000 ohms
  • Over 35 in. (89cm): 25,000 ohms
It should be remembered that resistance is a function of length; the longer the wire, the greater the resistance. Thus, if the wires on your car are longer than the factory originals, resistance will be higher, quite possibly outside these limits. prev.gif next.gif

I have a 1994 2.8ltr Diesel (4M40 Mtr), Delica, that conks out

try changing all the heater plugs there are warn out by now,,if it realy dont like starting up on cold days do what i do,,, give it twice the heat up time,,,,,
turn on the kye wate till the heater light go's out then quikly switch it off and turn it back on for a re-heat before trying to start it up,,,also try changing the glow plug heater relay,, it should hold the glow plug heaters on for about 30 seconds after the light has gone off even if the engen has started and is running
but i bet its not doing this? giving twice the heat takes less out the battery than cranking it over and your not wearing out the starter as well?
doing this to my old girl gets her going every time!!!!!

97 chevy suburban 6.5 turbo only at 40 or below it trys to cut out ,when the engine temp. warms upon the it runs good new injector pump 30,000.ago and new glow plugs last year with control box if sets over...

It sounds like your some of your glow plugs may be burned out or the glow plug system may not be cycling like it should. Pick up Haynes Diesel Engine Repair Manual, part #10330 at your auto parts store and it will walk you through diagnosis and repair easily and inexpensively.It costs about $20. Hope this helps.

Glow plug problems. Engine won't start.

Did you ever find a solution to this? I have a 2000 Hyundai Galloper (basically the same car) and I am having the exact same problem. I have replaced the glow plugs 3 times in the past 12 months.

Accent 2001 won't start after driving for only 100km

you may want to see if your catalitic converter is clogged up. I had a car that had that problem, when you drove too much it would die and wouldn't start for a long time after that. I had the converter replaced and now it drives just fine. May not be the same problem but it could be. and most muffler shops will check for a small fee if not for free.
