I really love the car but today it would not start on either fuel, it cranks and fires but won't start, it is as if someone is switching the key off again just as it fires, eventually after 15 mins of trying and an almost flat battery it starts and runs fine, at least it got me home from work, which means that until I can get it looked at I have to go back to driving the VT (Farm machinerylol ) again. I hope it is something simple which can be rectified otherwise I'll be too scared to drive it too far, maybe it is the security system, I've re-set the system with the key pad and turning the ign on and off 3 times like it says in the book but it made no difference.

If anyone has had any issues with the factory Mitsu LPG and knows what the problem may be please let me know. It is a great LPG system and feels as smooth and fast on gas as it is on petrol, it feels as fast as other petrol only TJ Magnas I've driven:D

.....If I can just get it started :cry: at one point whilst cranking the firing order sounded like it changed and I thought oh hell it is the timing belt, but then it cranked again normally and fired then after a few goes it started and got me home.

It might be an ignition problem if it's not firing on either fuel. Are you able to have a look at the plugs, leads, and the distributor?

Also, has it backfired recently?

go buy yourself a new ignition remote.

mums TH had exactly the same problem, at first we thought it was a problem with the fuel system.

fitted an ignition remote and there hasnt been a problem since.

Do you mean the Keypad? (with the red and green buttons) Was your mum's TH dual fuel?
It felt like I'd somehow flooded it, maybe I pressed the accelerator whilst trying to start it on LPG (the memcal won't permit it to prevent backfire)

It is now starting first time every time on either fuel, but it starts on petrol much easier.
When I start it on LPG it fires and starts then the revs drop almost to the point of stopping then there is a solenoid click and the revs rise up to normal again and it runs fine, but today it let me down. I will have to get it looked at, especially if it is going to be an intermittent problem, it could fail to start anywhere anytime therefore being an unreliable car, if it stopped at a traffic light in peak hour I could cause a traffic jam or an accident.

I will have to drive my VT pos:rant: until it is sorted because today at work no matter what I did it would not start. I will get in touch with mitsubishi and Impco, I still love the car to death though:D

Have you got much petrol in the tank?

The car starts on Petrol but if the tank is low it will have trouble picking it up first thing so it will be hard to start.

Yes half a tank of petrol and almost full of LPG, I thought of that and also thought of the fuel pump but apparently it will start on LPG but not as easily when it's cold, but I've found this link which is a good read showing a reasonably simple fix to what seems to be a problem with some TJ Magnas to do with a bad connection between the Immobiliser in the BEM control unit to the ECU causing the ECU to shutdown the engine, I'll post the link as it is useful to know these things because problems like this can cost a fortune when Mechanics can't find what is wrong especially with an intermittent problem which could cause your car to stall at traffic lights or not start. Stupid link won't post, it is titled "stalling TJ Magna" the author is Martin "mpot" Pot (martybugs.net) dated 6th March 2006. Sorry I could not get the link to work but it really is worth reading if you own a TJ Magna.

now someone just mentioned the remote.
the immobiliser is actually turned off by not the actual motion of turning the key, but the presence of the specially coded key in the igntion. well thats what ive been told. maybe your key is screwed. got a spare you could try???
i dunno. its prob not the imm. cos u said it started eventually

sorry mate. the problem was an ignition areal (i couldnt think of what it was called last night) we replaced that and the problem was fixed.

apparently its a common fault with many 3rd gens. and yes it was dual fuel.


you can pick one up from repco, im not sure how much. no more than $100 though.

Yeah I spoke to Mitsubishi today and they said if it won't start it is more than likely the ignition circuit behind the key hole which has information transmitted to it via the ignition key, if faulty it will not start, but mine is intermittent so it is more than likely a bad contact which would explain why when I said "bloody hell" and thumped the steering wheel (Temper Temper:redface: ) it then started.

Thanks for your helpful responses guys, if it happens again I will replace the part in the ignition, it is about $80.00 and you can fit it yourself said the Mitsubishi machanic.
Another guy from Mitsubishi said it is more than likely the remote keypad but I only have one which works the other needs soldering, at the moment I am locking and unlocking the car with the key rather than with the remote keypad, it's more than likely one or the other and both cost about the same but I don't want to waste $80 if it is not the problem.

One question is does the actual key (not the remote keypad) have a sensor in it ? I am assuming it does because I have 3 keys and each one will unlock and start the car without the remote pad, with my VT the keypad and key are all in one, I once had just the key without the pad and it would crank but not fire, you can see the little metal sensor which contacts with a metal ring on the ignition, but with the Magna key it must be internal as it looks the same as any other car key to me with no visible sensors.

but I've found this link which is a good read showing a reasonably simple fix to what seems to be a problem with some TJ Magnas to do with a bad connection between the Immobiliser in the BEM control unit to the ECU causing the ECU to shutdown the engine,

i bet this is your problem.. i fixed a few TJs with this issue

its a super easy fix and sounds just like the problem u have.. forget the dual fuel, the problem above happens to any TJ

Yeah it sounds like it could be that, next time it doesn't start I'll yell out some 'Anglo Saxon' Profanities and thump the area or at least rattle the wires and see if it will start.
I've already removed the under dash section under the steering wheel so I can access these connections to find if that is the problem, whatever is causing it one thing is for sure it is an immobilizer issue, Cheers for the reply Gremlin :) is it the brown wire like mentioned in the article? It will take me some time to trust the car again but once you know what the problem is it's not as bad, I went to the shopping centre today and was somewhat nervous, but she started OK

if it is the problem with the immobilizer, as mentioned before, you can tell easily by putting the car into accessories, waiting until the engine light turns off, then starting the car

if the eng light does not turn off, remove it from acc and try again till it does.

if the car seems to be turning on only when the eng light turns off, then it is the immobilizer connection issue, or a low battery

mine is currently doing this as my battery is dyeing and happens when i don't drive the car for a few hrs.

if thats not the issue, then good luck!

Well my turn arghhhhhhhhhhh!

The Wagon has Immobiliser issues and the Mechanic can't fix it, it has to go to a Dealer for the fix. So tomorrow she gets towed to Preston Motors and hopefully they can start having a look asap.

So $270 later after he checked and recked the LPG he can't fix it, grrrrrrrrrrrrr!

Twas a loose wire in the immobiliser.
