Hello I am new here hope I can get some help.

My io does not start after driving for short /long distances. In order for it to start I have to start it minutes afters after I stop or wait at least 1 hour before I can even think about going anywhere. My mechanic told me its my ignition coils however I have doubts about it. Reason: when it a actually starts it works just fine.

If its of any help, when I turn the key in the ignition I get a ticking sound. Did anyone have this problem before and can offer some advice?

Does it have anything to do with solenoid?

Cheers

.

What model io, engine, do you have? It could be several problem. When you say it doesn't start, does the starter motor turn? or it is completely dead (nothing happen when you turn the key), except that ticking sound?

If it is completely dead you probably have an electrical fault....

A bit out of my comfort zone, but these questions might help other to help you...

A visit to the dealer could be a good option as they have all the equipment to check for pass and existing fault in the ECU.

Happy io

It's a LRXC model io. That should help a little bit.

It's is a 4g94 engine . When

It's is a 4g94 engine . When the key is turned I get a reaction from the engine. Sometimes it will 'turnover' but then cut off. It feels like the gas isn't getting to where it should go.

Does the clicking noise occur every time you turn the igntion on

If it does, it's probably the throttle positioner system, and I believe it's normal - there's at least one other thread on the forum about it.

These vehicles use what is sometimes called "drive-by-wire" meaning that there is no direct connection between the throttle pedal and the throttle plate - it's done by electronics, and on my car, and a few others I've looked at, when you switch on the system seem to "calibrate" itself by opening & closing the throttle plate a few times.

With regard your problem - we need to define exactly whats happening - 'turnover' to me means the engine cranks - you say but then cuts off, which makes me think that you mean the engine actually fired or started and then stopped.

Is your vehicle GDI or MPI (it will say GDI on the body and on the engine cover if it is) - the fuel systems are very different.

the ticking sound only occurs

the ticking sound only occurs when i dont start the vehicle for awhile. I honestly dont think the ignition coil is the problem as the vehicle seems to recieve power as normal. A faulty coil wouldnt give you vehicle full power, based on whatt i read.

My io is GDI. Yes by turnover i meant it starts and then cuts off.

You may have multiple issues.

Does your ticking sound occur before the engine starts or after - many Mitsubishi engines use hydraulic valve lifters which can become noisy, and the noise usually shows up for several seconds after the engine is started, it's more of an annoyance than anything else (and this is also discussed in other threads).

As far as ignition coils go, a GDI engine will have four, one per cylinder and it is unlikely that all will fail simultaneously - you're going to need to troubleshoot this as a no start when the problem occurs - remove a coil, connect it to a spare pluc and see if you have spark would be a good first step.

Just as a suggestion - locate the cam postion sensor (behind the head, on the back of the exhaust cam) - and the next time the problem occurs, use a wet rag to cool the sensor - I know of other makes of vehicle that have had similar symptoms caused by faulty cam position sensors.

Does the check engine light work?

Does your check engine light come on with ignition and go out shortly after (yellow light, looks like an engine in the bottom row) ?  If it stays on you need to get the codes read to determine what fault the ECU has logged.

I just realised you're from Grenada, based on that and your model code, I suspect you have a used JDM vehicle - good luck getting parts for that in the Caribbean.

Thank you Fordem. I will try

Thank you Fordem. I will try out your suggestions and reply. Yes, it's very difficult to get parts here. However, I order all my parts online, if I search and happen to get it here the price is ridiculous.

I ran a diagnostic test and it returned no errors except the catalyst and o2 sensor which I just replaced so that's no more. The person who had the jeep before me did not treat her well at all.

Do you have a particular source?

Is there a particular website or online store that you use?  Some parts are available locally (here in Guyana), but for quite a few I have been cross referencing other Mitsubishi vehicles and then picking up what I need from the US auto parts chains.

There's quite a bit of stuff available from ebay,co,uk, but not everyone will ship to the caribbean.

My suggestion is that you start your own thread and provide the details of your vehicle AND the symptoms you're seeing - whilst it is possible that you have the same vehicle and the same symptom, in my experience, that does not happen very often.

In that case - start answering the questions


Does the check engine light work?

Does it come on when switch the ignition on, and go out when the engine is running?

Are there any error codes set?

Have you tried cooling the cam position sensor?
