Hi all, New here I live in Lanzarote.
I have a 2005 Matiz 1.0 lhd, I went to it the other day and it will not start, it has fuel coming up from the pump, all fuses ok, has spark at the plugs. I've done a few searches on the forum and disconnected the battery for an hour and reconnected it and still not starting. I thought it might be an immobiliser problem, there is no immobiliser light on the dash from what I can see, there wasn't an owners manual with it when I got it so I don't know what lights are supposed to be on the dash. It definately has an immobiliser as I've removed the steering cowling and can see it. Any ideas anybody please.

I'll leave Jasta to give you a proper answer, but I'd be sort of surprised if it was immobiliser trouble if it has spark and is pumping fuel.

Thanks for the reply, from what I believe ( correct me if I'm wrong) the immobiliser cuts off the fuel supply somewhere in the system, I assumed it was probably at the inlet manifold, I checked it had fuel coming from the pump by undoing the pipe connection where it comes up into the left side of the engine compartment, so no idea if it goes into the engine, sorry should have mentioned spark plugs were dry.

Hi Lanzamatiz. It could be the immobilizer. Whilst the engine cranks and the fuel pump is providing fuel to the fuel rail the engine control unit [ECU] is not allowing injector operation. Do you have a 2nd key that you can try? Can you check for any diagnostic trouble codes [DTC]? Is the engine malfunction indicator light on during cranking [symbol is engine shape on display in front of steering wheel].

Hi Jasta,
I tried the other key, but no joy, the mil light doesn't come on at all, I ordered an obd reader yesterday off ebay but things take a while to get out here.
Guess I have to wait until it arrives to see what's going on.

Hi Lanzamatiz the immobiliser system is fuse protected. You need to check if it receiving power so this issue can be ruled out. The fuse holder that needs checking is inside the vehicle located high up under the dash and secured close to the front door pillar on the driver's side. The age of your vehicle suggests it could be a Daewoo M150 model badged as Chevrolet or a Chevrolet M200 model can you advise? I am more familiar with the M200 model and want to avoid misleading comments. Good luck

Hi, thanks for the info, not sure which model it is, is there an easy way to tell ?
in the logbook it says Chevrolet KLAK KH2/122 Matiz
The car is currently in a carpark on the other side of the island as that's where it was parked when it wouldn't start, so I'll pop down tomorrow and look for the fuse, is it a spade type ?

Hi it looks like your Matiz is a Chevrolet M200. The fuses are "Micro Blade" style. You need to get hold an assorted pack which will include 10 amp[red body] and 15amp[blue body] fuses. The fuse holder should have a clip on cover which will need to be removed. The inside of the cover should provide information of fuse uses. Be prepared for contortions to get to the fuse holder which will include lying on the floor and reaching up behind the dash. Make sure you have a torch with you. Removal and replacement of fuses is easier if you use the tweezer style tool that should be in the engine compartment fuse holder. Look for fuses F2 [10amp] and F14[15amp]. F2- 2nd from top, left bank. F14-5th from top right bank. Disconnect the battery before starting. Good luck.

Hi Jasta,
Thanks for that, I'll get a selection of micro fuses as you suggest, as I only have the larger type.
I'll check tomorrow.

Hi Jasta, found the fusebox ok, both fuses are fine. Is there anything else I can check ?

Hi Lanzamatiz with a good electrical supply to the immobilizer and no indicator light on is looks like the unit or the sensing coil is faulty. When you looked at the unit were there any obvious wiring/connection faults?
If everything looks OK dealer involvement is the only way to sort this upset as specialist kit is needed to verify the immobilizer function.
Although unlikely it is possible the fused supply for the fuel injectors is faulty. This fuse is in the engine compartment holder and marked EMS [engine management system]. It should be 15amp with a blue body. Good luck.

Hi Jasta,
Thanks for the reply, I checked the wiring and everything looked ok, I'll check that fuse next time I go down. If the fuse is ok, do you think it would be worth getting a matching immobiliser, set of keys and ecu from a scrap vehicle, would these then work on my car without needing to take it to the dealer do you think ?

Hi Lanzamatiz the type of replacement you mention is covered in the Spark forum and worked well. Let us know how get on resolving this problem.

Thanks for that Jasta, found the post you referred to, I think I will look at the scrap yards here first, if not I'll try ebay.
Thanks for your help, I'll update this post when I find something.

Ok, Got the Matiz up and running again.
I sourced a second hand ecu and immobiliser on ebay, it came with an ignition key, lock and barrel and door and tailgate locks, also a fuse box and alarm control unit both of which I didn't need to install.
So I changed the ecu and immobiliser and removed the old ignition barrel and replaced it with the second hand one.
Car started first time. Fantastic, took less than an hour to do and cost me €100 including shipping. :)
Thanks Jasta for all your help. (y)(y)(y)

Hi Lanzamatiz you have done a brilliant job keeping your Matiz on the road and thanks for providing the information to the Forum. Lets hope others with similar upsets can follow your lead with what is an involved repair. In passing has the vehicle odometer reading altered after ECU replacement?

Just thought I should add that the parts I sourced came from a 2008 matiz, mine is a 2005 and the part numbers didn't match. I guess you just have to make sure that the ecu, immobiliser and key all came from the same vehicle as they are matched and coded together.

Hi Jasta,
Finally got the car home, runs just fine, no change to the odometer reading so everythings great.
