Thread: Puma Owners: non-start issue

Failure to lock vehicle with the remote
No security warning light flashing
Central locking not working (depressing drivers door lock would not activate other door locks)
On attempted starting, engine would fire & then cut out & alarm would sound.

Hope this will be useful to others if something similar occurs. The part has not arrived at dealer yet, so I am hoping this diagnosis is correct.

yep your getting your module changed and although mine did exactly the same thing EXACTLY the same..couldn't find anything wrong with mine there for not a problem..

I just hope it doesn't bloody do it again

Yeah Dullbird

Sounds like your's just played up for a bit. I was told but Southside LR that radio interference can be a problem with the remote. Perhaps it was such an issue in your case??

Unfortunately mine went dead. I even pushed it about 20 metres further away to get away from any potential radio interference...but no good.

Hard act to follow

Yeah maybe, I wish I knew, the car has been parked in the same spot for the last 3 months..

and the difficulty of the locking started in a different location the night before around 80klm away from where the car actually decided not to start

Do you reckon there might be any way that the engine immobilizer function can be totally removed?

I'd swap anti theft security for start reliability in the bush any day. I understand mechanical things...but computerized ecectronic stuff I can't, and it's specialized repair anyway, so even if I could, there's no chance of fixing it myself either!

I dont know be good to find out though....

I may be wrong, but I thought immobilisers were required in all new cars from a few years ago. They will also affect your insurance.

My vehicles are old models and don't have immobilisers.

Since my bushie doesn't have doors, let alone locks, and because it has an electric fuel lift pump and the fuse panel is convenient to access and not labelled, my diy immobiliser uses a number of fuses that have been doctored (so they look good but aren't) - I pull appropriate fuses and put them in a safe place, and fit the dummy (immobilised) fuses. To a thief it would appear to be an immobiliser, but they wouldn't know what to hotwire to get it to start and run within a short time. I may fit an audible alarm and motion sensors when I can get around to it.

Is it wise to divulge that sort of info on here John?

You never know who could be watching.



To play it safe, can you let me know which fuses they are?









Please .
