I have a 2009 Mazda BT50 2.5lt Diesel. The problem is that I need to turn the ignition on and off up to 100 times before the engine and glow plug lights come on. Then it will start straight away. Before then, only the red lights come on and the engine will crank, but not fire. Has anyone encountered this before or got any suggestions?
Thanks!

Maybe the glow plug/s are malfunctioning, A Mazda diagnostic will probably tell more than any guess proffered on here.

Hi Possum3.
Thanks for your reply. Mazda don't know. The obd throws no codes. I am hoping someone might have come across the problem before and found a solution.

1 more thing, the glow plug circuit gets no power until the glow plug light comes on.

possible failure of the glow plug relay/timer

The same model Ford Ranger has problems with the Ign switch, especialy if you have several keys on the same key ring. Result non functioning Ign switch, Fords answer too mutch weight on key barrel. End result new ign switch assy.

Welcome to the gang, Treadin_Water, enjoy here and out in the playground.
The ignition area may be the problem but surprised the dealer's poota didn't show anything. I learnt many moons ago to keep weight in the ignition to a minimum for for many moons now have only had to ignition key and canopy locks key on key ring with the push button door opener.
It might also be worth having a chat to a Repco authorised service centre. I find them great.
Keep Safe on the roads and out there.

sounds like an immobilser issue, or similar.
key comment may be relevant also
Edit - a quick search via google shows it's a common problem,, suggest research your exact issue,, heaps of info immobilizer/keys/battery disconnect etc,, cheers

Have you looked looked at the Mazda forum? It's likely you're not the first to experience this problem.

Not all faults will log a fault code, theres too mutch reliance on fault finding by computer these days. Mechanics these days need to know & undestand how each vehicles electronics systems work.

Thanks everyone.
The key weight issue isn't relevant in this case. I found the aussie Mazda forum hasn't had a new post in years (unless there's one I haven't found).
Baz421, I googled my exact problem and found nothing. Could you please post links of what you found?
By the way, I am a motor mechanic by trade, though happily I haven't had to practice it for a few years now!
I will look at the Rangers and see if they've had the 'Glow/Engine lights not coming on' problem.

Make sure you are insured with AAMI. Give AAMI roadside assist a call and a pretty girl will come out and lift the bonnet then drop the bonnet give a smile and problem fixed. That's what the tv advert indicates. Tongue in cheek comment. .

The engine immobilizer is an anti-theft system built in the engine ECU. It prevents the engine from starting without using vehicle's authorized key. This system uses a special digitally coded key or a Smart Key fob. ... It stores the electronic security code or simply the vehicle's password.
To deactivate the anti-theft system use the unlock button on the remote key. Unlock the driver's door using the key and then switch the ignition switch to the on position. If that doesn't work exit the vehicle and roll up all windows, then use the key to lock the driver's door.Feb 10, 2019
This is a problem that aging Land Rovers like to have. Almost invariably it turns out to be a failing relay. More specifically, it's the contacts of the relay and not the coil so the computer knows that the coil has been energised which makes it happy. It doesn't know that the contacts are fried because it only cares about the coil not being open circuit.

Thanks Baz421.
One of your references outlined specifically that the problem is either the ECU or the immobiliser in the car.
Many thanks to you and all other contributors.

Make sure all battery and earth cable connections are good . Its more an auto elect issue than mechanic ! Btw had the same issue with 6.5 diesel GM . Its a maintenance thing . Just diagnosing it !!

One place o start is to get a voltmeter and get someone to try to start it. Measure the voltage being applied to the glow plugs. It should be around 10 volts or so. If the voltage doesn't drop when the glow plugs are on, the relay is probably the culprit. If it does drop, then something else is causing the problem, but you can probably stop looking at the glow plugs.

Good luck a lot to scour BUT there should be good info there somewhere that fits your problem.
