Could the Iid tool be used to run the FBH in a situation like this?- although it would be better used for what it's designed for and help find the real cause of poor starting, although even the Iid tool cannot test cylinder pressure's.

Shocked but....but.... it starts without hesitation.....

Mind you it's running for a good 40 mins before I drive off in it.

A bit of a follow up on my cold starting problems.

I conversed with Bodsy via several PMs and decided, for the money, I'd give the kit a go. As it happened he was in the delights of South Wales on a Friday so I wouldn't have to wait long. This was a stroke of luck as on Thursday, it was so cold I could not start the car at all and had to get the in laws to drop the kids offat school and I had to work from home.

Anyway, Bodsy turned up on Friday and fitted the kit. It's one of them Altox jobbies and there's another thread on here about them. I suspect I could have had a go myself but I'm pretty sure I'd have b***ered it up somehow. So to me, it was worth getting someone in who knew what he was doing.

Obviously Bodsy made the fitting look easy but there was a PITA factor of registering the SIM card, downloading apps, visiting websites, entering in unique device numbers, phone numbers and passwords. Thankfully he'd done that a few times as well and now all works like a dream.

I had a chance to test it on Saturday morning as we had another cold sub zero start to the day and after 30 minutes of running the FBH, it fired up first time. Personally, that's all I care about. I'm not ripping out a head and having stuck glowplugs drilled out because that's up to three weeks off the road, waiting for the head to be returned from a specialist and the cost is extortionate as well.

I'll give it a month and report back to let other s know how it's working out.

It is still worth getting your plugs and injectors checked. If you are masking a problem it's best to know what it is.

Glow plugs are needed for engine efficiency, throttle response and low-down pickup. They are not just there for starting. Spending money on an FBH remote rather than diagnostics is potentially unwise. Given the reliability of the FBH, unless it has been serviced (unlikely), you are probably not out of the woods just yet.

And yes, I am sure Bodsy was keen to sell you something. Did he test your engine sensors, plugs and injectors?

cold starting

I have a problem starting on cold mornings. Ive been told that its the glow plugs and they are a devil to get them out.
There are people who drill and re-tap them, that is an answer.

I hit upon a method, a bit heath robinson but here goes :-

I put my wifes hair dryer on max speed and heat and placed it under the bonnet on the left side pointing down. into the engine bay alongside the engine. Waited 5 mins and fired the engine up.

I know its a bit of a daft thing but it works especially as the temperature goes down to -1C

Hope this helps (Its a bit cheaper than the alternative).

Tried and tested method. Also if you have long arms and RHD hold the hairdryer drier to the air intake while staring the engine.

Hi my jeep won't start in the cold weather so I thought it was the Glo Plugs which will be a nightmare to get replaced. So I was reading on the forum were I got information on the FBH which I know nothing about other than I think it is actually disabled on my jeep. Why would the previous owner have disabled the FBH? perhaps I won't need glo plugs? Can anyone help?
Thank You

You appear to be lost, you have a jeep but you are asking questions on a Land Rover Discovery 3 forum.

Shocked

Disabled to save fuel, most likely just unplugged or just the can wires removed from the plug.

Ps the word jeep is highly offensive to land rover owners Mr. Green

Ooops I didn't realise that referring to my Landrover D3 as a **** was offensive lol. Thank You for your reply.

Cold starting issue

Constant cold starting issue below freezing
Took plug off coolant sensor and connected a resistor in parallel across the 2 wires through a switch.

Next cold start below freezing pressed switch which fools temp gauge into moving above cold and starts first time

£4 done - works perfect

Tell us what value resistor you fitted in parallel? 😀

Resistor size

5k resistor - press switch and it lifts temp gauge just below half way in approx 6 seconds - it then starts no problem

If you fit a resister to make the ecu think the engine is warmer than it is then surely that will make it harder to start as it will be delivering less fuel the the glow plugs will not operate and injector timing will not be adjusted for a cold start, you want it to think it is colder!
