Series II faults... Almost too many to mention !!

[AussieDisco]

Hi All

My Series II hates me. It is a 1999 3.9l V8 Auto (Dual Fuel - but currently only running on petrol)

1.On Friday, for no apparent reason it suddenly stopped when stood in traffic and only started again after about 20 seconds of cranking the engine. Since then, it's almost stopped a couple of times and then recovered. It also seems to be down on power sometimes and then seems Ok other times. Am I experiencing symptoms of a failing fuel pump or could it be something more sinister.

2. Also when stood in traffic (not the same time), the two mode lights started flashing along with the LCD display which tells you which gear it is in. When I set off, it seemed like driving a manual car with the clutch slipping badly. This was because it switches to a "Limp home" mode by locking it into 3rd so as to not damage the transmission. Once I stopped it and restarted it, all was well. To be on the safe side, I took it to the local LR garage yesterday and they put testbook on it. The fault code it showed basically said that the computer couldn't understand the signals that were being sent. They cleared the codes and road tested it and the same thing happened again. Same fault code showed up on testbook.

Has anybody heard of similar problems?

Not sure about the D2 because mine is a D1, but when I got mine back from having the front shocks and coils replaced it stalled about 2 k's up the road and wouldn't start again. I called the mechanics who had just tuned it at the same time and they came straight out. It turned out that the connector on the thing (I'm sure everybody else can tell me what it is :oops: ) between the air filter and injector had come loose. As soon as it was put back on properly it started easily and hasn't missed a beat (on road) sisnce then.

I am sure there are a lot more connectors on a D2 that can cause it, so you will probably have fun trying to find them all 8O 8O

MAF plug loose? (air flow meter).

The first fault might be some sort of interference by the gas system. Who fitted it?

Not to sure on the second one though. Matt

[AussieDisco]

Nah, I don't think it's the Gas. It's been on gas for just over 3 years now and the gas converter packed in about 8 weeks ago so to all intents and purposes, there is no gas on it anymore.

However, this is an interesting theory that has just been put to me..... See what you guys think.
The car is now at the garage and they say that they have all of a sudden had several cars in that require new fuel pumps and their theory is that it is the fuel companies messing around with the blend of the fuel

Thats quite a theory don't you think. Of course, it's one thing having a theory and it's another thing proving it.

I normally get all my fuel from Shell stations (cos I get 4c/litre off) but last week, I filled up at one of the independents. I'm not suggesting for one minute that independents blend their fuel. Maybe it's just a coincidence, but with all the hype about blending ethanol with fuel... it kinda makes you start rubbing your chin and going Mmmmmmmm !!

Hmmm, I'd check the fuel filters are not plugged up to be honest. No doubt this will overheat/stuff etc the fuel pumps or cause them to switch off if the pump is also not full of gunge.

Bad fuel and clogged filters causes the down on power and cold running problem.

[Ace]

The filter might be blocked, upon starting the sediment would be settled as the engine runs it slowly builds up around the element, then it dies, the engine is stopped the sediment settles and away you go again. Check the filters and work from there. Matt

All sorted...

It turned out to be the Crank angle sensor that was causing the transmission lights to come on and the misfire/cutting out...

Thanks to the guys at Ritters Automotive for sorting it out.

I am glad it's sorted style_emoticons/<#EMO_DIR#>/biggrin.gif . All power to Ritters 8)

I wouldn't have a clue about my crank angle because I drive a 300 Tdi so did they explain what that meant?

BTW that was a serious question.

[AussieDisco]

The crank angle sensor senses the position of the crankshaft (as the name would suggest). It contributes to controlling a host of engine management functions such as timing, transmision etc, etc.

Forgive me ....I am a luddite....

All those things are connected mechanically...is it a sensor and software issue?

[DirtyDawg]

Silly me I thought crank angle was masturbating in a recliner...doh :roll:
