Dead (more sick than dead) TD5 .v2 - Bexley Sydney

[Cameron_Def]

Gday, wow another dead (sick) td5.

This morning, I went out to grab a new globe for the defender, its started first go as usual, ran for 15-20 seconds (putting belt on etc) and then it spluttered to a stop.

Now it will not start again, turns over nothing else.

What I have checked,

- Fuses / relays all seem fine.

- Removed fuel filter, and fuel is being pumped and I can hear the pump (only 10-15k old)

- Put some "Start you bastard" down the snorkel, and it kicks over 1-2 times and once the vapor is gone, it just turns over and over.

- Checked oil in the harness, there was a little, but its been replaced so its just residual, removed and clean again.

Yesterday I did a 120k return trip from Syd to the Gong, all fine, no temp changes etc in the 40d heat?!

What else can I check, I am guessing its a fuel issue ??

Thanks in advance!

Cameron!

can you hear the fuel pump spinning up inside the tank?

dont foget to check the harness plug on the drivers side front of the engine

Yeap can hear the pump pumping and seen fuel run from the filter (rear tyre) and I have replaced the injector harness.

Thanks for your reply.. I am lost :(

It sounds like fuel pump problems - possibly algae in the diesel. When I changed the fuel pump on my daughters TD5 Defender the strainer inside the white outer pump case was completely blocked with a green/black scum.

I am willing to bet that if I would have just cleaned this and replaced the fuel in the tank I would have been OK

Thanks for that I do not think its that, as its a new pump, I said 10-20k ago, but its more like 5-10k.

The pump is pumping, it put 10ltrs in a bucket really quickly, and I usually get my fuel from the same place, and since last fill, I have done 200kms.

If it was algae, it wouldnt have pumped so quick into the bucket I am guessing.

Hmmm! Thanks for your ideas thou!

If it's not the fuel end it could be the crank angel sensor.

The other thing is check your battery is good and not on the way out.

That said it does sound more like the fuel's not getting up the front end.

Have you followed the priming instructions in the owner's manual? Also I'm not sure where else you can break in to the fuel line but if its getting to the filter I'd be checking further forward.

Thanks for that, Battery is fine, its starting to go down now as I was turning it over alot, Yeah followed the priming instructions 3x full noise then start, but it was running fine yesterday ?!

I have some more mechanical minded friends coming over tomorrow, else I will get rovemechanical over asap :(

as derick said, crank angle sensor! i un plugged mine when i did the clutch change, and it was the only thing i forgot when it was all back together... just cranked and cranked...nothing.....

cheers phil

Where is the crank angle sensor ? how easy is it to get too ?

Sorry me and cars are kinda are on different pages of different books :) sorry to sounds like a dik. ;)

[Blknight.aus]

if its not as simple as the front harness plug or the crank angle sensor plug coming off then its time to quickly whip the return line for the fuel system off from the engine and check the fuel coming from there and if the fuel is coming from there nicely then your firmly in the relm of electronic problems.

The crank angle sensor can be roughly checked by placing a led and 1K resistor (that will need confirmation Im a bit rusty on the resistor value and which terminals are which) across the terminals and if the led blinks when you spin the engine over then it shouldnt be that (but it can still be out of range) so that pretty much leaves you with something powering the ECU (or not) or a dead ECU.

I did add a tacho the other day to pin 19, but it has done 500km since that was done, would the crank angle sensor die all of a sudden ?

[Blknight.aus]

yep any sensor can just "let go" at any time with little to no warning.

some of the things that can kill them include.

the back emf of a central locking solenoid not filtering correctly and that spikes something, arcing in the starter motor solenoid, age

its my pet hate of electronic engine management, replacing a sensor is easy and usually the diagnostics tool will even tell you what sensor went and when it went (relevent to ECU hours) but you never know what killed it, did it just die or did something take it out. At least with mechanical systems you can usually identify the cause of death.

How annoying !!

Is the sensor expensive ? Should I have a look in Rave to see where it is ?

Thanks heaps blknight!

cam,
on the drivers side of the bellhousing there is a little white plastic plug with a black plug and wires going to it. thats your CAS. it wont be easy to spot as its hidden under the main harness that crosses the bell housing. eaisest way is to take the bonnet off and have a really good look.

Thanks for that, should I check that its still connected etc ?

[Blknight.aus]

yep eyeball the RAVE it might take you a couple of goes to orientate the Rave pics to the engine but its easier than me going

its on the dohicky near the main crank pully under the alternator and trying to word picture you into the correct location..

dont know about cost I havent had to replace one yet but a quick phone call to four wheel drives down in melbourne M R autos in redcliffe or even justinc (send him a PM) should be able to help you on that.

Hi, I have a spare crank angle sensor out of a D2 which I keep in my spares kit. I assume this D2 and Defender sensor is the same. You can borrow this to see if it is the problem. PM me tonight if interested as I can drop it off tomorrow.

Hi don't if this applies to yours but my TD5 Disco developed a miss that got worse as the engine heated up, I replaced filters, the air mass meter, was at the point that I thought the ECU would have to be replaced so I got the thing on a computer and it turned out the ecu was oiled up causing a breakdown in connection for the injector circuits apparently over time oil is forced down the inside of the wiring harnes that goes from the injectors to the ECU. repair was simly unplug the ECU hold it upside down to drain the oil and clean the contacts with electrical cleaner, I also changhed the Harnes in the valve cover to break the flow of oil for a while. never missed a beat since.

Yeap replaced and cleaned my harness, so it can not be that .. Thanks for the info though!

[Cameron_Def]

And the solution to this, and to my disbelief,

It is the Fuel pump... I know I wrote you all off... but I would have thought a new pump no older than 6 months old and less than 15k on it would die.

Time to cut a hole it the floor, I am not dropping the tank again, thats a pain in the ****.

Thanks again for all your support the forum is a wealth of ideas and information and people who are more than willing to go out of there way to help another person. I applaud you all.

Cameron.

Good news! Really!

All this time I figured that it was a screw wandering around in your valves!

Kidding of course,following lots of TD5 problem threads has go me going!

Mind you all that the crank position sensor is on the Passenger side of the bell housing just behind the fuel regulator (very handy) unless it's the one on my 110 which IS on the drivers side just to the rear of the fuel regulator if it was not a 300.. I carry a spare now.

On a realtive note The fuel pump in my V8i Disco which I converted to a TD5 is the origanal with 155,000 miles. Go figure...
