Another TD5 won't start

So he's my beef...

I parked the 110 up in a car park and came out an hour later. It turned over but refused to start. It didn't even cough splutter or fart. Not looking too good seeing as my mates 90 just left on a pickup truck as water pump bearing collapsed and had stripped the belt.

Plugged in Nanocom and had a poke about. RAC turn up plug in there diagnostics and poke about. Nothing obvious - ABS & air con. Probably because there not fitted.
ECU is not immobilised.

Fuel pump can be heard running thus relay & main relay must be ok.
No oil in ecu plugs or rocker cover plug.
There was some water in the tray below ecu

but ecu and wiring dry.
Fuses all seem ok.

Since it has come home on a flatbed :
Crankcase sensor changed.
New fuel pump & filter (+plus tank cradle and retaining ring) all bled up. still nothing.
ECU has been removed as is currently with the Royal Mail heading to AliveTuning for bench test.

If the ECU comes back ok where next:
Check crankcase voltage 2-3v
I saw something about starter motor arc causing injector problems. But not sure what to look at or do.
Replace ECU loom
Replace injector seals
Swear at it and give it a kick

That's been nearly a month since she went off the road. Working in the dark is no fun and most time has been spent waiting for the correct parts.

Smell the engine oil, if it smells like diesel it could be the injector seals

Also if it is higher on the dip stick than normal it could be a sign 2002 90 Td5 Station Wagon

I don't have an answer, but am having starting issues with my TD5, and there are a number of suggestions on my thread here http://www.defender2.net/forum/topic25184.html

Mine is intermittent, so haven't had chance to find a fix, although I'm leaning to an electrical issue...a bad earth to the ECU is one I want to check.

Hey Simon
With your issues does the engine turn over? If not then it could be the solenoid contacts for the starter. Look up Denzo in fleabay. You can replace in situ but I found it easier to remove the starter.
A bad ecu earth can cause the temp gauge to do funny things. Reading cold unless parked and handbrake on.

My oil seemed ok but seals don't cost to much. I just need the idiots guide.

Ruari,

Mine turns over just fine (at good speed), fuel pump appears to be running fine and everything else is OK....it just doesn't fire - but only sometimes. Most times it fires OK, and this evening as it was idling on my drive, it died when I got back in the car. But then it started immediately afterwards.

Very strange....

Cheers

It has been mentioned in one of todays papers (the Daily Fail and NO, I don't read the Daily Fail, someone sent me a link, OK?) about the latest "clean" (bio) diesel causing running problems,they were suggesting biocides.

How are you getting on Simon with your repairs

You certainly do hear more and more of supermarket fuel killing cars. Apart from blocking filters I heard it's the ethonyl used to make the Bio that perishes the rubber. So fuel pumps etc die. What is it they kill on the TD5 - injector seals?
It's hard to go to the shell garage when Asda is 7p cheaper!

Tuesday Alive will be testing my ECU.

Ruari,

Its been OK-ish for the last week, but its now waiting for some new exhaust parts, so haven't driven it today. So nothing new to report.

As I said, its either off or its on, no rough running or miss-firing, so I'm still inclined to think its an intermittent electrical connection somewhere.

How is yours..?

cheers

The ECU has been tested and is all ok.

PLan of attack is to re-charge the battery run-though the purge system and give it another try. If this fails then a quick attempt at bump starting.

If that fails electrical test -
Double check earth wires and wiring to starter motor
Does the fuel solenoid stay live whilst cranking - a simple light bulb on the supply. If not new solenoids.
Is 2-3v present at crankcase sensor - so needles to pierce the wires and attach multimeter. If you un-plug the wires it cuts the engine cranking.
Does ECU get power on pin 33 of black plug - could it be the retro fitted immobiliser playing up?
Finishing off with the injector loom.

After that I'm looking at spending money on ECU looms
Fuel filter head
Injector seals
Fuel regulator

But before that happens 2 weeks of eating & drinking.
Have a good festive period folks

Check the starter!

If it idles not fast enough it will not fire up. This may be caused by worn brushes or (more common) by worn solenoid contacts. We (and others) have a contact replacement kit to cure this. WANTED:

I'm fairly certain you can but will stand corrected if not, but can you get the motor on a diagnostics box and turn off the immobiliser to try and eliminate 90% of what could be a problem. A quick thing to check might be to replace the batteries in the key fob, there are mighty peculiar problems that can occour with the damn things, just because it may turn off the alarm it might be immobilising before you actually get to try and start. Just a thought.

Starter had new contacts last year. I now wonder if ecerything was tight???

Nanocom says ecu is not immobilsied but it only reads the 10AS. There is another retro fitted unit which is fubar. But if it was working it wouldn't crank and alarm would sound. Either way if i check power to pin33 then i will be able to check if it is being immobilised.

No faults showing on nanocom other than ABS & air con, luxuries i can only dream of.

At last the Christmas period is over and I'm back at home to look at into the problem.
Last night I re-purged the fuel system. Still nothing.
I removed the rocker cover and replaced the injector loom, still nothing. A bit of oil in the injector plug which I clean out best I could.
But I found that one bolt for the rocker assembly was not even figure tight and a pivot for the rocker is working itself loose
