Thread: td5 not alive

Have you checked the injector harness for oil contamination. Blue plug front driver's side (RHD) of the engine. Even if it's not visible there it would be worth taking the cover off and giving the harness a good clean.

I can't recall what the injector voltage is but you should be able to see it on a meter. Also see if the Nanocom will give the injector voltages from the ECU when everything is running.

Have you got a Rave CD for the TDd5 Defender?

thnks for the reply i am trying to get the rave cd, i will check the harness again, i checked the first day and thats how i discovered there was no voltage at the injectors, will remove and clean, i didnt see how to check injector voltage on the nanocom.

unless youve got a really good meter you wont measure the voltage on the injectors.

they run at about 85V and only have power on them while they are actually injecting which is about one poompteenth of a second. I dont think the nanocom shows you the voltage but it does give you the injector status and duty cycle as a % of the total available rate of injection (Idle is about 3% and full noise is about 100% if its under full load)

If its turning but not starting and you've established that you have fuel pressure (you only need about 10-15psi in the head to get to idle) I would suggest that you check the crank angle sensor (pull the fuel pump relay, ingnition on mulitmeter on the relevent leads of the sensor then crank the engine or turn it by hand, you're looking for a pulsing on the 5v side of the sensor)

You can test fire each injector using the Nanaocom. It will make feint click. At least that will tell you if power is reaching them.
If the loom is the problem a rough clean will be enough to get the motor going, even if it is rough. Blknight has probably located the problem with the CPS.

Cheers.

on the re-read, what fault codes are coming up?.

Is the nanocom powering up correctly?

What about a worn starter motor affecting the crank position signals?

You can buy a new set of brushes from ebay for next to nothing.

When you say you swapped the ECU, have you learnt the security codes via the nanocom to allow it to start?

thanks to all for the ideas, im going to start on it now, i fitted the nex brushes to the starter from ebay about a month ago, so i will replace the starter to make sure, i have a spare in the garage, i will remove the cps to clean and check it, i didnt change the security settings of the new ecu, i forgot i had to do that, i will look up how to do that if i cant find anything else, the faults on the nanocom are the usual turbo wastegate, egr problem, the egr is long gone the wastegate i cant figure out, its been there since i have had the car but i cant see wiring on the turbo for a sensor?
will let you know what i find
my wifes getting jealous the td5 gets more attention than her lately

if its a manual, just try push/tow starting it.. that eliminates the electical interference from the starter motor.
