Thread: Def Td5 start issues

update of issue thus far
starter switch is brand new fitted, car battery brand new
realised i am having problems with immobiliser, managed to track down the EKA code, attempting to enter the code via the ign switch to decode and reactivate the system. the pink relay is not a relay but works well. hoping to get it started soon, changed oil, fuel and air filters so good to go.

I think its definately a immobiliser issue car cannot accept the EKA code sequence in the LR manual. Also think I'm having problems with a starting relay if i can find it somewhere. Found the immobiliser mounted behind the binnacle unplugged one of the two plugs and the red light on dash went out but did not start. If i disconnect both plugs of the immobiliser will it start? Will try this next. Any idea where the starting relay is for the Def Td5, under the driver seat or behind the gear stick main fuse panel? New ignition switch fitted but when i turn over the key, lights on dash come up, can hear the fuel pump prise but nothing no cranking at all with or without the red light 'on' for the immobiliser. Hence thinking could be a starting or ignition relay somewhere. Any further suggestions to try please.

hi,

did the dash light up when you tried to unlock via the EKA code? if not it might be worth trying again.

does the EKA happen to have a zero in it? i believe the zero equates to ten turns of the ignition.

no the dash did not light up when doing the EKA code, i have tried a number of times and have read in the manual that after 3 attempts you are locked out for 30mins.

the last digit is a 0, so thought that meant no turns but will try 10 turns to see if that makes any difference, thanks for your input

So disconnecting the two sockets from the immobilbiser did not work either, made the red light go out on the dash but did not crank or start.
I replaced all 4 pin relays (driver seat base and main fuse behind gear stick) with another relay to rule out the relay issue, no difference.
EKA code did not work replacing the '0' with 10 turns as suggested
Can someone confirm whether i need to apply the foot brake when attempting to start the Td5
Any other suggestions most welcomed.
When turning the key to start position III, lights come up on dash but nothing, no crank, no turning over of the engine, just fuel pump priming, why isn't the starter motor engaging??? Maybe a fuse problem with the starter motor, might check that next.

Don't need the brake on to start a td5 and the AS10 (immobiliser) must be plugged in for the engine to run. ECU talks to the AS10 module.

Really need a diagnostics tool like a nanocom to see what faults are up.

Check the terminals on the starter motor if you haven't already.
I thought the immobiliser deactivated the fuel pump?

Can you hear the starter solenoid clicking with the ingnition?

Thanks

Need to check the starter motor terminals then, that's my next step.
Checked all relays and they appear good, working order
There is a fusible link under drivers seat for ignition, all good there
Fuel pump does prime each time on starter key location III
Key location II does not light up the dash lights as would be normal or expected
Starter solenoid does not click with starting just the fuel pump
Must check the location of the starter motor then and subsequent wiring in that area

Try earthing out the starter motor to see if it is ok, if it engages and winds the engine over you can rule out the starter motor then start checking eletrical issues. I had a similiar issue with my 200tdi hadnt been started in months ignition switch failed, replaced the switch and then found the starter motor to be completely dead wouldnt wind over at all even with a slight tap to the starter.
