04 V10, crank no start

Hello everyone,

The touareg has sat for awhile as it needed new camshafts and was waiting for Colt to have them ready. Then I was too busy at the shop to get to it.

Anyways, the cams are now in. I will be making a video on how to install them in the near future.

However prior to the vehicle sitting it would start. And make a heck of a ruckus as injector 2 was not being held down.....
I took the cams and lifters out as they had very pronounced wear. I replaced the cams and lifters (without pulling the engine).
And have them all timed correctly.
The vehicle will not start at this time though. The rear battery is not great. But even with a heavy duty charger on the jump post, battery under seat or rear.

The engine cranks over strong. There are a couple of codes, but none that would prevent starting.
ECU 1: glow plug module 1 electrical malfunction. 17054, Cyl 3 glow plug malfunction 17057, Glow plug indicator light 19456
ECU 2: Fuel temp sensor a g8116567, glow plug control module 2 18362.
Immobilizer shows no codes.

The engine will crank over until I stop it.

I have primed the fuel system with the lift pump and ensured that there is lots of diesel there.
I have no smoke at all out the tail pipe.
Using VAGCOM I see RPM in both ECUs.

However using VAGCOM I see that none of the injectors are being triggered.
I have cleaned the ground points at the base of the windshield (both of them).
But I am now at a loss as to why these are not being trigged. I have gone through the engine wiring diagrams but cannot see any information in there that tells me as to where any potential ground points are on the engine block that I may have possibly disturbed.

Any help as to where to look next would be greatly appreciated.

Sorry but I won't be much help at the moment. I have the information you are looking for but it is on my PC at home, which in is Melbourne, and I am currently touring around Mt Isa Queensland, which is 2,600 km away.

Maybe somebody else on the Forum with access to ElsaWin can chime in with the data you need.

hedditch,

Which document on ElsaWin should I be looking at?

I have found a few threads on ground points. And have scoured the manuals looking for them. But none of the manuals I have gone through actually say where the ground points are.

I should also mention that while I did remove the hoses off of the fuel pot. I have confirmed that they are on the correct way as well. :P

After studying the SSP for the V10, as well as a few other documents, I am wondering if a plug from the fuel temp sensor could have been switched with the water sensor for the fuel bowl and if that would cause a no start situation.....
I will know in the morning.....

The plugs for the water sensor and the fuel temp sensor cannot be reversed. 2 pin vs 3 pin.
