Hi
Can anyone assist with a starter diagram for this tip tronic merc sprinter.

We have no crank
Basic checks show relay under drivers seat is being ground controlled by engine ecu(autodata diagram).We have a supply out from this relay.

Does this go elsewhere or direct to starter?
Tiptronic is in neutral on dash.

I have not scanned this vehicle yet just in case i have a straight forward no crank circuit fault.

If anyone could email a diagram or offer start function description that would help.

thanks simon
