W210 om606 ews/glow - Mr.Emo - 10-09-2018
Hello.
Will the ecu send signal to the glow relay if ews is active?
Ews has been soldered and recoded.
I'm trying to start a 606 in a patrol. Starter relay doesn't get a signal but the glow relay does. Is this normal if the ews is still functional?
Trying to figure out why it won't start.

Managed to fire up the engine yesterday.
Though I had to hot wire the starter.
Anyone have an idea of why the starter relay is not working? It has 12v live on wire and the other goes to the ecu. The ecu should supply 0v to the relay so it starts right??
If something is wrong wouldn't the ecu cut of fuel not allowing the engine to start?
Also does anyone know the fuse size for the starter? Or is it connected directly to the battery?
Thanks!

Maybe the ECU has some kind of neutral safety switch ??

Do you have the 722.6 transmission also swapped in with its control unit? The engine wont turn the starter until it gets the can signal from the transmission that the gear lever is in p/n.

That's probably it then. The car was automatic. And the new one isn't I bypassed the ecu for starter relay and it fires up properly now
Hopefully that won't give me any issues down the road

The original wiring did not have a fuse for the starter.
