After spending hours on my back under my sons car welding the rust bucket up..she now wont start!

I put in some new glow plugs a couple of weeks ago and the glow plug relay could be heard to click and she would start...

Today, connected the battery back up, turned the key and cant remember if the glow plug light came on but waited about 15 seconds and tried starting her with no luck.

Turned key whilst looking at the dash, no glow plug light and no click from the relay.
I do have power to the relay.

The car has done about 169k so is this likely the relay has gone south or is there something I can test to prove it?
The relay has a multi cored cable and plug going to it but Im not sure what the pin out is. Anyone have a wiring diagram so I can try energising it?

Sorted.....

Was welding the passenger floor pan and forgot I had disconnected a switch by the passenger seat and moved switch as I didnt want to damage it.


Turns out it was a fuel cut off switch! :bang:

Reconnected, turned the key and she fired right up.
