ECU problems

[P S K]

Evening all!

Have some issues with feed to the ECU. Pin 52 should have 12 Volts, but for some reason, it doesn't !

Does anyone know where the feed is from, I've got wiring diagrams and have found a drawing of the 19 way connector, which apparantly has a white wire which is the I need to find, to check if that has voltage.

Car was in for MOT tomorrow, looks like I'm going to have to cancel.

According the diagrams it should come from the immobiliser Pin5 (Ignition ECU).

Also, Pin 16 and 7 of the 19-Pin Multiway Connector should be interconnected. (Pin 7 going to Injector Supply)

Thanks for the reply Peter.

I did wonder if I have a problem with the immobiliser!

Although when I de immobilise the car, the red led on the socket next to the silver key goes out, but I get no MiL light and no fuel pump prime.

Spoke to Carl Baker yesterday and he recommends replacement of the whole alarm system

Do you know where this connector is? Searching in the dark and rain last night was no fun!

Thanks

OK. Quick update. Turns out the immobiliser is naffed. Won't put on here what has been done, for security reasons, but car is now up and running again.
