2.2 CRD Glow Plugs not getting power

[adamg]

Since I got my 2.2 CRD cruiser it has had issues starting in the cold. I thought this might be the turbo pipe (as car went into limp mode when driving on a motorway) so I recently replaced that (the old one had a bit of rubber glued on!) but it didn't solve the problem.

The mechanic tested the glow plugs when I was starting up the car and he said they aren't getting any power.

I've tried changing over the glow plug relay in the pdc under the bonnet and it didn't solve the problem. Anyone know where I can get new relays from in the uk?

Is there anything else that it could be (like a engine temperature sensor or something like that?)

Forgot to mention glow plugs are new (old ones were the same) and it starts fine when it's warm (eg not freezing) outside or after it has been driven for a while.

just took them off, too big

There is a fusible link in the power circuit from the battery to the glow plugs through the relay.
Fuse #13 in the PDC protects the relay coil circuit; the PDC grounds the relay.

The diesel Fuel/Ignition System schematics take 15 pages, 35-50.

thanks will take a look in the pdc to see if I can spot it.

I changed fuse 13 (see pic for anyone viewing) but its still not working.
My mechanic retested and said that no live is coming through to the relay when the key is turned.
Is there any other fuses that this could be or anything else?

check the fuseable link not the fuse

Ah right that makes sense. I'm not very good at wiring at all. As a rough guide whereabouts on the car Is the power circuit fuseable link be located? Under the seat? Or in the door/ under the main dash? It looks like this might be a job for a autoelectrician but he said he had never worked on a cruiser before and said he couldn't get parts!

The fusible link will be hidden under the tape-wrapped harness bundle that exits the PDC and runs rearward toward the firewall. A thick (6 gauge) black/ grey wire changes to a red wire after the fusible link. The wire goes to a connector near the firewall (left side, black, 4-pin, 3-wires). The fusible link and a splice should be near the connector.
