Immobilised at pub

[mattrosersv]

Quick Q as car left me stranded at the pub the other night...

Could someone PM me with the location of the immobiliser in the Cerb. Have no fuel pump

Also on my chim the fuel pump relay did occasionally give out - Any idea where I can find the fuel pump relay in the Cerb? - Damn search not working.

Off to the pub now to try and jury rig her home........

Thanks,

Matt

I can think of worse places to be stranded...

I reckon it will start fine this time....
If not are you sure its not the battery?
silver key?
otherwise hot wire the immobiliser

Hi Gazab,
Thanks.
Happened before a couple of times and battery was not fantastic so literally just replaced it. Hmm, have had starting probs with low volts from battery before, perhaps new battery has got the jolt but not the volts - turns over fine.
Not the silver key as it was lost some time ago.
Just checking out wiring diagram now... Suspect immobiliser.

Not sure but I thought immobilizer just effects the starter, i.e. fuel pump going but not firing her up? Same for low battery...

Probably a breathalizer fitted that kicked in after you returned from the pub?

Immobiliser definitely controls both starter and fuel pump - I have the wiring diagram in front of me...

Ignition as well? I thought they had separate relays for each?

[mattrosersv]

Hi TV8 Looks like your right about ignition as well.

Did not get around to sorting this eve, but have my testing plan worked out.

I'm sure that your fault is different,but mine is with APM at present, with ECU being checked out by MBE. Hope its repairable or big bucks! I lost all power to fuel pump and ignition,though starter worked ,so immobiliser looks favourite on yours. Pump relay is in boot fuse board,brown colour.

I would not say I have fixed it, but it is working.

Suspect:

Wiring from inertia switch through to Pump Earth, sticky/failing pump -(I did almost run out of fuel a few weeks ago).

Intermittent/stuck relay on fuel pump circuit.

Dodgy Inertia Switch

The connections at the relay did what they are supposed to do while the pump was not going so relief that it is not ECU or immobiliser.

I shorted the fuel pump on and it burst into life. Plugged everything back in and off I went.

Going to replace the relay and clean up wiring to pump. If it happens again I know how to get home and can fault find further.

Thanks, Matt
