My boss has a BMW in storage with no main battery installed.

It has a Thatcham Toad alarm fitted that seems to respond once we fit the car with a new battery.

Locks, unlocks etc' Only problem is, we are not getting a voltage to the fuel pump.

Could this still be an alarm immobiliser issue due to its onboard battery having gone flat?

Is there a way to simply disable the alarm completely? or do we have to wait for the alarms onboard battery to re charge?

Any help would be appreciated.

 

Thanks in advance.

Most likely the relay on the immobiliser has stuck...... What Toad model is it??

C4 T I think Russ, i am not sure to be honest.

If it is the relay, is there a quick fix?

Not a quick one as all wires are one colour.... Black..... and being an insurance approved system it should be buried deep behind the dash to stop tampering.....

What year is the BMW?

Have you checked the BMW fuse and relay to the fuel pump?

Also if it is a later model BMW, has it got built in OEM alarm and immobiliser?

If you send me the info I can speak to the BMW technicians at work for some advice on Monday?

Cheers Russ,

I think it is 1988, it's an M6 of some sort.

It was built to order. something like 48 of them made. Highline, or something like.

I will try and get some more details on Monday if that's ok

Appreciate your help mate.
