Hi, has anyone here destroyed the immobiliser module on the injection pump to replace a faulty fuel cut solenoid? Any tips greatly appreciated. I don't want to remove the injection pump to replace the solenoid. Vehicle is a live axle 100 series with a 1HZ motor.

Regards

Peter

If you have a workshop manual (may be able to find on net)there is a diagram of a tool you can make to drill out the one way screws and remove the immobiliser.you can then fit normal screws with heads to undo in future.
Be aware that your insurance company may refuse a claim if your vehicle is stolen because the imobiliser was by passed.

Yeah, But I think that requires the removal of the pump , no room to get a drill in there while in the vehicle.

Mate, how positive are you that it is the fuel cut off solenoid ? I went a fair way down the same path last year - and yes, you have to take the pump off to drill out the snap off bolts & it will be expensive ~ $1500 or so.

The problem with my 100 turned out to be a flat battery in the nongenuine key- a new battery fixed it ! Factory key has no battery, aftermarket keys have one.

Whether or not that is your problem you have to make sure you have eliminate all other possibilities before doing the job on the solenoid.

The solenoids seem to be generally reliable and are rarely replaced,
i understand.

Cheers

Thanks Neil, definately the solenoid. It is not activating when power is supplied to it via a jumper lead from the battery. Solenoid can be replaced without removing the pump but it is difficult.

Check the wiring to the solenoid VERY carefully. I had an intermittent starting problem on my 105 wagon and it was dodgy wire between the plug and solenoid. Wriggling the wire didn't reproduce the fault all the time. Took a while to pin it down.

Thanks Brian, a bit hard to test any further really without exposing the solenoid, but I will try the jumper again directly to the solenoid before I replace it.

Peter,

I had that happen on Darkie on our trip to Lightning Ridge.

Ened up have the Fuel Pump removed and retrofitted with the non immobilizer fuel cut off solenoid of the previous (2002) model.

Cost was $645 including Labour from memory in Moree

Mr Toyota qouted the job at $2k ++++ for the immobilizer solenoid on the rear of the pump as well as the module under the dash to be replaced (need to be a matching pair) as well as a 2 week wait for the parts to arrive from Japan.

Read my Lightning Ridge Blog for a few more details if needed

Cheers Kev
