Outer Limits 4x4 Board

hay everyone
i just got a GU witch is half converted to a TD42T ( the very later modal one factory intercooled) and it has 3 wires coming out if the pump and 2 wires going into a solenoid or senser in the bottom of the pump.
i have been told i need to put power to 2 of the wires to make it go. but i have no idea witch 2 wires. anyone dune it before or can help me out

That is the immobilizer model pump. I cant' remember which wire, it's one of the three. If there is a red one that rings a bell?? Sorry thats all I can recall.

thanks heeps mate that gives me some where to start

You will need to remove the immobilizer unit. It receives a signal from a main control unit to make it start. If you have all the modules and wiring then all should be ok if connected correctly.

i havn't got the computers and wiring for the immobilizer is there any way around it or have i got to change the pump or part of the pump

You will also need to power up the TCV (Timing Control Valve) at the bottom of the pump,normally a boost sensitive switch is the best way to switch it on and off.

The immobilser can be removed, however it is difficult to do as the use sheer bolts to locate it. Having a timing control valve throws a spanner in the works as it will make the pump have full advance at all times. It usually recieves a duty cycle controoled voltage to control the opening time which controls how much injection advance you have. This can be changed to a mechanical system but involves changing the main housing.

its pulse width modulated, a on off switch isnt going to do much here.

put a hoob switch in the cooler to turn on and off using boost pressure, it makes a big difference when driving..... but with out using it , it will still start... we modify these on late model gu's...

On and off with a Hobbs switch set to 3Psi is fine

ok thanks heaps everyone that has been a big help

I got one going that had failed in the immobilizer just with a voltage at one of those three wires, possible because the unit was faulty. It's worth a try.

i drilled the illommobiliser off yesterday and exposesed the fuel cut solenoid. to ezy somthing went right for a change
