What is the job of the ignition amp/module is it to send pulses to the fuel pump relay...?

Yes mate it sends a pulse to the coil and pump relay. A mate had same problem as and he replace the module and it sorted it.

Yes that make a lot of sense as me fuel pump aint running properly neither the rpm rev does not work either....

The is a wiring diagram I've drew up purely of the ignition system in question:

And with fuel pump added the wiring diagram:

Heres what another member told me:

The ignition amplifier takes a small low current input signal and switches a high current signal on the output to ground (hence amplifier).

Here it 'charges' the ignition coil primary by pulling it to ground, this typically lasts 2-6ms, the ignition amp then releases the now saturated primary. Now you see a large flyback voltage which is clamped by the ignition amplifier to 350-400v. This high voltage flyback voltage is stepped up by the ignition coil/transformer to several thousand volts on the output of the secondary.... where you get spark.

The ignition amp replaces the points and condenser in an old school distributor setup and is still used in modern cars either inside the ecu, as an ignition amplifier or right on the coil its self for coil on plug setups.

It does not do anything to do with the fuel pump of fuel system

So a bit conflicting results from different opinions...

Heres a Haynes manual quote:

The safety module ( FUEL PUMP RELAY) is located under the facia panel on the driver’s side and is coloured purple.
Its purpose is to shut off the power supply to the fuel pump should the engine stall or the vehicle be involved in an accident. The module senses
ignition pulses, and cuts the fuel supply if the ignition pulses stop.

So where does the fuel pump receive its ignitions pulses from....?

The ignition module/amplifier...?

Here is pic of new ignition amp and wiring numbers:

I Take it that
= 31 is earth
= 15 is switched live
= 1 coil

what are the other numbers???

Anyway did you get it sorted?
