I got mine second hand from ebay for about $50 but you have to wait ages for it to turn up. With the wrong ignitor module my car still started, it was just rev limited. Do you know what part number your ignitor is? should have a sticker ontop.
You might have a break in you distributor wiring or something. Before getting another ignitor take your distributor cap off and check there are no breaks in the wiring. Also check the main coil lead.

Also check if you are getting any spark with a spark plug out.

So is def fuel pump as the car will run with start ya bstrd in the intake (finally had a second person with me). Fuel pump pumps when the car starts but doesnt prime when the ignition is on and then cuts out once the starting sequence has finished. So (my best guess) either it's a relay/fuse somewhere or the ECU isn't telling it to switch on. 
 
On the 3S-GE is there a fuel pump relay/fuse hidden away somewhere? I've checked all the c/opn and efi relays/fuses but had no luck.
 
Cheers!

I'm not to sure how it all works in regards to how long the fuel pump should run on ignition (if at all). I just remember hearing some whirring/electronicy noises when the key is turned to ignition, and I'm getting non of that, just silence.
 
I took the fuel return off and no fuel came out when the key was on ignition (which might be normal, unsure) but fuel did piss out when i kicked it over, so at least the pump isn't dead.
 




I have a permanent fuel pressure gauge fitted to my stock '90 model NA mounted after the filter.
Things I have noticed about the pump running sequence:
With just the ignition on, the fuel pump will not work - no pressure.
But then if you crank the starter, (even if only for a moment) the pressure comes on instantly to about 40 psi and stays there whether you start the motor or not.
 
If the motor has been running, when you switch off, the fuel pressure then takes a couple of hours to drop to zero.
