Someones said this aswell to try
if you're not getting sparks or the fuel pumps priming, Id check the wiring to make sure the ecu is working. can you hear the relays click when the ignition is turned on? if not make sure you have a live ignition feed from the plug by the coil. the black wire should be at +12v when the ignition is on. also when the ignition is switched on and the ecu is working, the wires to the injectors should be at about +10v (from memory), as its a negative pulse that fires the injectors.
if you can get a spark, then the ecu should be working. if you cant borrow a spare ecu I've heard of people using one from a GT to see if the ignition will work.
also on a GT the fuel pumps will still prime even if a distributor isnt connected
