Some questions were asked about powering the Fuel Pump, LH and EZK ecu. Here's an annotated diagram that helps a lot.
Ok, the sequence:

• Switched +12v from ignition switch goes to alarm unit if applicable.
• From ignition switch it activates the EZK relay
• The EZK relay powers the LH and EZK ecu
• If the EZK sees timing sensor pulses it activates the LH ecu which needs to supply fuel
• The LH ecu activates the LH relay which sends battery power to the IMR which in turn sends power to the 8 Injectors.
• The LH ecu also activates the fuel pump relay which sends battery power to the pumps.
