operator_13 answered about a year ago I'm gonna say there's a problem with the system ground....undo the lug that connects to the chassis ground and wirebrush that lug...and the space where it bolts to, think that insufficient ground to the relay box has the relays dropping out....combined with a battery that may be older than five years old has led to a relay dropping out....the fuel pump or ignition relay is not seeing sufficient voltage to stay engaged....test at the relay box for GROUND...and varying voltages from the corrosion that is holding up the show~

if i remember right there is a solenoid valve on them when starting it has to be down for engine to start. if it fails it dont get the pressure needed to start. when engine is running and warmed up it opens. cannot remember were it is but I used to have one a long long time ago. and it was this fault.

Are you able to crank it?Also check the engine block heater for functionality. It won't start else. Also I am assuming all fuel lines are primed? try cracking the fuel line to each injector as you crank it, and make sure the fuel delivery pump is working, This will also bleed the air from the system.
