what I use is what I call 'substitute and bypass' strategy.

if the fuel pump won't run ..I just hot wire it.
if that gets me a running engine ...then I know all I have to do is work
on the fuel pump wiring circuit.

if you got the FP running by jumpering the relay ...
but it still won't run ..
some possibilities..
no igntion ..
or if there is spark out of the coil wire, but won't run, it's flooeded.
wrong ignition timing.
injectors not squirting,
no injector pulse from ecu to injectors
clogged cat or muffler
not enough fuel in the tank,
blocked or clogged fuel filter,
a pump that runs but doesn't really pump.
( what is the fuel pressure ? )

is the distributor in correctly ?
one guy managed to get his in backwards so it was 180 out.

firing order ?

The ECU turns on the FP relay for a second or two when the key is turned on but after that it only runs the FP relay if it thinks the engine is turning.
