Tossed fresh coolant, oil(and filter), power steering fluid, and a new battery in the car last night.  It cranked strong but would not fire.  Only got a chance to try a couple of things, so i'll horse around with it more tonight.  There's definitely fuel coming through the new filter (i loosened a fitting on the line to check).

Nope, didn't want to bore folks with the details.  Fred's helped me with some advice on a couple of things.  Still not running though.

I'm going to pull a spark plug or two and check the end for fuel.  It's possible that the Injectors are not firing for some...reason.  I know the injectors are actually getting fuel, because I pulled the fuel pressure regulator off the rails and it absolutely hosed me with a cool refreshing mist of '93.  Fuel pump and Fuel Filter(new) check out similarly.

Symptoms:
-Car cranks but does not even sputter.  I suspect the Injectors aren't firing, but why?  A bad ground somewhere?  Disconnected "mandatory" sensor or wire somewhere?

Things I tried:

Fuel:
-Fuel Pump Primes into bucket on prime
-Fuel Pump flows fuel into bucket on crank
-Fuel Filter flows fuel into bucket on prime and crank
-Fuel Pressure Regulator flows and doesn't barf fuel into the vacuum line
-Fuel rail is definitely pressurized, got a serious spray when I disconnected the regulator

Electrical:
-Tested all 4 ignition coil packs, all showed spark in plug, when held against block
-Replaced Battery Negative Terminal Connector
-New Battery
-Visually Checked all engine bay and passenger compartment fuses and relays
-Meter-tested all engine bay and passenger compartment fuses and relays
-Tried both the JDM and USDM Oil Pressure Switch
-Cleaned, wire brushed, and installed 8 or 9 electrical grounds on body
-Inspected most ground wires between neg terminal, engine, and body for play and broken wires within sheaths.

Timing:
-Tried both the JDM and USDM Crank Sensor
-Tried the JDM and USDM Cam Sensor
-Counted sensor-read teeth on back of crank pulley (same between engines)
-Counted sensor-read teeth on back of cam pulley (same between engines)
-New Timing belt service, everything's still lined up correctly.

CELs:
-Detected 1, P0183 Fuel Temp Circiut A high  --> The internet is out on whether this will stop the car from starting (on almost every subie-specific thread, the answer has been no)

What tells the injectors to fire?  Follow its path and test it ALL.  Use your software testing techniques.


Mine was no spark,  caused by bad connection in the power pin on the ECU plug  with the pin on the ECU side.  That was a massive shitshow to determine...
