MY SETUP:
'96 SE S14
S13 SR20DET BLKTP
1.2 MTL HG
COMPRESSION: approx. 165/163/160/160
S13 SOHC MAF
S14 turbo @ 7 lbs
WALBRO 255 w/ NISMO ADJ. FPR

Has 3.7 liters of OIL
3/8 tank of GAS
50/50 MIX of COOLANT

I drove the car already for 1,000+ MILES with NO sign of a problem, till I installed side skirts, and when I made the Oil+Filter change. My motor does not start, and this is what has already been looked @:

Timing is set to 15 degrees below TDC
Spark at all 4 coilpacks
Light on ecu lights up when KEYED ON
Swapped ECU with a known working ECU= SAME SITUATION
Fuel pressure at approx. 60 psi
Each of the 2 wires (http://www.zilvia.net/f/showthread.php?t=158149&highlight=50%2F50+coolant#) on all 4 injector connectors have NO PWR when KEYED ON
Battery + Oil pressure (http://www.zilvia.net/f/showthread.php?t=158149&highlight=50%2F50+coolant#) lamp light up on gauge cluster which NEVER lit up in the past.
No blown fuses in both fuse boxes, except for wipers-which i dont have because the wiper plug was chopped off by the previous owner... if at all relevant..
Swapped out BLUE relays (@ the moment dnt knw function of BROWN relays)
Engine harness has no cut or ripped wires!If you have any idea what the problem could be, PLEASE dont hesitate to help a ZILVIAN in distress. I dont have very many days left for sick leave..

THANK YOU FOR READING!

Umm...check a 240sx manual if you can to see which relay your fuel pump is...it might be a bad wire or the pump itself went bad/faulty.

Can you hear it turn on when you turn the accessory? Follow the wires from the injectors and see if they have been skinned somewhre and shorted.

btw there are 3 fuse boxes...the 2 under the hood and 1 under steering colum if you wanted to check those to make sure? GL and test some of those thought and see what happens.
