azsr20det

So I bought my 240 (91 s13 with sr20det redtop) in 2010 it ran fine but was beat to shit. So spent up to early 2012 restoring it, then got busy with life and low funds so the car ended up sitting for 6 years in a storage unit untouched. Moved into a new house and towed it home. So back at the beginning of feb i decided to bring it back to life. Redid all the brakes and fluids and a bunch of other cosmetic stuff and then did the following to try and get it to start

-drained all the old gas out, refilled the tank with premium and a can of fuel system cleaner
-replaced the spark plugs and sprayed fogging oil into the cylinders
-drained the old oil, installed an oil cooler, relocated the filterand put an oil temp and pressure sensor/gauges in.
-refilled with extra oil (to fill the lines and cooler)
-checked fuses and relays all seem good
-got a brand new battery

Think i did some other stuff engine start wise but cant remember

Tried to start car, cranks good but wont start. Read thats either because of no spark or no fuel. spark plugs are new, coils and wiring there is all fine. Worked before and didnt mess with any of it. I have an inline fuel pressure gauge, its at 0psi so i thought, must be the fuel pump. Prior owner put in a walboro 255, so today I put in a brand new walboro 255 fuel pump. Still cranks but no start. Still 0 psi. I have NO IDEA at this point whats wrong. Any advice would be greatly appreciated ive put so much into this car and just want it to start again
