First off im brand new and i have done a ton of searching but i cant find anything that helps my situation. The car started for about 5 secs but hasnt started since.

-New swap into a zenki
-Has spark and fuel
-I havent checked timing but sr was pulled out of running s13 in japan and shipped here
- brand new wiring specialties upper snd lower harness. So wiring is good

Any help/insight would be awesome!!

My bet is on your timing, check it, it's pretty simple to adjust if it's off a tooth when you get the hang of it.
Also after each attempted start you do, pull the fuel pump fuse and give the car a crank to burn of excess fuel. Not doing so can lead to too much fuel in the cylinders, which can cause a hydrolock

try resetting the ecu? unplug battery press brake pedal in 10 times(come completely off pedal) replug battery and try. also when i first did my sr it wouldn't start unless i held the gas the whole time, sorted out issues later.

I will try the reset. Will the reset erase my tune? I got a enthalpy tune.

Also hold gas and clutch to the floor?

Disconnect the fuel hose attached to the fuel filter and put it in a jug. Make sure fuel fuel comes out when the pump primes.

One of the most common causes of this issue on a fresh swap is to get the fuel lines backwards.

If it is just cranking, begin by making sure you have good fuel pressure at the rail.

You say it has fuel and spark, how did you check that? Next options would be electrical. Go through each plug on the harness and make sure it is plugged in completely. If the timing was off just a little, it would still startup, so timing is not the issue from what it sounds like.

Definitely check fuel lines are hooked up right, thats a good place to start.
