SR *Calling all SR/S14 wiring guru’s!

S13 sr20det In s14

It ran perfect 3 days ago. Changed the master cylinder, went to start it and boom won’t start. Cranks beautifully, just never starts. I feel like I know “alot” about these motors and the wiring. Maybe I’ve just forgotten??

I’ve:
-Got Spark on all coils
-Got Fuel coming out of all injectors (tested with rail off)
-Got proper voltage on Cas
-No glaring VAC leaks
-I took valve cover off and reset timing.
-Fuel pump is switched and I can flip on and hear prime
-I have power on the power pins on ECU

*Note* I drove the car weekly. Then it sat for a couple years. I trailered it to my new house out of state. Put some fresh gas in it and it fired up and ran smooth. Started it multiple times that day (few days ago) and it hasn’t ran since.

Any advice will be appreciated and noted. Thanks fellas.

It sounds dumb, but what about plugs? No mention of them. What about compression? Dry and wet readings?

Have a great day,
