S40 won't start after sitting 7 months.
The car cranks and the engine turns but won't start, hardly even sputters. I checked that one of the spark plugs fires with a jumper cable and i did see spark. The Fuel pressure sensor was replaced and i was able to get a reading of 50-55 psi when a fuel pressure gauge was attached to the fuel rail.
I probably should have drained the gas but i didn't. It shows about half a tank
I noticed some rat poop under the hood.
Any thoughts on what you guys would try next? Thanks for your time.

I do get compression. Im getting plenty of pressure to the fuel rail. Could it be clogged fuel injectors not opening?

I (removed and) energized each injector while forcing pressurized carb cleaner through them and they didn't seem very dirty. I assembled the fuel rail and saw them work removed from the intake as they should. I reassembled and still no go. I drained the fuel tank using the fuel pump (i removed the starter fuse and held the key in the 3 position) porting out to a paint bucket and added fresh 2 gallons of fresh gas. The old gas didn't seem too bad.

Did you check the fuses? I haven't checked the wiring diagrams to confirm but on other cars the injectors are normally powered and the ECM provides the ground to make them fire. No power = no fire.
Everything else being fine then I think a wiring issue as in the mice chewed up the wires. I've seen it on cars that are stored for long periods.
