No start need help!!!
 
I have a 92 jdm fd. It is basically all factory. I bought it as a no start and it sat for 2 years. I had it running after using ether and lots of rolling it over and deflooding. It was running off one rotor in and out. The car had brand new plugs. I managed to drive the car a short distance but it started bogging badly then died and wouldn't even fire up for a second since. I have since taken the intake off and removed the vacuum mess and replaced all vac. Hoses left with new hoses and zip tied all ends. I verified I have spark. I have fuel. However not sure how much pressure yet, but my plugs were getting wet. I have tried the ATF trick I case it was carbon'd badly. I do know the previous owner parked it due to it running rough but he was an idiot and didn't know anything about cars in general. I checked the secondary injectors today for power and I have 12v on both sides of the plug with ignition on? I also went over the wiring and repaired the CAS plugs as they were crap and the wires were showing bare wires on both plugs. My question is. Where do I go from here? It rolls over nice but will not fire still. I am at a loss right now what to test other than fuel pressure now..I really hope for some responses here guys thank you

I would first do a compression test .Sounds like no or low compression on 1 cylinder

Ya I am going to borrow the compression tester for the rx8's from work. So it's looking like I need a rebuild or new engine from this point right?

Also does anyone know the resistance of the factory injectors? I'm getting 13.8 ohms on each injector. Primary and secondary. I have searched a ton and can't find anything
