Guys I’m stuck,
I am trying to help a buddy with his SR20.
Car runs great while running. When it’s hot, you shut it off and try to restart it and it just turns over and over and sometimes backfires. Once it cools down it starts no problem. Timing when hot is at 15 degrees before TDC.
Fuel pressure is at 43psi with vacuum. Replacing FPR to correct fuel pressure back to spec. New plugs have been installed and gapped to spec. New igniter for plugs. New coil packs. New coolant temp sensor. When cranking I can hear the injectors clicking (verified with stethoscope). Verified spark. I know usually if the CAS craps out it wouldn’t give me fuel or spark. But it’s honestly the next thing I’d want to try, just skeptical because these usually fail out right and not just when hot but I could be wrong. Any help would be greatly appreciated!
