25d manifold sti injector issue
Posted: Tue Jul 28, 2020 5:43 am
i feel like a dummy. I keep flooding the engine with the injectors. I bought new orings and it feels like they all seal fine inside the fuel rails. Now, all of my injectors are missing the center rubber pieces in the caps, ontop that cover the pin sticking upwards. As i prime my fuel system i can hear a very loud hissing noise and i end up filling all 4 cylinders with fuel. All 4 fuel injectors are unplugged. By keeping the spark plugs removed i turn the motor over by hand to push the fuel back out.
By not having those center caps ontop...is that causing my injectors to open and force fuel into my intake and cylinders? Ive tried 2 sets of injectors and both sets are missing the center caps ontop. Both sets also have all new orings. If its not the center caps then im starting to lean towards the fuel rail to manifold seals are bad? Though i thought if those were bad it would leak externally onto the engine, not internally. Ive been battling this for a few weeks and havent figured it out.
22e/25d hybrid. Removed the red top injectors in favor of the 550cc yellow top sti injectors. Having one hell of a hard time figuring out why so much fuel is being forced into the cylinders.
