never-ending lean condition: fuel pressure low? bad pump? voodoo curse? CAR IS WORSE!
in the million-year effort to diagnose why my car is still running lean, i've been doing some more poking around...
i think my fuel pump itself is going out (walbro 190). i did a bunch of reading on tuners and the only thing i hadn't checked for was crimped fuel lines. i cycled my pump last night and checked everything from head to toe, and there's def no leaks anywhere and all the hardlines look immaculate, besides for being insanely dirty.
however, while the pump was running i squeezed the fat rubber line that comes down from the top of the tank and could feel the fuel PULSING. shouldn't it be one continuous stream of pressure? it was like i was squeezing my dick after sex, i could feel it throbbing like a heartbeat, instead of just staying pressurized continuously.
spark plugs are still whiter than my ass and the motor gets hotter than hell after 10m of idling.
getting my AFPR w/gauge back today. gonna hook it up and see what my pressure is at. any other thoughts?
btw i checked the voltage at the fuel pump and its ~14.1v, rewire still holding strong. there's only about 80K miles on the pump, could it be bad already?
