Signs of Failing Fuel Pump / Injector?
What are the signs of this on a boosted vehicle?
Im experiencing:
1) AFR jumps to lean while cruising randomly
2) WOT got leaner
3) After turning car off it will not restart easily even after waiting 10 minutes....
(cranks for days)
4) Trouble starting cold SOMETIMES but not normally
5) When cranking with failure to start i do smell fuel
6) Sometimes car shuts off while idling
7) Sometimes i hear the Walbro whine when key is in "ON" other times i do not
Could this be a starter issue with 3/4/5?
I am running a Auto ECU & Harness and i have to keep unplugging the fic everytime i turn car off for battery drain issue (we rewired it with the DIY fix but did not work)
I just ordered a Manual engine harness and i have manual ECU so we are going to finish that swap but idk whats going on here.

Almost sounds like injectors aren't seated correctly. If you smell fuel, then you have a leak either at the fuel rail or at the pump. My 1st guess would be leak @ injectors. Try taking them out and re-seating them. If you have anything besides the stock fuel rail, make sure all plugs/connections are tight and have thread sealant on them. No sealant = fuel leak.
