Fuel/Power problem

[S3t0_S13]

check engine light is on for Fuel Injector leakcar will run about 80% of the time with full poweronce in a while the CEL will blink as if a sensor is loose or something and power will drop.. during this time car is running rich and small blips/backfires can be heard.

new plugsnew wiresnew fuel filter2 new injectors

many say the code is too general and could be ur fuel pump or pressure regulator acting uphow do i go about finding which is really the problem?

check your fuel pressure wit a pressure gauge it should read more then 32 psi. anything less means your fuel system is in stress and check your coil for proper spark use a ohm meter to check it and wires

so its blinking off then back on when its running bad, but otherwise on, right? id fix that problem before i tried to troubleshoot other issues.

yeai just dont necessarily know how to diagnose the problemi can go a week without seeing itthen sometimes it blinks without any pattern and im still at full powerthen it randomly cuts off for like a day or 2 with those symptoms

check your fuel pressure wit a pressure gauge check your coil for proper spark use a ohm meter to check it and wires
