My car wont start, it was throwing a 1222 (lamda sensor 1) code.
it’s not the idle control valve, it’s not the afm, (I swapped both of them out). it’s not the o2 sensor (I unplugged it and the car still didn’t run).
It’s not the fuel pump (it’s new) and it’s not the fuel filter (also new).
It won’t start. If I crank it, it starts after about 5 tries, but dies a second later.
When the fuel pump was out I started it for a brief second to make sure the fuel pump was working and it started right up no problem (I turned it off right away).
I don’t have a fuel pressure gauge. Anyone know where I could get one?
so what do you guys think it is? fuel pressure regulator maybe?
is there a fuel line nozzle like on a bike tire, press that with a pin or soemthing, if you get a huge spray your fuel pressure is fine. just dont spray your face
if theres a spot on ur fuel rail to mount a fuel pressure gauge then i can lend a hand. ill take mine off the civic and give ya a hand troubleshooting.
