That is trim pot, it controls air fuel mixture. You should not mess with it unless you know about it. But since you already have been playing with it so best option is to find mechanic who has a gas analzyer and ask him to set it appropriately,

i am also facing this fuel average issue but car starts on half crank. i have also saw this fuel misture regulator in dashboard but pakwheels users don't know about this i think. @Xulfiqar is expert he might know.

Please help op. This is happening after car sitting overnight and cranking for first time. He got replaced ect and you can see no cel is present. Injectors are also checked using launch machine.
What should he check to resolve the issue?

That variable thing is Trimpot and its called IMA in Honda. Its default voltage is 2.5V which can be checked by scantool connected and adjusting that trimpot. Secondly your car starting issue can be related to fuel pump or fuel filter problem, have those checked as well.

[babarhyd]

Ideal Fuel Pressure for Civic 7th gen is 42psi and not 52psi. Check your fuel pressure regulator which is in tank with fuel pump.

[hamxahamid]

Ok but thats not the reason bro. Even tried changing fuel pump

[Xulfiqar]

What is the fuel pressure at cold start?

And by the video it seems its screwing up the timing signal on startup. Has your mechanic checked the crank and cam signal waveform co relation on start?

[hamxahamid]

Yes he washed all the sensors grip.. And tuned tappet valves.. Check injector's spark coils plugs everything

[hamxahamid]

There was not even a single code in ecu (he scanned it 3 time in different days)

[hamxahamid]

Sorrry sir i dont know caz jab cold start honi ho tab gari ghar pay hoti hy to wo me khud to check. Ni kr paya

[hamxahamid]

ajeeb bat ye hay k phr aik bar start k bad theek q ho jati hay baki sara din half self start.. Or even aga mr rat me late night drive kr k aya hu to suba frak par jata hay k agr phly 5 self pay honi the start to 3 pay ho jaygi

[Hassan1991]

Let the pump prime first then try to start.
Fuel pressure inside the rail is dropping.

[Hassan1991]

Because after first start fuel pressure inside the rail stays there.
And When you let the car sit for night pressure drops.
