my r33 is hard to start for the first time of the day no matter wot time. i have to keep my foot down the accelerator to start it. once i get it warmed up, its fine. can anyone plz help me with this problem?

that would be much appriciated

also i tried reseting the ecu and it just made things worse, before it would start up run for a few seconds and stall if i didn't press the accelerator in but not it will not start unless i toggle witht he accelerator for like 5 secodns while trying to start

its a real pain in the ass, i'd heard of many suggestions but i need to know from someone who has had this problem

so far some of the reasons could be.

*fuel pump

*fuel relay

*injectors

*fuel pressure regulator

*ecu

*cold start valve

Make sure there's no fuse missing or blown in the driver's side fuse box under the dash. If the fuse labeled "starter signal" (in Japanese) is missing or blown, the car will be hard to start when cold. Do a search for the jap-english translation of the fuse box.

Also, check the coolant temperature sensor.

Just a few thoughts.

    • Based off what you’ve said here, I think I’ve figured out a good bit of what I’ve done wrong -  So on the line going from the PCV valve to carbon canister, there’s a T joint that is pretty much right next to that lower port - I hadn’t noticed that the hose in the diagram was curved to attach onto the carb, so I was putting that line for the lower port onto the PCV line / carbon canister line instead. I’m going to have a flick through the manual again tomorrow and should hopefully find a diagram that’ll show me where that T joint should be connected to. Timing also 100% needs to be sorted out as well, should be able to tackle that tomorrow as well. Definitely feel like I should be on the right track now though. 
    • The screw is for idle (pilot circuit) mixture adjustment. Else, I'm confused ~ the diagram shows 2 carby ports, and the intake manifold port, but you're suggesting the "2nd port on the back of the carb that isn’t mentioned in the diagrams" ...yet, both carby ports are shown...que?... ...in any event, that port should be connected, but if not (like it is now), it's unlikely to cause a backfire out the carby (it would introduce false air and give you a fast/lean idle) ...sounds more like timing issues/spark plug wire routing responsible for the backfiring.    
    • That's fair, I can see both points. I get enthusiastic when I see the FS section has a new post and want to see what interesting thing someone is selling. Then I get deflated it's a bump of a 10 year old post. Ha ha
    • Couple of litres of moonshine from his southern cousins would do it...
