    Yeah, change the injectors. If they are dribbling into the manifold it will cause exactly what you're showing. In fact, I'm pretty sure that's why I ultimately replaced mine. It was flooding out on warm restarts. By morning all the gas has evaporated (or run down into the crankcase, doh), so you have a clean first start.

    The main relay almost a maintenance item at this point. Replace it just to be sure. Resoldering is a jury rig at best and won't work if the relays inside it are failing. It's a $50 part + 1 hour of profuse swearing under the dash, then you're done for another 50k miles or so.

    Okay thanks. I just wasted even more money changing the injectors because it did not fix the issue, what confuses me and has me even more frustrated is how can the main relay be the issue when the temperature of the inside of the car remains the same (cold) but the engine is hot? I have read where the interior will get hot and then the car wont start for the main relay or am i just reading something wrong? I am sick and tired of dumping money into things that " might" do the trick when they have done literally nothing. I'm not mad at anyone but myself here lol just in case anyone took that to heart. I'm trying to get this thing out of its shitbox status and more of a car meet car, something that i don't have to unplug the fuel pump to get it to run when warm. I'm hoping to get some concrete answers on this, you guys have been around these chariots longer than I have and im hoping you could pass down some of that wisdom. thanks.

    To be fair, the parts you are replacing are 30 years old, it is not in vain

    These cars teach you to test and diagnose issues before replacing parts. Have you tried using resisters to rule out the TW sensor yet.

    The injectors you replaced were leaking pretty bad and needed replacing so I dont see it as a loss. Leaking fuel right near spark,heat etc never a good thing long term.

    I updated the TW sensor thread in the EFI section with copy of the Helms manual troubleshooting guide.

    Re: Warm restart issue

    Interesting development, unplugging the green which if im not mistaken is the TW sensor makes the car run like trash cold. I unplugged the white one just now that is next to it and it threw a code. Code 10 to be exact. which doesnt make sense because that is for an intake temperature sensor. I thought that was located elsewhere in the engine bay. ill post a video here in a second.

    Looking at some of the pictures over the years it seems the sensors positions are potentially swaped different years. Just to make it more confusing.

    Re: Warm restart issue

    OK very weird.

    Your intake temp sensor is on the intake manifold right near the brake master cylinder. There will be a mess of vacuum lines there too.

    The Honda ECU codes carry over for years with the TW sensor being 6. I cant really see it being a different make or model problem.

    EDIT: Did you ohm it out the TW sensor and see what you get cold and fully warmed up?

    I would always pay attention to what the book calls out for the WIRE color first, then the plug color, and then the color of the sensor.

    They way the sensor works as the car gets hotter i forces the car to run richer. So like in my case once my car was over heating my air fuel ratio was 9 to1. helps protect the motor in a ham fisted sorta way.

    Hope that helps in anyway.
