2017 Pioneer 1000 Hard start issues

[hunt18]

My 2017 Pioneer 1000-5 currently has about 1700 miles and is having starting issues(may take up to 30 secs to crank) only when the motor is cold. The issue has progressively gotten worse over the past couple months. It also has issues taking throttle if you mash the pedal hard. So far I have installed a new air filter, new spark plugs, cleaned spark arrestor, new batteries, new idle air control valve, valves have been adjusted and new fuel pump installed. I am at a total loss. If you spray just a little either in the throttle body when cranking cold it will fire the first time. All help/advice is appreciated.

Yes, I just poked you in the ribs and said
"Hey, we like to know who we are helping." 🤪
.
After everything you said you have done, an off the wall question, but did you try any injector cleaner? Seems like about the only thing you haven't changed.

Here is better help then me.
The search bar above works VERY well.
IF you can guess the right wording to search for. haha
I searched for "1000 cold start" and found many threads that might help you.

For cold start the intake air temp and coolant temp sensors should read the same cold. Your dealer can check them in a couple of minutes with the Honda tester. After warm up in a few minutes the intake air won't change much but the coolant sensor will change a lot. I was testing cars and at around 70 degrees they both would read around 3 volts. After warmup the coolant sensor would drop to less then 1 volt. If the coolant temp sensor is off by around 1/2 a volt it may not be rich enough to start. If you disconnect the coolant temp sensor the computer will keep enriching the mixture until it starts them go to a warmed up reading.
