Those pics make my eyes hurt.
I don't suppose you could delete them and add something from a more steady camera?
For cold start - - go to the junkyard and get a cold start injector from a Toyota, then add that to the bonnet. Get one that will spray in the right direction, there are several styles.
Wire it to a momentary push button on the dash and you are all set. You could also wire in a DPDT switch into the horn button circuit (horn switch in steering wheel grounds to activate) and you could do the same thing for the cold start injector.
Flip the switch, and when you start the car you just push the horn button a few times for fuel, and as it is warming up. It works great.
Then flip switch the other way for horn while driving.
