My question is why??
Unless your doing exhibitions..I see no point in scorching your paint, possible fire and explosions..as well as injury up to homicide..(and they will charge you with it..if it happens!)
About the only way you are going to do it is with a Bottle fed gas into a Self excited spark generator into a spark plug..anything else is not going to work..you won't pump fuel without fire..the injectors will shut down without reference pulse from the dizzy..the cat won't allow it OR worse Collect it...(KA~BOOM)...
Plus you can get into serious trouble with the law depending on where you live..(possession of a destructive devise..a Felony and state pen time..like having a pipe bomb..)
But it's your call..
