A pulsejet motor can be started at ZERO ground speed when you supply
sufficient airstream. Once started pusejet will wor fine when you cut this
additional airstream. You can start ramjet in the same way, but when you
stop auxillary airstream ramjet will cease to work. When in high school I
attended two semesters of aeroengines. I recall one lesson when we started a
pulse jet in the way described by Keith. It took 15 min to ignite the motor
but then it worked fine. What a noise!!!

You are correct -- but some pulsejets don't even require forced air to
start. You can see a video of my self-starting pulsejet on my website
