Have you tightened the injector lines? Mine won't start if they are too lose, you just need to crack, they will just dribble. You need to be very careful around those lines, 17,000 psi will cut off fingers and such. I've never loosened mine enough to get a spray, just a little dribble on the nut. sometimes that is too loose and it won't start till I tighten. good luck.
