MMM problem

[traxxasrevony]

just got it swtched back into my only working truck lastnight and gave it a quick test with no pinion on the motor and everything worked fine. then i unhooked the esc from my y harness to mix the esc and brake servo so i could program it on the comp. today hooked it all back up and nothing. it will calibrate,arm, and link to the comp. it gives tones thru the motor but thats it. when i give it throttle the green light on the esc flashes and thats it same for brake.

anybody know what could be wrong here.
