All prestige remote start unit shall have a red switch for temporarily disable the remote starting function. Double check and see you didn't move the switch to off position. If it is in the on position and your parking light keep flashing, it means the tach wire didn't connect or you got the wrong tach. Also, prestige remote starter need "double press" the start button in order to work. Good Luck.

did you program the tach?
