Check the connectors (J4 on mpu and J3 on Solenoid driver board) a bad ground can cause the solenoids not to fire and the ground loops back in J3 and it is common to have bad pins in that connector.

Quoted from Xenon75:Check the connectors (J4 on mpu and J3 on Solenoid driver board) a bad ground can cause the solenoids not to fire and the ground loops back in J3 and it is common to have bad pins in that connector.
Also have seen the Altek SDB not give out enough 5v to boot the mpu as a result of a bad J3 connector.
