Go to Post I've been inspired for real engineering during the build season and on the playing field, but the inspiration I found in the pits is often for creative thinking and intuition. - artdutra04 [more]

Re: HELP NEEDED: Solenoids not firing

I've had solenoids that were directional.
The LED generally turns on, but the coil does not trip when wired backwards.

If they are pulsing too quickly, then that will show up on the PCM indicator per solenoid.
For a double solenoid, if the PCM light is on then the solenoid will be driven to the corresponding position. If the light is off, then the position is indeterminate. If both sides of the solenoid are tripped at the same time then it's also not going to move.

For a single solenoid, the PCM light has to be on for the solenoid to move away from the home position. When the PCM light is off a single solenoid will return to the home position.
