Hello all, new here but have a 97 B2300 since last year.
I'm having an issue with the EVAP system and am curious about the function of the solenoid.
I have 12v at the solenoid connector with the key on and 0v with key off. I got a couple of spare solenoids at the yard along with another solenoid pigtail connector. With battery power across the spare pigtail connector, all of the solenoids energize.
Thinking that my original connector may not be making a good connection, I cut it off and wired my known good spare into place. Turned on the key, none of the solenoids would actuate.
My question is: Is the solenoid supposed to be energized (open) the whole time the key is on, or does the PCM/ECM open and close the solenoid during the course of driving the truck?
If it's supposed to be energized the whole time, then the current is low at the connector which would be a PCM issue, correct?
Thanks for any help!
