No voltage on CAPS pin 3 or TOPS (MPEM not supplying power)
Throwing a P0344 after rebuilding engine. Motor runs good and all seems to be fine except a P0344 code when running. Upon diagnosing, I am getting 0 volts on the meter at pin 3 of the CAPS whereas I understand I should be getting 12v. Also, testing for voltage (12v) coming from pin 2-19 on MPEM is showing no voltage as well. I notice the TOPS and the CAPS get power from the same wire (PU/GY)

Check your 5a fuse #8, Also you said your Tops valve is also not clicking.

Problem solved. The #1 (10a) fuse was blown in an unidentifiable area. Replaced it and now the code is gone.
Beertdart is a lifesaver. Thanks for the tech help.
