With all electronics... best practices are to verify voltage first then continue downstream. When you do your next valve job , I would disconnect battery , verify both connected and disconnected voltages, then check and reseat as many connectors as possible with voltage off. Connectors can be deceivingwhen plugging in ,may actually become misaligned and push a pin out of the connector housing. Rare but true and have seen it happen much to my bad luck in fixing stuff. Not saying this is the problem but you have to check those pesky electrics in a f.i. /vibration situation. Also some of those modules just start experiencing intermintant issues and just hav to be tossed out and replaced sometimes. (ie throttle position sensor etc.)
