New battery in voltmeter...now reads 12 something off battery...4 volts less...should equal about 14 at lift pump connection with engine running and with 4 volt error off voltmeter. Going ahead with the lift pump replacement. Thanks. I really like this truck, just got to work the bugs out!
Lift pump in, opened t-valve a little, fired right up, closed t-valve, fired up again....running great! Can hear the pump a few seconds after shutdown, just like before. I'm a happy guy again. Thanks for all the input I've swiped off this site! Spent around $400 on the truck with the remote PMD and LP, believe it'll be worth it.
