Found the problem with the help of a kind Rv’ing neighbor. There were two issues. First was when the dealer fix the water pump the forgot to open up one of the valves. My neighbor with his longer arm was able to reach it and turn it on. Started getting water but at very low pressure. Discovered the check valve where the hose goes into the RV was damaged. Removed it, now getting pressure. Now off to find a replacement part for the check valve.
Thanks for everyone’s input.
