Just got a call from the shop they test drove it and it works. It was an expensive lesson, the cost to diagnose and replace fuel pump was $ 1100 plus all the parts I changed trying to fix problem. The previous owner changed the pump before I bought it. If your MH fails to start with one crank and you need to give it gas to start it spray some starting fluid into tbi and see if it stays running. Thankful that it is now fixed and thankful to Bud for all his help he took us to Grand Coolee Dam and saw the lazer light show and Leavenworth which is a reconstruction of a Bavarian village while we waited for the MH to be fixed, stuff we would never have found on our own. So now on to Mt Rainer. Thanks again to all who posted ideas.
