Have a '96 Georgie Boy Cruise Master on a Chevy 454 P30 chassis. DH thinks we are having a problem with the fuel pump. I did a search but most of the topics are not specific enough for him! Anyway if...
When my fuel pump stopped working in the tank. It would start fine and run fine on the flat. Once it started to go up a hill or you needed to pass it would stumble and backfire. I don't think it's a fuel pump problem if all it is, is a hard start problem. Check the fuel pressure at the TBI. That will dictate if you need to do some fuel issue.
