These symptoms indicate an issue with fuel pressure. A faulty pump will not throw a pump specific code. Based on what you've already done to resolve the issues and a quick web search, you may have a faulty fuel pump. I must warn that a faulty fuel pump could leave you stranded at any time.

[@protipsplus]

There appears to be two fuel pumps on the 18'. One pump is located on top of the engine, and the other is mounted inside the fuel tank. The pump on top of the engine can go bad due to poor engine oil maintenance, dirty oil, and low oil pressure.

@@protipsplus where is the fuel pump located on top of the engine on the 18? if that one would fail would it cause a small knocking sound?
