this weekend took out a friends advantage with twin 500 efi engines .they both started right up and ran great all day shut them off and then left one wouldn't restart limped back to dock with just the right one running. changed water seperators and fuel filters on both engines both started up and ran to the first no wake zone the left one died again at idle checked spark and it had it couldn't find a shrader port to check fuel pressure so squirted some gas down intake still no fire bought a ignition module and coil and then it fired right up . while fixing left engine shut down right one and now it won't refire tried the module and coil on it also but no luck . is there any way to check fuel pressure ? any other sugestions on what to look for ? thanks
