Motor has not run in 10 years, conpression 110-115 psi. The wireing harness is missing. Is there a place on line were I can get a wiring diagram? I would like to try and star http://www.marineengine.com/discus/messages/12482/296143.shtml?1257647690#POST254073 Hopefully your problem has gone away. If not there are a few other things to check. 1. A clogged vst vent filter. It is the vertically positioned filter that is just above the vst. 2. A faulty fuel pressure regulator 3. A clogged PCV valve.
