Engine sat for two plus years without being started. Have completed the following.
-Replaced fuel filters.
-Replaced high pressure fuel pump & sleeve.
-Replaced low pressure fuel pump.
-Compression tested all cylinders
-Replaced spark plugs.
-Checked spark to all plugs.
-Fuel & air pressure both tested fine.
Motor will not start every time, when it does start & run it sounds fine. Sometimes it will shutdown by itself & then not start again. Sometimes it will start & sound fine then when I shut it down it won't start again.
I believe fuel is not the problem even though it sounds like it's running out of fuel when it shuts down. I think there may be an intermittent electrical fault that is causing the problem.
Any suggestions would be greatly appreciated.
