    Check the engine compression. If it is OK check the fuel pressure.

    the fuel regulator is built into the fuel rail. im sure you have one. its one of the metal things in the center under the plastic cover. your problem is most likely an air leak. check the hard black plastic hoses for cracks especially coming out of the air pump on the bottom starboard rear of the engine. If that looks good, pull the spark plugs and crank the engine to make sure there is a nice even puff of gas coming out of each cylinder because sometimes the lower injector gets stuck open. lastly it could be a bad gasket on the air pump itself but that isn't as common as the other 2.

    you want to find a competent tech with the tools and know how to deal with any 951 engine. guessing is going to get realllly expensive really fast.

    You do not want to be making guesses.

    I'd suggest that you obtain the Candoo code reader system( available at the GH store) before it's too late. If you are getting a maint warning light, you absolutely need it, if there is no maint lamp, then you need to obtain a correct fuel pressure gauge and a good quality voltmeter for that side of troubleshooting. One thing the candoo can help you with is finding a bad air or fuel injector. You'll want to have a look at the high pressure air line on the motor to make sure it hasn't failed. That could explain the raw fuel smell since the unatomized fuel will not burn well ( if at all) and come out the back end.

    I'd suggest you read as many posts here on the DI as possible.

    oh yeah..welcome to GH.
