you did the right thing Craig. you will NEVER learn how to fix this crap if you don't get in there and do it yourself. now you know something you didn't last weekend, and learned a lot about your car in the process. in my opinion, that's the only way to do it. buy the special tools if you need them, and get in there and figure it out. I've worked on cars since I could walk. Last year, I bought a project truck with a 8.2L Detroit Diesel engine. not running. it would crank, but not start. engine seemed fine, had to be something not major. I HAD NO FREAKING IDEA OF HOW A DIESEL EVEN WORKS. I bought a manual, and dug in! found all the injectors to be stuck. These are not normal injectors, they are mechanical injectors, pushrod driven off the cam. when you pull the valve cover, it looks like there are 3 valves per cyl, but one is the injector. So i pulled them all apart, cleaned the million little tiny pieces that make up the injector, put them all back in, and a few days later, she fired right up. I went from knowing nothing about diesel engines, to doing a repair that when I called around, would have cost me well over $3000.00. Yup, 3 grand, diesels are very expensive to have worked on. Interesting Diesel facts:
diesel engines run on air, not fuel. the fuel acts like a spark plug to ignite the compressed air
because there are no throttle plates, diesels do not produce any vaccuum
many diesels do not need an intake manifold to run. you can take the intake manifold off, and it will run just fine, it just won't have filtered air
because they run off air, not fuel, you must be very careful around a diesel so make sure it doesn't get a "wiff" of something flammable. a propane leak next to your BBQ will caust a diesel to "run away" as it will rev until it explodes. Turning the key off will have no effect. same with WD-40, don't spray it around a diesel while it's running.
the only electical component a typical diesel needs to run is a starter. if you could crank the engine with no starter, the engine wouldn't require an electrical system.
you can dump cooking oil, motor oil, vegetable oil, right into the tank of any diesel, and with no modifications, it will run just as well as it would with pump diesel fuel.
