Re: 2000 rav4 2.0 Diesel engine turns over but does not...
Run the fault codes first.
may be air in the fuel system
does the starter spin the engine fast ( slow cranking speed will not start a diesel)
are the glo-plugs working

Sometimes an air bubble - just before the injectors cause this problem. Loosen the fuel line there and crank the motor. Fuel pressure should force the air out and then fuel will squirk out. Turn key off and tighten up the line. Hope this is it. Other diesel fuel start tips are listed below that will help. http://www.auto-tune-up-and-repair-options.com/diesel-additives.html
sounds like cylinders are full of diesel you need to pull injectors to relieve pressure on cylinder.. it causes it to lock the engine up .. you might have left the key on with a leaking injector and filled the cylinder with diesel and then it would lock you engine.
You should need go empty on a diesel. You will need to bleed the system for it to start. Some do it on their own from simply cranking. You might try a couple of shots of starting fluid in the air intake. First remove the air filter. The speed of the engine turning runs a fuel pump that pushes the fuel to the injectors.
poss the fuel filter has petrol in it,replace filter,turn engine over with fuel line unattached to clear lines then fire up,should be fine.you may hve a hot start problem for awhile but fill up with diesel at 1/2 tank to dilute any petrol left.in 32 years in the trade i have put petrol in so many diesel cars,and as long as it starts,keep it running,and start only when cold ish.
glow plugs preheat the fuel to help the engine start.....when its hot outside its not that bad...the colder it gets the harder it will be to start with bad glowplugs..
If a diesel, you might check the diesel pump drive belt (at the right side of engine when looking at the engine from front of car). It's possible the teeth on the belt have stripped and put the pump timing out. An alternative may be a "stop solenoid" failure. The solenoid stops diesel getting to the injectors when the "ignition" is turned off and "stalls" the engine.
I don't know if the injector pump on a petrol engine has a similar setup as a diesel but it might be worth checking.
