Don't know what your vehicle is but if it is fuel injected, it may have some fuel pressure but if it doesn't have the required amount of fuel pressure it isn't going to start. Do a fuel pressure test, you may have a bad fuel pump or bad fuel pressure regulator. Also check all the fuses. Also check the timing belt if it has one, it may have jumped or broke.
because its on fire
try replacing the spark plugs
Does it have fuel/ compression?
appears no fire going to spark plugs
Make sure connections are on tight.
injectors not pulsing, on the right side of the center consol or the left there is a relay it is gold in color check and replace
do you have fire at the plug? if not the cap has coil in it and needs replaced
A good place to start would be the Dist. cap, rotor,and coil.
You may have overheated the engine or seized it.
Is it getting fuel? Does it have compression?
sounds like the glow plugs need replacing
