If you engine has no big mechanical failure, it either has no good ignition or no fuel.

1 Ignition.
The best way to check the ignition is with a stroboscope lamp (oscilloscope is even better, but very expensive).

The second way is;
- find about 5 feet of metal wire
- take all plug out
- Put the caps back on
- fix one end of the wire to the engine
- wrap the wire around the metal part of the plugs (upside down)
- Make a string of all six plugs with the wire and fix the other end
to the other side of the engine.
- Pull the fuel relay
- Have someone crank the engine and watch the sparks. They
should all fire (powerful spark)

Do not stand to close to the engine, some fuel/air mixture may come out and ignite!!

Put the plugs back in and reinsert the fuel relay.

2 Fuel delivery.
- Take two open end wrenches and loosen the fuel lines from the
injector (just a little bit loose).
- Have someone crank the engine and see if fuel seeps out of the
lines.
