Hi there:
You wll have to pinpoint what the engine is missing...
- Spark
- Fuel
- Compression

All\012 three of these are tested when the engine is being cranked over. There \012are two way of checking for fuel. Fuel pressure and fuel trigger. Both \012are very important and must be present for the engine to start. Fuel \012pressure is self explanatory. You just hook up the gage and see what the\012 reading is. Fuel trigger is check with a noid light. The injector gets \012unplugged and the noid light gets plugged in to the injector clip. With \012the engine cranking over, this light must blink. This is the signal to \012the injectors from the computer. You can have all the fuel pressure in \012the world, but it wont matter if the injector is not pulsing gas into \012the cylinder like it should.

Compression tester, spark tester, \012fuel pressure gage and noid light are all accessible at your local auto \012store. All three tests play a very important part in diagnosing a no \012start condition. Be extremely careful when doing these tests.

Hope this helps; also keep in mind that your feedback \012is important and \012I`ll appreciate your time and consideration if you leave some \012testimonial comment about this answer.

Thank you for using FixYa, have a nice day.
