You will have to pinpoint what the engine is missing...
- Spark
- Fuel
- Compression
All
three of these are tested when the engine is being cranked over. There
are two way of checking for fuel. Fuel pressure and fuel trigger. Both
are very important and must be present for the engine to start. Fuel
pressure is self explanatory. You just hook up the gage and see what the
reading is. Fuel trigger is check with a noid light. The injector gets
unplugged and the noid light gets plugged in to the injector clip. With
the engine cranking over, this light must blink. This is the signal to
the injectors from the computer. You can have all the fuel pressure in
the world, but it wont matter if the injector is not pulsing gas into
the cylinder like it should.
Compression tester, spark tester,
fuel pressure gage and noid light are all accessible at your local auto
store. All three tests play a very important part in diagnosing a no
start condition. Be extremely careful when doing these tests.
