Does the engine turn over but not start?
If so, check for spark at the plug. (With a spark plug checker)
If no spark, check the coil/coils. (You'll have to purchase a service manual that details the specs.)
If you do have spark, move to fuel pressure next. (Fuel pressure gauge)
If no fuel pressure, check pump. If you do have fuel pressure, check that the injectors are firing.
If you have good spark and fuel pressure (with injector firing), then check the crankshaft/camshaft sensors and the MAP/MAF sensors.
If everything checks out, then you have a bumb computer.
