Starting

You need four things to get combustion in the engine - proper timing, air, spark, and fuel. First, check for an engine error code. If there is none, check for spark by pulling out a spark plug wire and place the lead near a ground. If you have a spark while the engine turns over, then that's one component down. If you don't, check the coil for a spark. If you don't get it there, replace the coil. Similarly, check the fuel filter and air filter. If nothing's turning up, then look at the timing belt.

Possibly the timing belt.
