Are you getting a check engine light? That is the first place to start (Have computer scanned)
All no start problems are diagnosed in the following order.
1. Spark (check plugs, wires, etc)
2. Fuel (Check relay, pump, filter, injectors, etc)
3. Compression (for broken valves, cam lobes, lifters, etc)
4. Computer/sensors (bad contacts, burned wires, failed sensors, faulty computer, etc)
Scanning the computer for codes should be first, but suspecting a bad computer or sensors should be saved for last.
