VR-4: No Spark + No Fuel = No Start

[T is for TURBO]

The starter cranks normally, but the engine won't start - At least you know that the starter is working. If the starter cranks but the engine won't start, there could be wide range of problems. Here are some of the most common:
- Problems with fuel delivery system (e.g bad fuel pump, fuel pump relay, clogged fuel screen, etc.)
- Problem with engine electronics (e.g crank sensor, cam sensor, air flow sensor, power relay, engine computer, etc.)
- Ignition system problems, especially on older vehicles with the distributor (e.g bad ignition coil, commutator, rotor, distributor cap, etc.)
- Defective ignition switch
- Problems with vehicle security system
- Internal engine problems (e.g broken timing belt or gear, low compression, etc.)
