### Diagnosis and Testing

#### NO START TEST

1. First, conduct a spark test as follows.
2. On the 2TZ-FZE engines, remove the exhaust pipe heat insulator.
3. Disconnect the coil wire from distributor. Hold the coil wire end about 1⁄2 inch (12.5mm) from a good body ground; check if spark occurs while engine is being cranked.

   NOTE: Crank the engine for no more than 2 seconds at a time to prevent flooding the engine with gasoline.

4. If good spark does not occur (should be bright blue), follow the correct diagnostic flow chart (engine and year) and necessary service procedures. If good spark does occur, the ignition system is probably not at fault.
