Tech Tip: Nissan Optical Distributor Test
Many Nissan vehicles have a power transistor controlling the coil (or igniter). The power transistor is a separate unit on optical distributors. It allows the signal sent from the ECU (low current) to activate the primary circuit in the ignition coil (higher current). This induces high voltage in the secondary windings of the coil, providing spark to the distributor cap and plugs. If this transistor is faulty, the necessary spark will not result.

Tech Tip: Ford Diesel 7.3L Injector Replacement Tips
Possible engine damage can result from oil and/or fuel entering the cylinder piston area. Engine oil and fuel galleys run between the fuel injectors in the cylinder heads. When the injector is removed, oil and fuel can enter into the combustion chamber and collect on top of the piston. This will dilute the engine oil and can potentially cause major engine damage from hydraulic lock-up upon starting. The hydraulic lock-up can also cause damage to the starter, flywheel, cylinder heads and valve train components ….
