Note: The test information in this section only applies to engines equipped with a conventional ignition system, i.e. to all engines except 1.6L engine with multiport fuel injection (C16SE).
Due to the use of an electronic module/ignition coil assembly on this engine, tests must be carried out by special instruments and by Vauxhall/Opel vehicle repairers.
General provisions
The general points above apply equally to fuel injected engines, however, it must be remembered that extreme care must be taken when testing this system, as the electronic control unit is a very sensitive device and damage can be costly.
Engine won't start
Check for damage to the ignition system by following the procedure described above in the relevant subsection for carbureted engines and check the HV circuit.
If the high voltage circuit is not damaged, you can check the current supply to the ignition coil, as indicated in the subsection for carbureted engines. Do not forget that the electronic control unit controls the power supply to the ignition coil, you should not try to check the electronic control unit with any devices that are not designed for this. Vauxhall/Opel car repair specialists have such equipment. If you need to check any of the wires that are connected to the electronic control unit (although not recommended without proper hardware), always disconnect the corresponding contact from the control box first (with the ignition off).
If all components are checked, but the system does not work, you need to contact specialists.
Interruptions in the ignition system
Follow the instructions in the appropriate subsection for carbureted engines. However, keep in mind that there are many causes that can cause misfiring, so that they can be eliminated without the use of the appropriate equipment.
