PERFORMANCE ORDER
1. Disconnect from a fuel nozzle the electric socket and, using an ohmmeter, check resistance of a winding of a fuel nozzle.
2. If resistance of a winding of a fuel nozzle differs from demanded or there is a short circuit or break, it is necessary to replace a fuel nozzle.
3. Measuring resistance of a winding, serviceability of an electric chain of a fuel nozzle is checked only. Thus the torch of dispersion or productivity of a fuel nozzle is not checked.
4. If there is an assumption that the fuel nozzle is faulty, it is possible to try to replace a fuel nozzle with the obviously serviceable. If the replaced nozzle works unsatisfactorily, it is necessary to address on Opel service station for complete check of system of injection of fuel.
