When the bad injector is blocked off, the fuel pressure at the rail will increase and your engine will start..【Note】In some situations, it can be useful to have multiple block-off tools, because multiple diesel injectors returning a small amount of diesel fuel will display the same symptoms as an individual diesel injector returning an excessive amount of fuel..【Satisfaction Guarantee】 Provides a 100% satisfied after-sales service.
