The Nissan 350Z was a famous car model representing a sports car and marketed by Nissan from 2002 to 2009. The engine used in the 350Z implements with direct injection technology helped maintain powerful performance with improved fuel efficiency. The fuel injector, in this type of engine technology, is placed directly inside the combustion chamber, rather than the intake manifold. This modification helps improve fuel efficiency by reducing choke losses, compared to an ordinary MPFI system. But this upgraded version of the injection system will also become ineffective if the fuel injector becomes damaged or clogged. Since you are restricted from spraying the required amount of fuel, it will directly affect the performance of the engine, causing it to run sluggishly. Making your switch to your 350Z replacement would also need you to keep the replacement clean, without any additional cost or damage. To make sure this replacement remains effective on your Nissan 350Z, follow these simple steps:

1. It is very important to choose the right injector for your 350Z; otherwise, there is no point in replacing it with one that does not fit the engine requirements. The 350Z model built between 2002 and 2006 was powered by a 3.5-liter “VQ35DE” engine. While the 350Z Coupe and Roadster versions, made in 2007 and 2008, featured a “VQ35HR” engine. Know which engine fits your 350Z and, depending on the engine, buy a new injector.

2. The next step is to remove the old and damaged injection element, using a socket wrench set and a replacement set, which would help you easily remove the element from its place. For this, you will first need to disconnect the negative terminal of the battery and then remove the fuel hoses from the fuel and the electrical connectors. Before removing the hoses, be sure to remove the pressure within the fuel system by removing the fuel pump fuse or relay, with the engine running.

3. Disconnect the vacuum hose from the fuel pressure regulator. Now, disconnect the fuel rail with a socket wrench to remove the mounting bolts. This will pull the fuel rail off the engine.

4. It just requires a little push to remove these injection fragments from the rail. Once they have been removed, remove the o-rings as well and do not reuse these seals.

5. Install the new fuel injector to the fuel rail with a new O-ring and reconnect the fuel rail to the engine. Connect the fuel hoses and battery cable to complete the installation process.

6. Connect the vacuum hose to the pressure regulator and also connect the fuel pump fuse or relay in its place. Finally the engine starts. This will bring the pressure back to normal within the system.
