How many fuel injcton does a trilblazer have?
If the Trailblazer is a four cylinder vehicle, then there are four fuel injectors in the car. They are located right on top of the engine behind the valve cover and under the throttle body. You can find the injectors for your car at many auto parts stores locally.
It depends on what you mean By How Many. If you mean how many difrent parts make up the fuel lines I need to know Year, Transmission and Engine type. If you mean fuel line assemblies there are two. Presure line from tank to fuel injection and Low pressure return line to tank. There are several other lines that look like fuel lines that are for the fuel tank vapours.
