How to Install a Fuel Injector in a 3.5L Engine on Dodge Challenger?

Lay the fuel rail over the cylinder head and snap it in place, using 11 Nm (100 in. lbs.) torque when mounting the fuel rail bolts. Connect the quick connect fittings of the fuel supply tube at the back of the intake manifold and join the electrical connectors to the fuel injectors. Set the intake manifold plenum on the engine and afterwards connect the negative cable to the battery. Once done, you should use the scan tool to increase the fuel pump's force and search for any leaks in the system.
