2002 Chevrolet Venture Fuel Rail Parts and Q&A

• Q: How to replace the fuel rail assembly on 2002 Chevrolet Venture?

  A: Note down the eight-digit identification code that appears on the left Fuel Rail before replacement since this rail provides fuel to cylinders 2, 4 and 6. The correct method to install fuel injector o-rings includes placing the black o-ring above the brown o-ring although their sizes match because they have different material compositions. Fittings should receive caps and holes need plugging when you service the device to avoid contamination. First drain the fuel pressure before uninstalling the upper Intake Manifold. Through the process disconnect both engine fuel feed pipes at the Fuel Rail and engine fuel return pipes at the Fuel Pressure Regulator while removing the o-rings from all the pipes. Unplug the main injector harness electrical connector as well as the fuel injector connectors through the lock release up action and lock tab depression. Separate the injector electrical harness from the Fuel Rail before removing the coolant temperature sensor electrical connector. Begin the process by taking off the Fuel Rail retaining bolts followed by the Fuel Rail assembly before moving to remove injector o-ring seals from the spray tips of each injector. The new Fuel Rail assembly requires tilting for injector installation before securing it with attaching bolts which should be tightened to 10 n.m (89 lb in). Complete the electrical connection of the coolant temperature sensor before mounting the injector electrical harness to the rail and attending to the injector connectors by securing their slide locks. Implement this procedure by installing new o-rings onto the fuel feed and return pipes then attaching the fuel feed pipe at the Fuel Rail and tightening the nut to 17 n.m (13 lb ft). The negative Battery Cable receives reinstallation after connecting the fuel return pipe to the Fuel Pressure Regulator and tightening its nut to 17 n.m (13 lb ft). An inspection for leaks should be conducted by first pushing the ignition on for two seconds followed by a ten-second period with the ignition off and then another two-second push of the ignition on before checking for any fuel leakage. This leak test precedes the upper Intake Manifold installation.
