SOURCE: need diagram of engine to replace fuel filter on

The fuel filter is located inside the frame rail, just ahead of the passenger-side wheelwell opening. It has a threaded fitting on the forward end, and a quick-release clip on the back hose attachment.
Caution! The fuel is under pressure. Wrap a rag around the quick-release fitting as you release it, to catch any spray. or first relieve the pressure at the test port on the injector fuel rail (under the plastic engine cover), again using a rag to catch the fuel spray. Wear safety glasses, and only do this when the car is completely cooled off. You WILL spill some fuel while doing this, so have a catch container, and/or spread oil-dry/cat litter on the ground under the filter area. After changing the filter, turn the ignition "on", which powers up the fuel pump, but do not start the car. Now check for leaks at the filter, and at the test port, if you used it to bleed off fuel pressure. If everything is dry, you are OK.

Anyone have a 1995 Buick lesabre custom, ignition wiring diagram?


Insofar as your Ignition Wiring Diagram, I hope you're speaking of what's also called the Spark Plug Cables or Firing Order. The proper Firing order for your V-6 is 1-5-3-6-2-4 with the number 1 cylinder being the front spark plug on the left hand side. The left hand side is Odd numbered and the Right hand side is Even numbered, therefore number 2 cylinder is the 1st plug on the right hand side of the engine.
