How do you clean the fuel injectors on a 1993 Buick Roadmaster 5.7L V8?

Get a container of fuel system cleaner from the auto parts store. Outside of that, there is nothing else you can do for injectors except replace them @ about $50.00 each.

The bottles of injection cleaner that are sold and intended to be added to the fuel tank do not adequatley clean the injectors. What is needed is sold in a kit that Napa may carry or Castle chemicals-(off the top of my head). IT is a kit that will attach into a port on the fuel system and run up to a pressurised can. This can is threaded and screws into a regulating valve that will control how quickly the the cleaner is emptied through the hose that connects to the fuel port. The fuel pump is disable by pulling the fuse or relay to the pump. The engine will run directly off the cleaner as it's source of fuel for combustion. Most independent repair shops will do this for you for about $70.00. 6&8 cylinder engines would benefit from 2 cans. Pukenstein@aol.com

What would be the problem causing your signal light and emergency hazard light not to come on?

There are 2 flasher units under the dash. 1 for the turn signals and 1 for the hazard lights. They are round and you need to pull them straight out, then replace them. What I do is I figure out which one works the signals and I replace that one with a heavy duty one, the other can be a regular one. If the lights don't come on but the signals are working it can sometimes be the bulbs, other times it's a short like the other person said.

How do you change the fuel filter on a 1992 Buick Roadmaster?

The inline fuel filter is located under the right frame rail where the right back door is. you will need to jack up the car at the rear jack point, and unscrew the gas cap. Have a rag and a bucket ready in case some fuel comes out. You will need to unbolt the clamp with holds the fuel filter to the frame first. Have the bucket ready, and with your fingers squeeze the quick disconnect fitting on one side of the filter and let the fuel drain into the bucket. Then repeat the squeeze on the other side of the filter to release the other side. Reinstall the clamp which holds the fuel filter to the frame in exactly the same spot as the old filter. Watch the arrow of flow on the old filter and install the new filter exactly the same way. Keep in mind, the vehicle will not run if the filter is installed backwards. Fuel flows from the gas tank (back) to the engine ( front). Make sure new filter snaps in to each fitting well before bolting the fuel filter down. Once this is complete don't forget to screw the gas cap back on and start the engine to make sure there aren't any leaks.
