Need to check the fuel injectors on my 1990 buick lesabre v6 3.8l

You will need a fuel injector testor, about a $100, and a fuel pressure guage, about a $100, to flow test the injectors.

You can ohm check them with an ohm meter to see if one or more has shorted windings. Remove the electrical connector and test between the two pins. They should all be about the same ohms. If one is significantly lower than it is probably bad. Its best to check them when they are hot (after the engine has warmed up).

Map senser location on a 1990 BUICK LESABRE

The sensor is a screen-looking device...located at the input to the fuel injection port. Follow the large air hose from the air should be easy to see once that end of the hose is disconnected.
Try cleaning it before replacing it...I use carb cleaner (generous spray of it directly on the screen). Then reset the Check Engine light (AutoZone can read and reset for you free).

1995 buick lesabre custom. has a new fuel

even if you have preasure in the line that does not mean you have fuel going into the engine. you should check the injectors to see if they are spraying and if not you need to check the injector pulse to find out if the PCM is sending the signal to them to spray. to check injector pulse you will need a noide light to test the pulse it the light lights up you have pulse, but easy way to check is pull an injector and turn the engine over see if it sprays.
