Question about 1992 Buick Park Avenue
Engine turn over but will not start
Sounds like a fuel or spark problem. Check your fuses first. If it is not a fuse you need to determine if you have enough spark and enough fuel arriving at the spark. First pull out your number one spark plug and check the spark and gap to rule out the need of new (or cleaning of old) spark plugs and/or ignition system (i.e. ignition wires (you will need a spark plug gapping tool for this)). If that has been ruled out then remove the injector rails and try a quick turn of the key to determine if they are delivering fuel by noticing if the fuel squirts out. If you have little or no fuel coming out (it should squirt hard) of they injectors you will then need to determine where the stoppage is (whether you need injectors, fuel filter, fuel pumper or any combination including all of the above). If you determine it is a fuel problem check the filter if it is blocked or dirty replace it. If it is not the filter then change the pump. If it still does not work you need to clean or replace the injectors. Replacing is suggested, the fuel injector cleaners are not good for other components of the vehicle and also are not good for the environment. Of course I write this under the assumption you have fuel in the tank.
