Question about 1998 Pontiac Grand Am
The #3 fuel injector does not cut off. there is no blinking on and off with the
elec to the injector. there is just a steady light.why is it not cutting off
Initially, the ECU/ECM (engine control management) is to be suspected. Chances are the servo/drive transistor that switches the fuel injector on/off is shorted and therefore there is constant power supplied. Am not sure if service shops in your area would do component level repair, but it is possible just to replace the discreet component(s) that may be defective. Often, to my understanding, repairs involve replacement of the entire unit/assembly.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
