    Default Fuel Systems ~ gm fuel pump problems

    I own a 99 GMC Sierra. It has had major fuel system problems for three years now. As I research ways on the internet to fix my problems, I find this is a major GM issue, not specifically related to my model and year.

    Why was there such a major defect for GM owners regarding something so fundamental and dangerous when it doesn't work right? What has GM done to stop this absoulte abysmal Quality Control issue on newer models? Why hasn't GM opened up Tech Service Bulletins on these issues to let the common man figure out what to do?

    If one searches the internet they will immediately see tons of Fuel Pump failures on GM products. I've already replaced Fuel Pump, Fuel Pressure Regulator and CrankShaft Position sensor and had to finally break down and take it into dealer to get it repaired. This indicates to me that the system is too complex with not enough OBD for the average owner to diagnose and fix.

    The expense and time involved in resolving this has made me have to admit I bought my very first lemon and it was a 99 GMC Sierra. It is so frustrating, I am considering moving over to Ford for a reliable Fuel System alone.
