My blazer has been haveing fuel pump issues since aug. Its now march and two pumps later im still haveing problems! So before my question a few facts. The second time I changed out the pump I found that this problem lied in the wireing harrnes because I had to switch out the harrnes as well as the pump. After I switched the whole thing out I now have no power in accelerashon my service eng soon light is on and on hills at the peak of R.P. Ms my battery light comes on. My questions is how can I get to the root of the problem? And is this all conected in some way? Thanks for the time -Nick

Where are you getting these pumps and why do you need to keep replacing them? No pressure? Have the PCM (computer) scanned for codes, Autozone will do it for free. If the PCM sees a problem it will store a code that will help in diagnosing the problem, get back with the exact codes.
