01 blazer. Started running bad. ive replaced the fuel pump wires cap plugs and the o2 sencor. From suggestions?? The truck runs fine for the first 2 or so mins. then just starts dumping fuel? Or is the ignition breaking down and not burning it? i didn't use ac delco parts. i read i should have!! The first time i had the codes read it was pretty much every sensor. i took off the batt terminal and reset the ecm. Now the only code is bad injector #6??? I'm lost and broke. any help would be great!!!

 

Could this a crank shaft sesnor prob?

 

If the code says it the fuel injector #6, why would you think its not that? Perhaps the injector needs to be replaced?
