I have a tbi 220 2.8 blazer. One day one of my fuel injectors went bad so I replaced. Well a few weeks later the same injector shorted out(pouring out of the end) again. So I figured it was just a bad one or was clogged etc. Replaced again. Well a few weeks later happened again. Remember this is the same side injector not the other one or both. SO I replaced and this time switched the wires to the other injector and vice versa. Well 3 weeks or so later it happened once again but now on the other injector where I switched the wire. So now I have a short somewhere I am figuring. I am being told to drop the gas tank, change out the fuel pump, fix reground the ground, then change the fuel regulator, and if that doesnt do it, change the pcm and or o2 sensor. Man thats alot of money. How can I find out what is causing this without having to spend 800.00 first?
have the same problem?
