I have a fuel leak on my 97 blazer 4.3 (W) motor. The 12 wire connector that plugs into the top of the injector housing is leaking fuel all over the top of my plenum. The boots on each of the wires are wasted and fuel just leaks right up through the connector. The truck runs fine, but I have noticed a decline in gas mileage. I hav'nt pulled the upper plenum off yet but was wondering if anyone knows what exactly would cause this problem. Could it be Injector seals, fuel pressure regulator, the connector itself, or a combo of them. I also have two bad O2 sensors that need to be replaced will this cause any fuel presure or metering probs?
have the same problem?
