dumping fuel???

I've changed the CPI Unit, Fuel pump, the EGR Valve, map sensor, coolant temperature sensor and control module. New timing chain. New plugs but it's still seems to be dumping fuel and fowling plugs out quickly. Any ideas what else to look for????

Did you scan the vehicle to check the sensor parameters? One of your sensor is out of spec causing the your "fuel dump". Scan the vehicle and let us know.

Hey PVC
I have a 92 Blazer with a 4.3 v6 vortec engine in it and it is dumping fuel in the oil.. After turning the engine when trying to start it up the engine locks up and I have to take out the plug. The plug are very wet with gas.Do that sound like a sensor as well.

What do you mean when you say scan the vehicle? I've looked to see if any visible signs.

Hey amac209

You may have a point. One of my injector line has turn white. Is that why it may run hot in traffic on a hot day also.
