I just rebuilt the top end of an 89 pickup(22re, 4x4) which hadn't ran in 4 years. Upon reassembly every thing worked fine, but after idling roughly for about 2-3 minutes there was a definite "ping" followed by a large cloud of white smoke from the exhaust. At first I thought a water or oil port had cracked, but the oil is clean and the water level constant with no blowback. The motor is trying to run and is smoking like an injector(or two) is stuck open or like a diesel with a bad fuel pump. The smoke is white but does not smell sweetish like antifreeze, but smells very strongly like unburned, atomized fuel(similar to cold starting a diesel). I checked the injectors today and they were clean. Could this be a problem with the cold start injection pipe sensor, or the throttle position sensor? Any help on the matter would be greatly appreciated.

Unhook the csi to see if it helps. How old is the gas? Plugs? Wires? Air filter? Is the timing correct?

Injectors can dry out if they set for a period of time. They can look fine, but be bad on the inside. You can pick up a set fairly cheap used, and witch hunter can recondition them for about $20 per injector.

I pulled the injectors out, tested them, and cleaned them with seafoam, everything was in working order. The gas, plugs, wires, and air filter are new. I'll put the injectors back in tomorrow and try starting it with csi unplugged.

I'm getting smoke now also I have a 82 22r with 157000 miles and I can give it gas and on the declaration it blows white smoke, it's not a whole lot but it's enough to aggravate me. My oil is not mixed and I'm not loosing coolant and to me it smells like gas but it burns my nose bad, any ideas of what this could be please try and help and will update on progress thanks
