Symptoms of bad or Gelled fuel

unplug the crank sensor, see what happens. If the OS really isnt working it wont start or run.

Also try unplugging the coolant temp sensor on thermostat housing, see how it starts and runs. It will think its really cold s should be at a higher idle, and advnanced quite a bit. Then try jumpering the sensor harness with a paperclip or something, so the truck thinks is hot, which will also advance it some and raise idle a little.

I'll try that tomorrow. Went outside again. Fired right up like normal. No misfiring, coughing, etc. SES light was still on but that's all.
