White smoke from TBI?
 
Hey TGO,

I tried starting my parts car w/ potential and she ran REALLY REALLY rough. As I backed it in the driveway it cutoff like someone pulled the plug. I jump started it again, it ran like crap again for about 45 sec or so and I happened to notice some white smoke came up from the TBI, almost like an thin mushroom cloud as it died. I know the car has sat un-started for some time but when checking the Oil it didn't look like sludge or milky. When checking coolant it was as green as any other 50/50 coolant, When the weather breaks i'm going to pull plugs, check wires, cap & rotor button, etc but in the mean time I was looking for any of your experiences starting cars that have sat 6mo +

Now that I typed this up, it's almost like the plugs aren't burning off the fuel being supplied...

Any direction or input would be appreciated, Thanks.

Although it's still freezing out here in ohio, I did do another quick once over and realized the following was disconnected...

- Vacuum Line to Coolant Bypass Valve
- IAT Sensor

Reconnected IAT Sensor & Vac Line & Changed the Blown 20A ECM/FP Fuse. Battery is indoors on charge, will report back when it's above 40 degrees.

Update: Matter Resolved

Couldn't wait until a 40+ degree day so a bit ago I grabbed the battery off the charger and hooked it up. Tried to start, 1st two times were rough but it started, ran a bit smoother and NO MORE White smoke from the TBI. I now conclude the disconnected Vac line and IAT being disconnected & overlooked on my part was causing a quite critical rich condition, etc, etc.

Could be bad gas too. It really doesn't have a long shelf-life. :D
