93 Trooper White Smoke

I had my 93 Trooper recently start blowing out white smoke (not the thick stuff). 3.2L, V6, LS, 120k.

A recent history:

Car driven from Seattle to Portland 3 weeks ago no problem (over 300 miles). Sat at a body shop for 3 weeks (just body work was done). Took the car home, on the way it died (blew out a large puff of black smoke).

Put gas in it (it was low, and still is); jumped it; and drove it home.

Started the car and let it run -- white smoke coming out exhaust (not thick) but definately white (or light blue).

Check engine light is on.

Questions:

Might this have to do with the EGR? Water in gas, since it was on E for a few weeks? Or that it needs new belts (basically a tune-up) minus spark-plugs and wires which I changed in August.

Thanks guys.

If the check engine light is on, then a code is set, and you can find out what is causing the light. The EGR system is code 32.
You don't mention temperature but if the smoke is not condensation from running, then white smoke is sometimes indicative of coolant leaking in to the combustion chamber, either directly past a head gasket or through an intake manifold leak.
Light blue might be a little oil blowby past the piston rings, which on a vehicle with miles is not unusual. Again, consumption of oil and the oil condition can be important clues.
Cleaning the EGR is not hard, but the port to the intake can be a little awkward due to its narrow width and long length. Some carb cleaner and a small bristle brush will usually help. Check all vacuum hoses and line for their integrity while you are at it.
If the smoke goes away after a while, it may just be normal moisture, but if you have to add coolant or the oil is getting a milky appearance, then coolant may be leaking.
I would be surprised if this is your problem given what you have said. It is never good practice to leave a tank empty for a long time, so I suppose it is possible that a slug of water from condensation may have caused some problems. Gas line deicer will also help remove water from the fuel system.
Hope this helps, good luck

Okay. So I drove down the block and filled it up with gas (full-tank) and brought it home. No problems.

Later I drove it about 3 miles up the rode to run an errand. When I went to get back in the car it wouldn't start. The engine would turn over but nothing happened. I left it. A couple of hours later I went back, started it up, and drove it home.

Any ideas?

Kermit']...Any ideas? the best idea would be to do some basic diagnosis/troubleshooting when it happens (doesn't start) to try to narrow the issue down to fuel or ignition, at least.
otherwise we are all going to be all over the map on this, unfortunately. maybe you can *try* to duplicate the situation again and be ready.

bummer, though.

I think my issues may be consistent with this following thread:

I'm going to follow up with the recommendations made there and re-post in about a week or so.

ok, thanks. remember he has an earlier, different, engine, etc.

I had it looked at and was told that I needed a new temperature sending unit.
