2000 Chevy Tracker will die after being driven for a short while, it usually takes anywhere from 30 minutes to a few days for it crank back up. It usually doesn't run but 5 to 10 minutes. When it does run it has a small amount of white smoke blowing from the tail pipe. Not a heating problem as everything associated with that has recently been fixed or replaced, along with coil packs, relay switch and crankshaft sensor.

LITTLE WHITE SMOKE NORMAL WHEN VECHICLE FIRST STARTED IN THE MORNING,WHITE SMOKE WILL DISAPPEAR WHEN ENGINE GET OPERATING TEMPERATURE.CHECK FOR FUEL PRESSURE COULD HAVE STOPPED UP FUEL FILTER, BAD FUEL PUMP RELAY OR FUEL PUMP FAULTY BAD CONTAMINATED FUEL WILL CAUSE ENGINE TO STALL OUT.

I figured out the phantom problem in a 2001 tracker with a 2.5 ltr
it was the idle control valve or iac. the part inside that has a stem gets worn and falls loose and closes the air passage. because the iac electrical part is still working the pcm thinks that it is working fine. if u remove the iac and leave it connected to its power then turn the key in the truck to on position not start position but on position. do this for a few times and if the part is worn it will fall out. i feel that any one with a tracker who has the mystery stalling and starting problem. might want to have a closer look at the iac. especially if u have rpm issues when the inside car fan is turned to its on position. spread the word and save a ton of money on this one nidle in hay stack found!
