Steam cleaned engine now wont start - 1986 Toyota Tercel

White smoke is steam. Check compression and check for a cylinder head water leak.

you look for the problem.

I guess my first question is, have you checked the computer for trouble codes ?
With water on the engine the problem could be a long list of things including water in a harness connector.
Even the plug wires could have been damaged.

Well I don't know about the rest of the problems but the heat and steaming more than likely is Ur thermostat. I would change that out to start if steaming continues I would look into a water pump. But start with the thermostat and go from there. Hope this was some help

YES,you steam cleaned the engine,it may right itself after drying out(hopefully)when you steam clean, the water particles are much smaller than a normal "hose down"so you may have wet the electronics.if it starts, then let it run for awhile to (hopefully)dry out itself.

Take care of cranking 1st, check battery see if it's good, try to get a jump start see if it will turn over, could be a bad alternator or battery.

If you steam-cleaned, the vapor seeps into the electrical components and causes problems.

The advice folks hear around the repair shops is: 'Never steam-clean an engine'

If you hosed it down, the stalling may clear up pretty soon.

Rain Does NOT DIRECTLY Get into Engine Comp.
Eng. Electronic Components Must Be DRYED With High Pressure AIR After Steam Cleaning

Some of the grime, etc on the engine prior to steam cleaning along with any solvents used may have affected the drive/fan belt. I would suggest you either check tightness of the belt and possibly consider replacing it.

Most likely you will just have to wait for it to dry on its own. It is best to wash a engine while it is running so the ignition components stay dry.
