Driving car died wont restart.engine covered in oil.

Sounds like you damaged the engine by running it without oil. Sorry but you probably need a new engine.

well lets try inspecting your coolant temp sensor for the ecu, not for your gage it is green whit two wires going into it, if any corrosion replace sensor and pigtail, your ecu may be dumping lots of fuel thinking eng still cold when is hot, this also wahs off your rings and by adding oil bumps compression and starts, hope this helps.

Sounds like your alternator went bad. The battery ran down after awhile and now it won't restart because your battery is too weak. Have the alternator checked and if bad, replace. Charge or replace the battery and that should fix it.

milky oil means water/coolant is mixing into the oil, most likely cause based on the described symptoms is a blown head-gasket

Do a compression test. Your engine may need an overhaul.

Wiring the electronics can be tough. I would go to a <a href="http://www.excel160.com">professionalo</a>.

I think you had better have a local shop inspect this for a failed engine connecting rod.

Sounds like the timing chain broke. TJ

Hello Friend,
Pull out the spark pugs so, there is no longer compression. Put a wrench on the crankshaft pully. The engine will turn and the pistons will travel up and down. This is of course it the engine hasn't seized. If the engine turns its the starter. Simple.
