Car runs and engine gets hot. once you turn it off and try to start again.engine turns but wont start. leave for 10-15 minutes than you can start.

If the anti theft indicator remains on when you turn the key to the on position then you'll need to reset.

To reset the system, get in the car and shut the door. Turn the key on to the "Run" position without cranking the engine. Leave in run position exactly 10 minutes. Turn the key to the off position without removing it and back to "Run" for 10 more minutes. Turn the key off again and back to "Run" for 10 minutes a third. Turn the key off and then attempt to start the engine.

C190 is a 2.0 L OHV 8V engine same as marine 4AA1.
when warm did you try diesel test fuel?
runs now , right, or runs and stalls. right?
that be the biggest clue there.
besides black smoke.
lost compression hot.
or lost fueling hot.
simple test for compression and test fuel....... leaving what?

If the security light is hot or flashing when the key is in the on position, most likely the ignition key tumbler housing has failed.

You can try resetting the pass code by turning the ignition switch to the on position (do not crank or start the engine). Leave the key in the on position for 10 minutes. Turn the key to the off position, wait 5 seconds and turn the key to the on position again and leave it on for 10 more minutes. Cycle the key to the off position again for 5 seconds the back on for a final 10 minutes. Once the final 10 minutes is complete, turn to the off position again, wait 5 seconds and now turn the ignition on and to the start position. The pass code has now been reset and it should start. If the reset does not work you will have to change the ignition key tumbler housing that contains the key code resistor.
Good luck

1. When setting the temperature to MAX, blower level to FULL and outside air Vent CLOSED, no hot air comes out after 2-5 minutes?
If YES, when did you last flushed your radiator and is it full?
2. if more than 5 years ago, flush radiator system, instructions are usually in Owners manual. Use a bottle of Radiator cleaner, run egine hot for about 10-15 minutes, carefully open petcock in bottom of radiator to flush out radiator, WARNING, careful as flushed coolant would be boiling hot. As sson petcock is open and water start to flow out, carefully open radiator cap to enhance flushing flow. Use garden hose to fill radiator while flushing until water coming out from petcock is cold and clear.
Once clear, start engine, turn heter full and blower full blast and keep hose in radiator flowing full, leave petcock open until clear water flows out again. Once clear waters comes out, turn off engine,turn off garden hose and let water drain empty radiator. Once it stops flowing out, close petcock snug and put radiator cap on, pull off radiator coolant catch bottle, clean bottle for any debris and dirt. Drain any water, leave bottle empty and put it back onto its place.
3. Fill radiator with 1 gallon (4L) of concentrated coolant, top up radiator until full, fill catch bottle with concentrated coolant, start engine and keep it overflowing until no bubbles comes out and the radiator is fully hot. Once it is flowing good, close and connect everything. Drive with it and keep catch bottle filled as necessarry.
Good luck. Give as vote and good comment if this advise solve youor problem. Thank you.

hi, you can perform the reset with just your key and a battery charger to see if this will allow for restart. what you do is, hook up a battery charger to start with, low amperage setting like 15 amp, or maybe 2 amp, and leave it on the battery, you will be leaving the key on for up to an hour and the battery must not die during this time. turn the key on and try to start once for about 1-2 seconds, then let go and let key rest in run position for fifteen minutes at minimum. then turn off the key, wait ten seconds, and turn on again to run position only, leave on for another fifiteen minutes, then again, turn off for ten seconds, turn back on to run position for fifteen minutes. after this time, turn the key off, wait ten seconds, and try to start the car. if it starts, check to see if the check engine light is illuminated, or the security light is on, if one or the other is on, take to a shop and have codes checked and diagnosed, if no lights on, you should be able to drive on. if the vehicle does not start after three reset key cycles, try the process one more time. it may have been interupted somehow. if you try twice and still no start, you have to have diagnosed further, maybe in the key, maybe in the lock cylinder, maybe in the theft module.

I HAD SAME PROBLEM, ENDED BEING CRANK SENSOR GETTING WEAK, AFTER HOT THE CRANKING SIGNAL IS TO WEAK TO TRIGGER FIRING.

sounds like coil problem, coils will start cold then get hot and stop. when coil cools will crank up and run till it gets hot, try to replace the ignition coil,dont think it would be a crank sensor, try a coil,thanks robert b.

Is your security light flashing ?if so you have a problem with the anti theft system.Leave the key on for 10 minutes ,then try this should reset the anti theft system

Be sure its all the way in park or try neutral.Its possible that security system does not recognize the key. Is security light flashing or on steady? Shut all doors and windows,trunk,hood, turn off all accessory's,roll down drivers window, turn key off and remove for at least 1 minute, insert key into ignition, try to start leaving key to run position for 20 minutes, turn key to off,wait 15 seconds, try to start again leaving key to run, wait 20 minutes, turn key off,wait 15 seconds, try to start, again leaving key to run, wait 20 minutes, turn key off, wait 15 seconds, try to start. This should relearn key code. It may relearn after 1 learn cycle and start if system is ok. Hope this helps and that the weather is dry and warm for this procedure! This is not always a fix, but works most of the time.

It sounds as if the crank position sensor is bad.When the engine heats up,it cases the sensor not to work.After the sensor cools it will work again.
