stalling problems

i have a 95 lesabre ltd with a 91 motor the problem im haveing is that when the car heats up to 200 it stall with no warning i have checked the thermostat and to make sure there was no air in the fluid lines i was thinking it may be the ignition module but im not sure there are no heck engine lights kicking on when this happens im not really sure what else to do the car only restarts after it sits for twenty minutes

You should check for spark when it quits.
Then think of troubleshoot the ignition system it theres no spark.
Or troubleshoot towards the fuel system if there is spark.

we checked for spark when it quit and there wasnt one but it also has three coils that are bolted on top of the ignition module im just confused ause a friend of mine said there is no way it could be all three coils at once

I agree with him.. unless a coil dead shorts its primary coil. That may disable the whole module and they are SUPER easy to swap out.

After a failure you may want to feel each coil and see if one is hotter or colder than the rest. This may not help but may provide a clue.

Since you say it sits for 20 min and starts, you could douse the ignition module with cold water and see if your car starts. That would help identify a hot ignition module, now cool, works again.

To swap out the coil takes about 3 minutes.
Ignition module 30 minutes.
CRanksensor 2 hours.
All with proper tools of course.

Popular temperature failure issue items are
Coils, ignition modules, CRankshaft sensors.

Ignition module is the next easier item to change.

The Crankshaft sensor is a suspect. It talks to the ignition module and then back to the PCM where the PCM controls spark advance according to RPM and then tells the ignition module spark time.

Good Luck

I had an 87 that would not start after being driven, and started after cooling off. I found the radiator was clogged, causing it to run hot, but not hot enough to give a temperature light. When I parked, some component got hot enough not to work. Changed radiator and had no more problems.

ok so i changed the coils and the ignition module still stalling out what else is there for the ignition system i had the car scanned at advance the codes im getting are as follows currant code p0361 ign system problem elec spark timing EST not toggling history code p0300 misfire signal misfire detected history code p0321 ign system problem 18x interrupts lost signal history code p0341 ign system problem camshaft sensor intermittant signal a friend of mine is saying it may be the brain i bought the ar from someone else the motor is a 1991 the rest is a 1995 any one that can help i will appreciate it

Agree 100% with HotZ

Intermittant no spark is usually ICM or Crank Sensor. Once you rule out one it's time to change the other. Another possibility is the wiring between the crank sensor & ICM but my money is betting on the sensor.

this may sound dumb but where do i find the crank sensor in the engine im not very car smart i can take it apart and put it back together again i just dont know where everything is i would buy a book but im out of funds
