Do you mean wont crank over and start till it cools off? if thats the case it sounds like you got a bad crankshaft position sensor,,thge sensor is fine when its cold and warm but when it gets hot it goes open and the cars computer cant see the rpm and shuts the engine off,and then when it cools off the sensor works again and the car starts and is ok till it gets hot again,if thats the case thats what it is,,,hope this helps,,,about $100 for the part

Runs fine until it gets warm or hot then cuts off then cools and will recrank


Does it crank over when the engine is hot. If it does sounds like your maybe loosing fuel if so check fuel pressure if t is good check for spark could be a bad crank sensor or bad distributor.

Is there a heat shield on the starter


I don't think there is a heat shield on the starter but, I wouldn't think that would be you're problem. I would try changing the ignition module. It's on the engine block, drivers side, I think. Usually when they are going bad they will shut off engine when they get hot. It won't crank until it cools off. After it cools engine will crank and run good until it gets hot again. Good Luck.

Car starts fine maybe a couple of cranks but nothing serious, runs really good after starting, can drive it all day.But when you shut it off, it dosnt want to start,untill 5 or ten minutes go by than it...


Hi and welcome to FixYa!

As a first course of action, I strongly suggest that you replace the ignition coil. If the ignition coil gets hot the car may stall or may not start right away till it cools down. The ignition coil is surely faulty and replacement is surely necessary.

Hope this helps and thank you for using FixYa! Have a good one!

Is there a thermostat shut off switch . car runs


The amount that it gets hot is a clue but theres no shut off switch. It's possible that the car is over heating and the temp gauge does'nt have enought water over it to report the problem. once the cooling system is cleared as it's full circulating and the fan will come on when it's hot ( disconnect the temp. switch on the therostate cover on the top of the transmission, ( the stat is in the lower hose ) with it disconnected and the key on the fan should be on and connected f till it's real hot. The crank senser or distrubutor module can can too hot and shut down too

My 2000 acura 3.2 tl is misfiring. I've replaced the spark plugs. It starts and drives fine until you park for 5 minutes and when you go to start it up again, it misfires badly and sometimes won't start at...


Check the wiring. to Coil, plugs, Crank Positioning Sensor. check to see if the wire is in good condition sometimes if wire is checked, in poor condition it will allow bleed through especially when the wires get hot. This is why it will often start when engine cools down and why it shuts off when your sitting cause it heats the wires up there is not the cool air running accross the wires when sitting. Good Luck and a grt day. Would appreciat 4 thumbs up if this was helpful.

On my f150 5.0 it starts good cold but after i drive for awhile maybe 5 miles i shut it off and start it again it is ok.But if i wait 15 min it wont start.you can try but after it cools off it will start...


It could be a spark plug problem..I would remove a few of them to see what they look like. It may not be firing very well when it gets hot, and new spark plugs are never a real bad investment, since they're generally very cheap. Not sure on this, but it's a good place to check.

My 91 civic runs and drives good but sometimes i shut it off and it wont start back up 4 awhile and then i hear a click and it starts back up please help


check your solenoid on your starter, usually when it get hot it fail until it cool off. a sign of starter going bad if you have to wait til the starter cool off before you can restart the car again. also check contact to the starter. if you having problems getting the starter to work you can get a small hammer and lightly tap the starter, 90% of the time it will kick over.
