Why 01 honda odyssey wont run when warm until cools down sometimes dies when driving it cools down n starts


the coolant temperature sensor is faulty
when cold the sensor tells the computer its cold adding more fuel into the engine, when warm the engine needs less fuel so the temperature sensor tells the computer its warmed up and to use less fuel. when this snesor goes bad it always reads as if the engine was cold so the computer adds more fuel than needed making the engine not start. Trust me on this ive had this problem happen to me before

Why does my 93 Caravan Start fine and run great till it warms up then dies and wont start untill it cools back down.


I had the same problem a few years ago and it was the coil pack breaking down. If it starts missing before it dies id get a new coil pack. Before u buy a coil pack you need to get it warm again and just before it dies look underneath the vehicle to see if the catalytic converter is starting to get hot, if it is hot and usually getting red hot, its stopped up.It will fool you in to thinking that the coil is bad.

1998 cherokee stall when driving and gets warm ,And wont start till it cools off ?


does your temp gage seem off does it go like up to the h because if it does you could try unpluging your upper coolent sensor because that could cause that because it is telling you computer to run in closed loop when it should be running in open loop

I have a 93 accord lx it starts right up when the engine is cold but after you drive it and it warms up it wont start up till it cools down. i'm thinkin its a problem in the distributor. any ideas?


Have your main power relay checked. It seems to fail when the car warms up and then starts to work again when the car is allowed to cool down.

Vibration at idle


it may be idle control sensor or a bad mas air flow sensor--maf sensor in otherwords. or could be engine misfire at cold temp. start. only time when cold? or does run better when warm? try warming engine to operating temperature before driving,if problem removes it's self after warm up,up grade gas to 93 octane for 1 tank full. then see if problem goes away. it's cold where you are right? if so the fuel needs to be at least midgrade 89 octane fuel because 87 octane fuel will not start your honda correctly at cold temps. in cold weather 93 or super gas octane will start ,no problem,low octane fuel sometimes gels, or freezes at low temps. if in warm climate, change the fuel filter, add fuel injector cleaner to your fuel tank[preferablly lucas fuel treatment] this will lube your fuel injectors and give better fuel mileage. thank you for choosing fixya.com

2000 silvarado 5.3 vortech runs good for awhile after it gets hot it shuts off and wont crank until it cools off


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
