Question about 2002 Buick Rendezvous

Open Question

Once my 2002 Buick rendezvous gets hot it won't start till it cools down. It's not the starter the car cranks away but won't start. Also not the fuel pump because if I don't turn it off everything's fine. Forget about any diagnostic codes, Buick dealer told me there is nothing he can find. I believe there is an engine temp sensor somewhere that is not working.

SOURCE: I have the same exact problem, once the 2002 Buick

Hi usually the symptoms your having are a result of the oxygen sensor(or lambda sensor for its technical name) being at fault.

now the reason it points to this being at fault is that it only starts working when the engine is near normal temp then if the car wont start till its cooled down then this is because the sensor then stops working when its cooled down so your car will run again until it gets hot,

you need to check where the sensor is located in the exhaust if it comes before the catalytic converter then the chances are its the sensor at fault but if it comes after the cat then it could be the cat that is at fault.

my best guess would be the sensor as your car is playing up exactly as if this sensor was not working.

i hope this is some help to you

let me know if you need further assistance ok

plz rate this solution as i have a whole page of unrated posts, thanks

My 02' Buick Rendezvous cranks too long or doesn't start if you turn the key from the off position to the start position immediately without waiting in the accessory/on position for about 2-3 sec.


Check your fuel pressure, it sounds like your fuel pump is slow to build up the pressure, or maybe pressure regulator is not holding fuel pressure the way it should.

My 1988 buick century stall,s after driving. engine warm,s up.won,t start right after stalling.start,s after sitting 10 or 15 minutes


Possibly an ignition module or crank sensor problem. These are the two most common stalling electronics that will cause a stall when they get warm/hot and will then continue to operate once cooled down

02 Buick Rendezvous won't start


Does it crank but won't start or is it a crank no start? Does the starter solenoid click or no click is heard? You need to state in detail what sort of testing has been done and the results along with detailed symptoms in order to help you better.

Wont start when hot


The starter is effected by heat. Does the motor spin just as fast when trying to start it when the motor is hot? If it cranks real slow it is the starter. If it cranks over at the same speed it is not the starter.

Get an account on a mini cooper forum and post the question there. you could also try a small spray of starting fluid into the air cleaner. If it starts and stalls then it is a fuel delivery issue. If it does not start then remove a spark plug and verify that there is a spark as the motor cranks over. Check for any blown fuses.

Bad cam shaft senser


You could have a faulty engine coolant sensor or intake air temperature sensor. Fuel injectors clogged or dirty flooding engine.
Clean fuel injectors, replace fuel filter and air filter, and see if the problem persists.
If it does ECT sensor is bad. If CMP sensor was bad, the vehicle won\'t start whether cold or hot. CKP senso and CMP sensor work together if either one fails, the vehicle won\'t start. Have the vehicle code scanned.

Does the engine turn over good? If so you may want to have the crank shaft position sensor checked out. Also check for fuel making it to the engine. You should have a fuel rail which is chrome looking that runs on top of the engine. Look along the rail for a valve stem that looks like what is on you wheels. You may have a cap on it, but either way press the stem and see if gas squirts out, if not you're not getting gas up to the rail.
