my accord would do that, i would hit the dash hard and it would start right up ghetto but it worked. it is caused by the fuel pump relay up inside the dash or it was im my case.

does it try to start (like kick over and all) if you try it right after you shut it off?

fuel pump is going bad. its telling you its going bad by acting up when hot. underneath your rear seat you'll find it. 135 dollar part. replace it before ur car just shuts off when ur goin 65 on a highway

you should be able to hear the fuel pump click on and run after you turn the key on...

yeh i do hear it ^ doesnt that mean its good? a buddy told me it could be a coolant temperature sensor?

The fuel pump will not shut down when the car is "Hot" it is powered electrically and has no relation to how hot the engine is.

You can check by putting your ear near the gas tank and cycling the key forward. Listen for the whine of the pump. If you dont hear it, the fuel pump is not working. Hit the gas tank with a plastic mallet to see if it will intermittantly kick on.

What it might sound like is you need to take it to a mechanic. there are a million possibilities why it is doing this. It is also very hard to diagnose a problem like that over the internet.

a coolant temp sensor only affects the gauge inside of your car (what makes the gauge go from C to H). That also has no effect on your problem.

wrong...

it might actually be this sensor, we have a buick that runs great after you first start her, but if you shut her off and start her up again while shes hot, it runs like ****. I think the temp sensor is bad on it.

no. you can disconnect the sensor and the car will still start and work fine. The only thing that wont work is your temperature gauge inside of the car. All that sensor does is tell you how hot the engine is.

there is such thing as an intake air temperature sensor. that could be a reason but the MIL(check engine) would be on

does the same thing. If you unplug it the car will go into failsafe mode and operate regularly. but if that sensor is bad check engine would be on. and btw it is the same exact thing i was talking about in the beginning. it just provides temps to the car and pcm.

um...if your temp sensor is unplugged, or not working correctly, you car will NOT run correctly.

OP, unhook your battery for a lil bit...then start her up and see if the CEL comes on.

The PCM detects that, and it will go into failsafe mode. It will run. All that sensor does is tell the PCM how hot/cold the engine is so the PCM can make up for it (such as idle when you first start the car, air intake and fuel delivery) It does not matter anyways, the MIL is not on, so that sensor is definitely not the problem. Take it to a garage.

no i mean literally hit the dash pretty good, right above the gauges, once that relay gets warm then starts to cool down it doesnt like to kick back on right away.

mine would sputter then just crank on a hot start if it had sat for less than 5-10 mins.

no ish...i wasnt saying the car engine being hot....anything run with electrical is going to produce heat.
Occasionally, a fuel pump will warn you that it needs to be replaced. It will overheat and stop working for 20 minutes or so. If you let the car sit for a half hour (more or less), it will start again, as the fuel pump cools off and begins working again

ive never had a fuel pump stop and work again, usually they just go and never work again.

if it was a fuel pump problem wouldnt it affect the driving?

not everyone wants to shell out 65 dollars an hour to get there car fixed if they might be able to do it themselves...

only way to know for sure if check for voltage at the pump when its acting up and wont start, if it has power its the pump. if not its a relay of the ecu or a sensor.

i have, especially if i got under the vehicle and banged on the fuel tank a couple times :D

i doubt its the fuel pump if you can hear it turn on every time you turn the ignition on.

He may not have been referring to how hot the engine is, but how hot the fuel pump is. Gasoline acts as a coolant for the fuel pump itself. If you run your gas tank on E all the time, or it is malfunctioning then the correct amount of gas might not be running through the pump and therefore the pump might be getting hot.

right. could it be ignition coils or wires getting bad? it is getting spark though

anyway to chk the fuel pump? their is gas in the car though about a quarter tank.

You never know...spray the wires down with wd40, see if that fixes it.

Or , start your car, and run it at night...youll see if your wires are bad, its like a lil lightning show just for you.

my old escort had bad wires and it would act up only once in awhile...

if you hear it running...it is most likely good. The right way to do it is to get a dmm and check the wires for the fuel pump for correct voltage..

btw, how many miles on her?

get the ****** diagnosed. Ovbiously he is not getting any help on a Car audio forum, anything anyone said on here I would take with a grain of salt.

If his check engine light is not on, he does not have any problems that anyone is talking about here besides a fuel pump. However, the fuel pump would not do as he is describing. the car does not shut off everytime it runs for a prolonged period of time (stalls on him) It just will not start if the car is warm. Take it to a garage for diagnosis.
