Question about 2008 Land Rover Range Rover

Will not start on hot day's in the sun.[engine cranks normal]

Cranks normal but doesnot start.Mostly on hot days. Car starts but if you stop and turn off ignition, I will not start again. Is this a computer problem and or related to vapor lock? It happens in hot weather.
How do I correct this. Two dealers have failed. Still under warrenty.

    Thanks Robin:



    Your possible solution makes a lot of sense and I'll pass it on to the third dealer trying to fix the problem. Have the 2008 models needed updates to their existing computer software?



    Thanks for your time!

The normal reason why a hot engine doesn't start is the choke. Your fancy new range rover will have a computer controlled choke that will be activiated by a temperature sensor. maybe this has failed or is disconnected
In my ancient range rover I have a manual choke but essentially the same engine. I know that if the motor is hot I can't start it with the choke on.
The way the choke works is it restricts the airflow into the engine so that there is a richer fuel / air mixture which is needed for a cold start. If the engine is hot and the choke comes on the engiine floods with petrol and there isn't enough oxygen for it too ignite in the cylinders. To start a flooded engine you have to open the choke and crank the motor without pressing the accelerator. This pumps out the petrol vapour and eventually it will fire and start. If the computer thinks it is cold because of a disconnected or faulty sensor it will put on the choke whenever you try and start and the engine will flood.
I think a vapour lock is unlikely unless you driving in extremely hot weather (above 40 degrees celsius).

1) see the diagram

3) reset the igntion timing, it doesnot matter if your system ha BCM, adjust to accoridng the specification manaufacturer, because the BCM runt according to the information recorderd. remember the BCM =CPU.
4) test the sensor cam/crank with VOM see the diagram.
5) the head gasket i blown, valve timing is incorrectly set. the exhaust system is blocked.

Car starts fine sometimes, runs great. Other times it turns over good but doesn't want to start. Almost sounds like it is flooded.


Hi there,

Honda has a problem in hot weather... If you car has been setting in the sun.... Especially a black car... .and it fails to start..... Cranks over but will not start.... Open the hood and let it sit for about 5 minutes and then try to restart it...... If it works you know that the problem occurs from an over temp in probably the ignition module..... There is also a module on the car that is refered to as the MAIN Power Module... This module has been known to have bad soldering points. If your problem is only related to starting it could be the Main Module.

Hope this helps...........
thanx for using Fixya
have a good day
bye
take care...

1997 HONDA ACCORD WOULD START


May be, Your coolant machine is working too hard.. Because when hot/summer day , if my machine in long journey , and you resting your car , the fan sound is still on although you turn off your machine.. It's means, the coolant machine , or your engine component must be changed... I hope so.
