engine coolent temperature sensor is giving incorrect readings when warm
when the engine is hot the check engine light came on and the fan(is ok) don't start
It could be down to your Canshaft sensor, Which will start when cold and Hot but when you have run for a short time (3 or 4 minutes) Look on this site its very helpful :- http://forums.mg-rover.org/index.php cheers Carl
There is a large screw which goes through the coil pack into the engine block. That screw will get to hot and then cause the engine to stop or not start back when it's hot.
the two most common no start when hot causes are fuel pump in your fuel tank and loss of spark ignition module
Battery is probly good. If it was bad there would usually be a series of clicks while trying to start. If the engine is is too hot then the computer is not gonna let the vehicle start. If it is not over heating then the coolant temp sensor is probably failing. This is what tells the engine what the the coolant temp is in the engine. Hope this helps some. Of course there are always other factors such as the engine is over heating the starter causing it not to start. Stuff like that. Impossible to say for sure. Just gicing you some things to check. Good luck.
A hard start when the engine is hot but a good start when cold can be attributed to several factors. One common issue is vapor lock, where fuel vaporizes in the fuel lines, making it difficult for the engine to start. Additionally, problems with the ignition system, such as faulty spark plugs or ignition coils, can also cause difficulty when the engine is hot. Checking the fuel system and ignition components can help diagnose and resolve the issue.
it should start at cold
Yes the reason for that is because the engine is over heated and when its cold the engine is nice and cold perfect for starting conditions.
To check the transmission fluid level on a 2001 Land Rover Discovery, start with the vehicle on a level surface and the engine running. Locate the transmission dipstick, which is usually found near the rear of the engine bay, and remove it to wipe it clean. Reinsert the dipstick fully, then remove it again to check the fluid level, which should be between the "hot" marks if the engine is warm. If the fluid is low, add the appropriate type of transmission fluid through the dipstick tube.
Because the engine gets too hot. Let it cool down before you start it up again. Poor water on it.
It is bleeding down---- Leaking fuel out of the fuel bowl and flooding the engine. In other words fowling the spark plugs out. When a engine is cold it needs more fuel to start. But when a engine is hot it needs less fuel to start. You need to make sure the choke plate is opening all the way up when engine is hot and it should stay open until engine cools off. If it is closed when engine is hot that will also flood the engine and it will not start. If choke is working then REBUILD carburetor.
If there is no check engine light illuminated, start with the basics like a good tune up.
