Will not restart


Sounds like vapor lock. This is when the fuel turns into a vapor before reaching the engine (it needs to be in a liquid form). This is usually due to high temperature from the engine and environment. I would have someone check it out.

Will start over and over while still warm. when it sits for a few hours, it just turns over and doesn't start for about 20 trys.


The times when it does not want to start....is the check engine light coming on, in the dash? If it does not light up when the jeep refuses to start then your jeep ecu is probably in need of repair. Your ecu may be suffering from the 'delayed start check engine light problem.' Check to see, next time it doesn't want to start.

I have a 1994 Jeep wrangler. Once you drive it and it gets warm if you turn it off it will not start back up. Coil is good and we have spark. It acts like it isn't getting fuel at that point.


When it refuses to start, does the check engine light on your dash light up when you turn on the ignition, before trying to crank the engine? Does the fuel pump come on for a second, and prime the fuel lines, right when you turn the ignition on? Does the fuel injector wires get the pulse signal from the ecu while cranking when it does not want to start? If not, your jeep ecu might be in need of repair. It's a common problem with that generation of jeeps.

Sounds like you are right on the apex seals. Oil coming from the intake is probably from excessive blowby pressure in the engine due to bad seals. The battery could be bad from age, is it the original battery?

2.0d x-type 2005 Est. Starting problems when engine is warm


Ok, time for car school. The vehicle is operated by the computer, every electrical concept that is. When the engine is cold, it starts fine because the computer has placed it in "cold start mode", putting more fuel into the engine than normally would until Once the engine is warmed up, a temperature sending unit or temp sensor tells the computer to change to normal run mode. IF said temp sensor is faulty and is not telling the computer to make said change, it stays in cold start mode, still dumping excess fuel in the engine that is now not required, cause it's warmed up. Like keeping the choke closed on older vehicles. Now I think you can answer your own question, when this no start action is happening after warm up and it always starts fine when cold, what's the first thing you check ? Right, the unsuspected temp sensor. Change that and no more start problem. Have a wonderful day. Glad I could be of service.

2000 ford super duty 7.3 diesel will not cold start


you need to have the engine coolant switch checked,since the computer relies solely on sensors,the ect tells the computer how cold or hot it is so the computer will make it a rich or lean mixture to start the engine,if it tells the computer that it is 75 degrees the computer will lean the mixture like starting a car in the winter without a choke.
