Hey everyone so I just bought my first jag and I made the mistake of starting and stopping it a couple of time, then I went to drive home and made it about 10 miles and the car began to overheat then as I was pulling over it stalled itself out im assuming so no more damage would happen but now the car will not start, it trys to turn over but im wondering if I am now in need of doing a cylinder wash? Or am I looking at a bigger issue? Any advice is appreciated thanks again.

 

Read your OBDII codes and then post them.

 

Overheating is bad news. Look up other threads for ideas - which will include failed thermostat, failed water pump, fan(s) and so on.

 

Welcome to the forum! Sorry about the problem.

Over heating does not seem associated with cylinder wash and if it started and headed home 10 miles that certainly is not cylinder wash.

Got codes? Check fuel pressure. There was an early years throttle body issue that involved shut down while driving. What model year is yours? Might be a good idea to put that in you signature line.

 

Hi stoiber1985,

Welcome to the Jaguar Forums. It's great to have you with us, but we're sorry that you're having trouble.

You've already received some good suggestions and questions - please let us know the answers.

Overheating is not normally associated with a no-start condition, so you may have more than one malfunction.

As to the overheating, the basics would include checking the coolant level, checking for any obvious signs of coolant leaks or collapsed hoses, and installing a new thermostat to rule it out as the source of your problem. If your water pump has a plastic impeller it is possible it has failed and pieces of the disintegrated impeller may be blocking coolant passages. If you can get the car started, you can also confirm that the electric cooling fans are running and use an infrared thermometer to get an idea of how the radiator is flowing.

Regarding the no-start condition, my first assumption would be low battery voltage while cranking. Jaguars need a very healthy battery, and if the voltage falls much below 11V while cranking, the Engine Control Module (ECM) will not trigger the ignition to fire. Have you tried boosting the car with another vehicle's battery connected via jumper cables? If the car will start that way, you probably need a new battery and may also need to have the operation of the charging system tested. Most chain auto parts stores will do a basic electrical system test for free.

Also, since we're a friendly group, please visit the New Member Area - Intro a MUST - Jaguar Forums - Jaguar Enthusiasts Forum and post an introduction so we can learn something about you and your Jag and give you a proper welcome.

Cheers,

Don

 

Check coolant level.
Check the oil dip stick. If you have water in the oil the level will be high and a very different look than plain oil.
Does it struggle turning over with a fully charged battery?
These would all be symptoms of a bad head gasket.
If you do get it started and it has lots of white smoke, the heads are likely cracked or the head gasket is bad.

 

What do you mean by it TRIES to turn over? To turn over normally means that the engine rotates, driven by the starter motor. So I interpret your description to mean that the engine does not rotate when you turn the key to start. Is this correct?

There is a world of difference, in diagnostic terms, between an engine that turns over but does not start, and one that does not do either. In the words of Yoda... Try? There is no try.

 

Will not start - engine will not rotate to initiate the engine running

Will not start - engine will rotate but does not run

Sorta necessary information.
