2003 x type jag will not start

SOLUTION for x-type Transmission fault error
I had this very same problem. My 02 x-type would get transmission fault code and then shut down into limp mode. If I turned the key off, shifted gears a few times and waited I could start up again and sometimes drive for several miles before the code came back. GOOD NEWS, I thought maybe the vechicle was overheating the tranny or something like that and then after it cooled down I could drive some more. I discovered that my gas station had switched to the 10% ethanol addative about the same time I started experiencing "strange" mechanical issues. I decided to try switching my gas to the non-ethanol gas from a Phillips 66 station that advertised 100% REAL GAS. The problems mysteriously dissappeared!!!! Remember that you MUST use PREIUM gas as per the MFR. Well the 02 3.0 can't handle the 10%ethenol in it's gas. Something else you can try if you can't find REAL GAS is to use the OCTANE boost from your local auto parts store. Pay close attention to which brand you buy since some can harm your fule system. As a side note; I also own an 04 s-type with a 3.0 under the hood. It looks different from my 3.0 and has no problem running on the ethenol added gasoline. However after the horrible mechanical experience I had with the ethenol in the x-type, I now use 100% real gas in both. I have been transmission fault free for 5 months now.

You likely have one of two issues.Assuming it is not a security feature such as a coded key causing the issue.

1. the trigger wire isn't getting the 12volts it needs to turn the starter every time you turn the key. If that's it you have an electrical issue some where between the ignition switch and the starter.it could be a corroded wire connection or a bad contact in the switch among other things that would facilitate a bad connection.

2. Starters almost always do this when they're ready to quit for good. The contacts in the starter itself are likely worn and you aren't getting a good connection every time you turn the key but with repeated key turning you are heating up the bad connection and it will then conduct the voltage that it needs to function.

Number 2 is the most likely and the least expensive one to try, as electrical trouble shooting is time consuming and if you are paying a shop to repair it they may spend hours looking and still not find the issue

Hope this helps and thanks for choosing FIX YA!

Check your brake fluid level first. If it is fine then you probably have a bad abs brake sensor.

Hi there:
You will have to pinpoint what the engine is missing... spark / fuel / compression.

All three of these are tested when the engine is being cranked over. There are two way of checking for fuel. Fuel pressure and fuel trigger. Both are very important and must be present for the engine to start. Fuel pressure is self explanatory. You just hook up the gage and see what the reading is. Fuel trigger is check with a noid light. The injector gets unplugged and the noid light gets plugged in to the injector clip. With the engine cranking over, this light must blink. This is the signal to the injectors from the computer. You can have all the fuel pressure in the world, but it wont matter if the injector is not pulsing gas into the cylinder like it should.

Compression tester, spark tester, fuel pressure gage and noid light are all accessible at your local auto store. All three tests play a very important part in diagnosing a no start condition. Be extremely careful when doing these tests.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.
