![Question](https://www.jaguarforums.com/forum/images/icons/icon5.gif)
I own a 2004 Jag S Type v6 3.0 - I was driving Fri night and all the sudden my car acted like it was out gas and it wouldn't start again - let rest it started right up but soon as the engine got warm it shut down again (I had electrical power) so I was told it could be the crankshaft positioning sensor so I changed it, car started right up but again it stalled again once it got to running temp and wouldn't start back up - can anyone help me pleae

sounds more like a fuel pump issue to me -- I didn't know a fuel pump could act that way, I assumed when it goes bad it just would let you car start at all, have you heard this happen before?
You can watch fuel pressure via OBD2 -- could you please expain how to do that, I've never done that before and what is OBD2?
thanks for the help

OBD2 is the second SAE version of OBD (on board diagnostics) , there is a plug just to the side below the steering column .
you need a scanner or an obd2 dongle compatible with your smart phone .
blue tooth for android ,
and wifi for Apple iphone / ipad .
then you just need an app loaded on your phone so you can see what the car is telling you.
such as torque app or OBD car doctor or dash command .
you should always check this first before purchasing parts as you just learned .

jagstytpe2004, here is a range of OBD2 scanners from site members:
https://www.jaguarforums.com/forum/g...-%2A%2A-33347/
I paid about £5 on eBay uk for a decent scanner and the software to view the codes etc on my smart phone.
Software came on a mini disc with the scanner.
The scanner will tell you where the fault is.
If you find the car needs a new fuel pump, then I suggest changing the fuel filter at the same time.

Good morning - thanks for your help - I do have this scanner, is this what your writing me about?
The Performance Tool Diagnostic Scan Tool works with most 1996 and later models, including American, European and Asian vehicles.
* Supports all OBDII protocols including the newer (CAN) Controller Area Network
* Reads your (DTC) Diagnostic Trouble Codes for identification
* Turns off check engine light (MIL)
* Erases (DTC) trouble codes and resets the OBDII system
* Includes an user manual with the most current trouble codes

I doubt that is the cause of your stalling problem.
P1111 is a common one, and I think it's saying the car hasn't been driven long enough for certain systems to complete their self-tests. It's not really a fault per se, it's just a reminder that not everything has been tested yet.
P0442 is a minor leak sensed in the fuel tank's evaporative emission system. Also not a big deal, could be as simple as a loose gas cap. Even if the system has a vacuum leak big enough to affect the air/fuel ratio, the computer can adjust for it, and possibly set some other codes. The lack of other codes is a big clue that the cause of the stalling problem probably lies elsewhere.
Keep in mind codes are primarily generated for emission-related faults. A stalling condition typically doesn't set any codes because it's not an emissions problem. You gotta think like a bureaucrat sometimes when dealing with computers. Normal logic is not part of the equation...
You're in a bit of a pickle for effective troubleshooting. If the car had run poorly before stalling, that would have also affected emissions and hopefully set some codes to help guide you. Instead the engine just died. The computer probably knows why, but it wasn't programmed to tell you. It's as frustrating as waiting in the wrong line at the DMV.
What's a poor guy to do? Can you duplicate the problem in your driveway? Or does it only happen while moving? Once it stalls, will it restart right away or does the engine have to sit a while?
If repeatable, run some basic troubleshooting. Hook up a mechanical gauge and observe the fuel pressure as the engine starts to die. It's not a slam dunk if the pressure drops. It could be the fuel pump itself faltering. Or the pump may be fine but has been commanded off for reasons unknown. Or there could be a fault in the control circuit to the pump. Some sleuthing will be in order.
If the fuel pressure is within specs, I'd consider the crankshaft position sensor (CKP). When these fail, they don't always set a fault code. I don't like just throwing parts at a problem, but if normal troubleshooting doesn't find anything else, a CKP sensor is a reasonable gamble.

wow - we did replace the crankshaft position sensor (CKP) yesterday and unfortunately it's wasn't the problem - but I now have a new CKP - I will be installing a new Fuel Pump tomorrow and if that doesn't fix it I'm gonna call Jaguar and tel them there car drives me nuts
Oops, I missed your earlier mention of a new CKP sensor.
If you take the car to a shop, you may want to consider an independent Jaguar specialist instead of the dealer. Typically more experienced with older models like our S-types, and less expensive, too.
