The problem is the engine struggles to start but does always start. On starting it either goes into idle and the accelerator will not make any difference to the idle speed or it kind of runs ok but misfires and runs rough. Limp mode comes on almost immediately at start and P0336. If the reluctor and...

I have a P0336 which I know is not due to the sensor or wiring harness. The wave form show 35 voltage peaks and troughs going from plus 2.37V to -2.46 volts. The last three notches create roughly a 10% increase compared to the others. Does this signify a correctly operating crank sensor on a correct...

Battery is new and fully charged.

I have an XK8 1999 with the following IDS codes Engine control - P0336, P1646 Instrument pack U1260, U1261 Transmission control P1798 Climate control - request cannot be processed due to a bad specification or missing parameters Restraint control module - communication with module has been lost. I a...

I now have IDS and the codes are numerous including Anti lock braking C1155 and C1233 Restrain control module - No communication A load of climate control ones Engine control P1260 - I think this one is significant but do not really know how to further on this diagnosis Instrument pack - U1260, U126...

I have disconnected the chirp sounder in the Drivers wheel arch. Will check relays, fuses and grounds again. Cheap code reader brings up no codes. I am purchasing IDS and a mongoose so will see over the weekend. 2 Questions 1)Can a Jag dealer read a damaged key and clone it to a new one ? If the key...

Yes I have done the reset.

How do I find out the code on the key ?

Thanks

Thanks a lot for the investigation and you were right the earth was very rusty. However I am afraid the symptoms still persist.

Any more thoughts ?

Thanks

Afraid not. I have tried resetting that.

Thanks

More info. The battery is brand new and fully charged. According to PO this key used to work. Not sure how I verify that. When put in the ignition the dash lights come on and noises happen in the engine area but will not crank. No DTC codes on basic scanner. Symptoms Door lock unlock does not trigge...

I recently bought a 1996 xk8 which the previous owner told me had suddenly stopped cranking and the alarm was going off. I only have one key and no fobs. Having now got it the symptoms are On unlocking the car with the key the Alarm goes off and doesn’t stop if the key is inserted into the ignition ...

Thanks for the replies. I have moved on a little. I had a blown fuse on the coils which takes me back to where I was when I bought the car in that it will start but often takes multiple attempts to get it going. Once going it runs unstable and putting any foot on the accelerator causes it to falter ...

Should I buy a mongoose cable and IDS v130 to get the crucial data ? Would icarsoft be as good ?

Thanks

Thanks Mike Yes the engine ran on both ECUs the same but it was difficult to start and it would not tolerate much throttle. It got harder and harder to start then stopped completely. The only difference the new ECU is as that it didn’t have as many fault codes on it. Before I splash out someone sugg...
