SOURCE: 1994 jaguar xjs just clicks when i try to start

If there is a power drain - new battery or old - it needs to be well charged to start the car..
If the batt is charged well - it could be the starter solinoid or the starter..
However - the typical "clicking sound" is usually a low battery..
IF the batt is low - could be the charging sytem or a power drain ..

I would start with a tune up, then isolate any symptoms other than lack of power if it persists, like rough idle, sputtering, jerking, engine trouble codes, etc.

I have a 2002 X-type Jag. My engine light comes on and I had it check. The code is P1796. Can you tell what this mean?


My records show that P1796 Fault indicates a Kick Down Switch Circuit Malfunction, however there appears to be some discrepency here as other records show it as a CAN bus (off) fault. A quick check to see if your car will go into kickdown should identify which is which. Clear the fault then drive gently for 20-30 miles, if no engine light then use the kickdown and see if it comes on. You can check out other fault codes at http://www.bluejag.co.uk.

Need radio code for 1993 xjs


the only way to retrieve this code is to call the dealer(they may have you come in) and prove ownership with registration and VIN and they will give you the radio code and process to reset. if you still have the owners manual, many people write the code somewhere in it just in case.
