Could just be a vacuum leak or the throttle plates are dirty

My xj8 Jaguar crank up and sets right back off what all could be wrong


Security is set. Could be one problem. Fuel system can do this, but rarely. Takes a scanner to see where to look first.

Hit pothole real bad no damage to car checked all fuses battery it's self has spark but car is unresponsive when I try to turn it on what do I do now jaguar xk8 convertible 1998


In the 1999 Jaguar xj8 there is a fuel cutoff switch on the passenger side right hand panel to the right of the feet. Reach over the top rear of the small panel and find a soft flexible membrane on the top of the switch and press it until it clicks.if that doesnt work,there is a fuel pump relay in the trunk fusebox that might be the problem. 1998 Jaguar XK8 fuel safety shutoff Bing images

What causes my 1998 Jaguar XK8 not to start when initially cranked and the Fail Safe message is displayed?


Is the check engine light displayed? If it is, that's where you start, by retrieving the fault code(s). If not, then you could have a security system fault, fuel system breakdown, etc. All codes, regardless of the systems affected, will cause the vehicle computer to immediately default to a failsafe mode, till the problem has been fixed, and this drastically affects driveability, causing no-start issues, idle problems, etc.

Luggage LIghts do not light up when opening trunk


The Microswitch is actually attached to the Latch mechanism But I would suggest that you mark the position of the latch BEFORE removing the bolts as there is quite a range of adjustment available when the bolts are loosened!

Failsafe engine mode light comes on, codes


Just a quick mention - for about a month my XK8 low coolant light came on intermittently. This week with no notice while driving normally I got Stability Control Fail and FailSafe Engine Mode and wtih great difficulty got the car back to where I started from (less than a mile). Two days later (when got time) and after a bit of research, I tried it again - same problem and a very unhappy engine. I then disconnected the battery for 15 minutes (probably more) to clear the engine codes as well as check all the wiring and vacuum stuff I could under the hood (at a Jaguar master mechanic's recommendation). No problems found but the car would start and immediately stall with the air intake hose disconnected from the intake butterfly. After I reconnected the air intake hose, she started and purred like normal. The problem is the BATTERY... It is low - I've known it for a LONG time BUT it always started right up and never skipped a beat. I intend to replace it tonight but fully expect that's the issue. I've had the car 6 years (it's a 98) and had NO problems except a dead taillight asembly.

Hope this is of value...

Headlights & tail lights are not working suddenly check fuses


Have you checked the relays?
Even if a fuse is good, a failed relay will prevent power from reaching the lights.

Compare what you've checked with this photo of the fusebox assembly, just to make sure.
