S-TYPE INTERMITTENT START UP ISSUES

2000 Jaguar XJS

I have a 2000 S-Type that, since late October, has exhibited erratic starting issues. Out of the blue and with no prior warning, the vehicle will not turn over, as follows:
1. Ignition to START - gauges activate and dash lights – ABS, seat belt, etc. Come on;
2. Ignition to ON - system shuts down as gauges and dash lights shut down and nothing happens; no cranking noise, nothing.
I have taken the car to the dealer four times for this issue and they have replaced 1. An ignition coil and the battery; 2. The starter; 3. The ignition module. Obviously, none of these repairs fixed the issue as the Jag is at the dealer, and has been for over a week, as I write this.

On all but the third occasion of this issue, I was able to start the Jag later and drive it to the dealer. On the third occasion of this issue, the car would not start for three days and had to be towed to the dealer. On the three occasions, I was able to drive it to the dealer after it had sat for from several hours to over night.

Usually, this issue returns approximately six weeks after the previous repair was effected; however, this last time, the car refused to start he day after the dealer returned it to me (about 37 hours after I picked it up).

According to the dealer, they have called the Jaguar Tech Hot-Line to no avail as Jag has no idea what is wrong.

The dealer, currently, cannot replicate the issue; so, no repairs have been tried.

Any ideas on how to permanently fix this issue are appreciated.

Have they checked the ignition switch? Those Jags had some issues with the computer as well, hit them up about it. It is in a really bad spot and had water contamination issues

I suggested that it might be the cpu, and even mentioned your comment regarding water damage, all to no good. They didn't even try to humor me by saying they would check it or that they had checked it and it was fine. The dealer, for some reason, does not want to deal with replacing the CPU.

I even mentioned that I once owned a 79 T-Bird that would shut-down, even at 75 mph, from time-to-time and that was the on-board computer. Ford had to replace it twice, but the second replacement solved the issue. As for the Jag, the dealer apparently does not want to go into replacing the computer. This story did not elicite a rise from them either.

As to the ignition switch, they replaced the entire ignition module (switch) just prior to the last incident.

I went and got the car on Tuesday because they had it 9 days and could not replicate the issue. So far, the car is starting as it should, but I have no faith that it will continue to do so.

Thanks for the info to date; any other suggestions are appreciated.

Ask for the Jaguar area reps phone number. Have a talk with him about the problems you are having with the service dept
