Wink Gentlemen: (No)Start Your Engines!!!

Seemed like every other day a new no-start thread would pop up...some days 2 or 3....so I thought I'd try to take the pain out of search for some of you:

By no means an exhaustive list - I quit after culling through the first 200 of 500 results; but this should get you started ...er so-to-speak

Good list.

I am amazed the mighty X300 is such a troublesome car, mines not.

Maybe its the maintenance, or lack of, OOPS.

OH.

I'll start.

ALL mine do, and always have, once my maintenance after purchase is completed, and that is usually within the first week.

The only mongrel was the X300 (BUGGA), which drove home fine, and 15 minutes later failed to start, so the XJ-S was the chariot of choice to take Madam for dinner. Turned out to be the Crank Angle Sensor, and smack on 160000kms (100000miles). Took all of 10 minutes to fix at about midnight, after dinner.

But why so many and all at the same time? I too was a victim just last Monday. This can't be a coincidence. Got mine back from my trusted Jag tech. Problems were, aftermarket coil packs, blown fuses and corroded ECM connector.

Well, the replacement coils do seem to be a recurring Achilles heel... so that pops up a lot.

Corroded ECU connectors do also seem to come up, and that begs the question is there any preventative maintenance (like opening up and using dielectric grease on seal) to help with this? BTW, where is it?

I just went out and started my 1997 XJ6L and it still ran fine.
I have 2 X308 sedans, 1 X300, several VWs and a Chevy Pick-up so I don't drive many of them often. (My 1986 Ford Diesel Tractor ALWAYS starts)

I seem to always need to replace dead batteries.

Just thought I would share some GOOD news instead of complaining about my cars that DON"T start.

The corroded ecu seems to be from water ingress. No grease is going to fix a connector that gets damp regularly- The sunroof drains have been blamed for the water problem, and considering the recent rash of reports, I wonder in an end of life event is occurring with them.

Welcome to the forum colin124. The battery or connections could also be at fault. Check the voltage both before and during cranking.

I have uploaded HUNDREDS of TSBs to the large file area.
There is a wealth of info.

Here is a TSB you need to read.

Hmmm....either the forum has changed and put a time-limit on posts for edit...or I've mistakenly thrown a switch somewhere...can't seem to edit the original post anymore...so here we go:

https://www.jaguarforums.com/forum/x...ession-125018/

Well, this explains it: https://www.jaguarforums.com/forum/j...t-post-124489/
There is a 30 min. time limit. Makes it impossible going forward to make useful compilations of similar-issues like in Post #1 above...but as Graham says, they have their good and proper reasons.

This one won't be much help to you, except perhaps to give you hope to go out there and reset everything and "give 'er one mo' try!"

copy URL and paste it in here! As I said in Post#1, the original list was what I culled out of the first 200 hits on a "start" search. (There were over 500) After that, when I'd see a new one pop up, I would edit it to the top of the original list. Then the mods came along and put a 30 min time-limit on edits so I couldn't do that anymore; Now I just plink 'em in here as a next post, so feel free to add.
