Why does my XJS ignition system not work?
It might also struggle around the peak torque point. Although the V12 constant energy ignition module is fairly tolerant (it runs OK with the blanked second coil removed – albeit with a loss of spark energy) the ignition system will behave oddly if the coil is not the correct load match.
What kind of horsepower does a 1992 Jaguar XJS have?
We may earn money from the links on this page. And yet, we’d still choose the Jag. The 1992 Jaguar XJS came with an updated version of the company’s venerable 5.3-liter V12, with 263 horsepower, 288 lb-ft of torque, and fancy Lucas digital fuel-injection.
What kind of fuel system does Jaguar XJ’s V12 have?
Dear Jaguar lovers let’s move to the fuel system of XJ-S V12. Well, the analogue (3CU) system used prior to 1980 is basically a box of transistors and diodes; it works reliably enough and most problems are traceable to a perforated vacuum sensor or worn tracks in the throttle switch.
Where is the auxiliary coil in the XJ ignition system?
The auxiliary coil, located in front of the radiator, is not a spare or a backup; it is designed into the system for producing a good spark. If either coil goes bad, the performance will suffer. Since mid-1989, XJ-S’s have gone to a Marelli ignition system that also uses two coils.

What’s the 0-60 mph time of a 1992 XJS?
MotorWeek tested a 1992 XJS V12 convertible and recorded a 0-60 mph time of 9.0 seconds and a quarter-mile time of 16.8 seconds. Yeah, that’s rather slow by today’s standards. That gorgeous Jag would get smoked by a 2018 Chrysler Pacifica ( 7.8 seconds to 60) or Honda CR-V ( 7.6 seconds ).
What’s the acceleration of a 1992 XJS convertible?
Smooth motoring, but not what you’d call blistering acceleration. MotorWeek tested a 1992 XJS V12 convertible and recorded a 0-60 mph time of 9.0 seconds and a quarter-mile time of 16.8 seconds. Yeah, that’s rather slow by today’s standards.
What kind of car would beat a JAG?
Yeah, that’s rather slow by today’s standards. That gorgeous Jag would get smoked by a 2018 Chrysler Pacifica ( 7.8 seconds to 60) or Honda CR-V ( 7.6 seconds ). Even a lowly new Subaru Impreza ( 8.4 seconds) would beat it.
How many cylinders does a Jaguar V12 have?
The Jaguar V12 H.E. has 12 cylinders, turns at 6500 RPM, and has 11.5:1 compression, making it one of the biggest challenges for an ignition system in production automobiles. To cope with this, Jaguar has incorporated some sophisticated ignition technology.
What kind of coil does a Jaguar ignition system use?
HE SINGLE COIL REPLACEMENT Jaguar now recommends replacing both coils with a single “solid” (not oil filled) coil (#DAC 6093, Ducelier coil – 0.62 ohms primary) that fits in place of the main coil.
When did the XJ ignition system go to Marelli?
If either coil goes bad, the performance will suffer. Since mid-1989, XJ-S’s have gone to a Marelli ignition system that also uses two coils. However, these two coils are totally separate; each one fires only six cylinders. HE MAIN COIL REPLACEMENT
It might also struggle around the peak torque point. Although the V12 constant energy ignition module is fairly tolerant (it runs OK with the blanked second coil removed – albeit with a loss of spark energy) the ignition system will behave oddly if the coil is not the correct load match.
Why is ignition timing important on a Jaguar V12?
The correct timing is vital to a smooth running engine, however it’s even more important on the Jaguar V12. The wrong ignition timing can lead to overheating and to a damaged engine. Link to Patreon: https://www.patreon.com/livingwithacl… Follow on Instagram: https://www.instagram.com/living_with…
How to tune a Jaguar V12 Part 2?
