Replaced Ignition Coils - No start

Replaced Ignition Coils - No start
I developed a misfire a couple weeks ago so I bought a full set of ignition coils for my '96 XJ6 from Japthug on the forum here.
I replaced all of the coils today along with the spark plugs. The plugs are Champion RC12YC as RC12YCC is no longer available. The gap is .035"
I went to start the car but all it will do now is crank. No starting at all.
I made sure the best that I could that all of the coils are seated correctly. I disconnected the battery for about 10 mins to reset everything. Still nothing.
I'm stumped.
Anyone have any ideas?

I also replaced all coils (96 VDP) with the same, back in the summer ..like you, I thought I had properly seated them all. However, it started very hard and ran badly. I then removed them all and sprayed silicone around the boot tips and reinstalled. Started instantly and ran smoothly.
Worth a try? Just don't use the evil WDxx....rots the rubber!

Uh-oh....Jaguar's sense of humour again ....the coil fuse (same number ) is in the RH Engine Bay fusebox....
Which of course is much more logical ....but the Jaguar Manual Power distribution wiring shows the fuse at both the Heelboard and the Engine Bay....
Which proves that when all else fails, ignore the instructions ....:-(

First you will have to check if the coils spark.
You could pull off the No.1 coil about 5-10mm and have someone crank. If the system works right you can hear the coil sparks (clanging noise)
Or you can pull of the coil, remove the coil boot and let the terminal be close to the body ground and have someone crank. In that case you can visibly see the spark.
If it doesn't spark, it will be either a ignition coil relay, ignition positive relay, or a crank sensor.
