Will not start
I am beginning to wonder if these jaguars are just to complicated for me? I have a 1981 XJ6 and had the car idling while working on my 1966 Nova and then it just stopped. I tried to start it with no luck. I checked a spark plug and it was firing then I pulled one of the fuel rails to the injector and plenty of fuel. I have l ways thought f you have spark and fuel it would start. Any ideas for what to try next. I have plenty gas and the fuel pump must be working f there is fuel at the injector? Thanks....Jerry

Good that you have fuel *at* the injector, but is the injector itself working?
Do the injectors click when cranking the engine?
If not....
Check the white/black wire that run aft along the water rail from the coil "-" post.
Check the bundle of ground wires at the rear of the water rail.

Might actually be easier to unbolt and lift up the entire fuel rail

Hi, before you get deep into some serious diagnosis, I had an issue with my XJ6 series 3. Drove it all day, parked it for the night next morning, it would not start. Sound familiar? Well after long thought, I call a mechanic buddy of mine he came over, looked here and there, tinker, tinker. LOL... found a vacuum leak.. readjusted a hose and tighten a few clamps.. She fired up and has run ever since. Good luck

Well I finally got back today, I removed the first two injector nearest the firewall. As soon as I cranked it, it fire right up and ran good without those injectors. Both injectors were working As soon as I stopped it and replaced the injectors it is back to not starting. Any ideas. Thanks..... Jerry

Yeah, sure sounds like the fiddle factor in play in spades!!!
Way back when, I bought a really nice Ford F150 4x4. First Ford truck with EFI ! EfI new to me as well. Soon after I got it, it developed a stutter when driving. On/off like.
I applied the fiddle technique. Idling smoothly In my drive way. Aware of the fan, I began to wiggle wires. Yahoo, a black one in he front left of the engine bay, when wiggled induced the stutter!!!
Ground! It lead back to battery - ! A loose connector mid stream.
Fix. Cleaned and tightened. And belt and braces, a parallel black wire.
Ran like charm til I decided to clean the throttle plates. Very gunky.
Ford decided to insert sump fumes before the plates, as opposed to after. Lots of cab cleaner and a brush and I got them clean.
Oh, oh, now it will not run. Flooded in carb cleaner??? So, I came up with a "brilliant" idea. I used my shop vac on the intake with throttle wide open. It worked. Lucky me no flame up in the vac!!!
Hint; Opening and closing connectors can clean the corrosion enough to restore continuity.
Idea: Strobe the HT from coil to distributor and verify ignition.

OK I pulled all the wire from the water rail and there were a few nicks I repaired and check the grounds. Having the wire above the cam valve so nothing is touching tried to start it nothing. I removed the injector from cylinder 3 and 4 and it started fine ran a little rough and idled fast. I put one injector in and it till ran but when replaced the last injector it would kill it. I don't know but I see a vacuum fuel pressure regulator, is there a way it could be it? Is there a way to check it. I tried disconnecting the vacuum line and starting it but did not start. Any help would be appreciated, Thanks....Jerry
