Hi, I have some questions I am hoping someone can offer insight on about my Jaguar. She is a 2000 XJ8L, and she sat for over a year. I was driving a 1999 XJ8L, and she ran like a charm, but was totaled recently in an accident. Here is where we will start.

The 2000 would not start....she did the whole turning over, but never kicked in. I then did the oil in the cylinders, and that seemed to help, in that she finally started but would cut off if I took my foot off the accelerator. To keep her running I would have to have the gas depressed about halfway. And it sounded awful and weak.

Showed Restricted Performance, etc. SO I ran the codes with my scanner, and came back with these:

P0305, P0306, P0307 and P0308. Coils bad or faulty Plugs.

P1314 - Misfire Rate Catalyst Damage Faulk Bank 2

P0327 - Knock Sensor 1 Circuit Low Bank 1
P0332 - Knock Sensor 2 Circuit Low Bank 2

P0352 - Ignition Coil B (Electrical Secondary) Primary Computer Circuit -same below, I have only added the Coil Letter.
P0353 - C
P0355 - E
P0358 - H

P1368 - Ignition Spare Ignition SYstem Failure Group 2 Passenger Side

So, I went out and took the parts off the 1999 Jaguar, that was running perfectly well up until the accident, and placed them in the 2000 Jaguar. My research led me to believe that the coil packs, knock sensors, etc., were interchangeable.I also installed new spark plugs.

Now, she won't kick in at all. She turns over, and will nit fire up at all.

I am at a loss at this point. I have put in clean fuel, added gas dry in case there was some excess moisture in the tank. All to no avail. I have checked the gas line via the Schrader Valve on the metal line, and it will squirt out fuel if I depress it after having placed the ignition in the on position. I cannot detect any vacuum lines not connected, etc.

After changing the parts, I cleared the faults and they did not return. However, the engine did not actually start. It was just turning over and failing to kick in. I also tried a bit of starter spray, but didn't want to put too much in as I had read some bad things potentially happening with that. Even then, still no luck.

I am hoping some members will reply with suggestions to help me resolve the issue.

Should I put the old coil packs & knock sensors back on....as at least it was firing up at that point? I should point out that I no longer show coil packs or knock sensor faults, but could that be due to the engine not actually running, as opposed to just trying to start?

Any help is GREATLY APPRECIATED.

I forgot to thank everyone ahead of time for reading my post and responding. Thank you for any help or insight you can offer.

Welcome.

I suggest a quickie repost in the X308 section for maximum reading by the people than will help, as not all members come in here.

One of the Mods will sort it eventually, when the time zones align a tad better.

Welcome aboard Mike.
