What up to all I am the proud owner of a 2000 xj8 4.0 litre with over 200k . I've had the car for about 2yrs never had major issues only problems with u joints I believe that occurred due to 22in rims but anyways this past month the car started stalling out on me at first it would start right back up then I ended up getting a tow home . I purchased a scanner and pulled codes for crank sensors and knock sensors so I replaced them along with plugs the car started and seemed to run fine but after about 25 mins it stalled out again I rememberrd reading a thread that said the throttle needs to be cleaned so I did car started and was fine for about a week . On my way to work I saw restricted performance the car started hesitanting and then stalled out I restarted drove a few blocks it did the same thing this time it never started again . I get towed home . Put the scanner on it this time I got 11 codes p1111 p1367 p1368 p1000 po351 thru po358 . I looked up the codes I could find and its basically giving all the coils . I find it unlikely that all would go at the same time has to be something powering them I just don't know what please help me thanks in advance

 

What's up all I'm really trying to get my car started I've posted but don't seem to be getting replies I've read threads and tried some of the suggestions that seemed to work for others come on guys please help me out as I need really badly to get car going thanks for any help

 

Are you seeing any oil leaks from the valve cover gaskets? At 200k miles, if they haven't been replaced, it's almost guaranteed that some oil got into spark plug wells, and is impeding the coil packs from properly sending "jolt" to the spark plugs... Quick way to check is take the valve cover off (either side), and remove them coil pack thats closest to the cabin (first to fill up). If you see oil in the spark plug well, clean it out. Repeat for all others... Eventually may wanna replace the gasket... ~$75 a set... 2hrs max...

 

Well, 1367 and 1368 are 'Ignition System Monitor failure group 1' and group 2... so it's something before the coils.

Possible causes:


Ignition coil relay failure


From these causes, I'd look for a common connection between all coils that is loose, dirty or intermittent. For instance, all 8 coils share a common ground point - according to the electrical diagram, the black wires from the coils all tie to common junction (called PIS13) and a common connector pin (PI1, pin 55). They also share a common supply thru junction PIS5 and connector PI1, pin 53... so I'd first find and look at connector PI1 (back, right side of engine near firewall), pins 53 and 55 to see if anything is obvious. Electrical diagram says it's location is: ENGINE COMPARTMENT / BULKHEAD / REAR OF ENGINE


Of course, the Ignition Coil Relay is shared by all, so this could be the problem.

Honestly, I'm surprised someone with more knowledge than me hasn't chimed in within the last 7 days, so lets keep giving this one a bump until someone does.

 

Thanks for the reply I m going to try the relay and then go from there I did notice some oil in the spark plug wells but it started and ran for a week , I assumed it was from adding oil to the cylinders but I'm going to look into it too

 

Quick question can anyone tell me where are the ignition relays located I got a down loaded manual not really giving me exact location almost seem like its more then one

 

This oneline for the car should help you with finding the relays http://www.gusglikas.com/images/Auto.../jagxj2000.pdf I am also attaching a Summary of the OBD codes that should help. http://www.gusglikas.com/images/Auto...J27%201999.pdf I hope this helps!

 

Relay location is shown on page 35 of the electrical diagram that Gus linked for you - assuming LHD vehicle, rear of engine compartment, right hand side - with several other relays, 4th in from center of engine compartment.

 

Just wanted to thank you guys for all your imput and links to useful diagrams , had it not been for you guys I probably would not have been able to get my car started. It ended up being the relay to the ignition coils as soon as I put it in car started right up. Although I'm getting misfire on cylinder 5 . Figure ill drive it a few days and see if it changes if not ill be replacing plugs and or coils

 

which relay was it?

 

 

Wow: resurrection on a 11 year post . . . .
