Hello there

I am in the process of ordering one relay (LNA6706AA) for the ECM of my 1995 XJ6.

Please recommend a list of other relays which I should order for future use on my car.

Thank you.

Jack

 

Hi Jack,

Is the relay you need to replace the "ECM-controlled relay" that powers the fuel injectors and is mounted near the upper right corner of the radiator in a group of three relays?

The other relay in that general area that comes into question from time to time is the ignition coil relay, which is in the same general area of the engine bay but mounted on the right front inner wheel well on the left end of a group of three relays. I don't know how often the relay actually fails, though, as the coils themselves tend to be the more common failure point.

To identify the relays in your car, see the diagram in the 1995 X300 Electrical Guide, which you can download at the link below. The diagram of relays is on page 26 of the pdf file:

Cheers,

I have driven two X-300s a total of 250,000 + miles abnd have NEVER had a failed relay. Yes, they fail, but I doubt having spare relays is any better than havingspare belts, hoses, fuel pumps, dampers, and lambda sensors which fail at least as often, if not more.
Just sayin...

 

Thank you, Don, for your quick response, and for the diagram. Yes, that is the exact relay that I will be replacing.

Now that you mentioned it, I will be ordering for the ignition coil relay too.

With much appreciation

Jack

 

Not sure a stash of relays is really required, but the relay you mention is only $8.50 on the everydayxj website right now. I don't know what shipping would be, but I bought that relay from an indy shop for $19 about 2 years ago.

 

Thank you Joe for alerting me of the relay from everydayxj.com

Based on what sparkenzap said in Post #3, I am beginning to question the wisdom of pre-ordering parts before the problem occurs.

 

Well, on the other hand, I have to admit that I have a spare X-300 engine long after my X-300s are gone! It sure seems that if you have a spare, you never need it.

 

I can beat one measly spare engine. I had 3 and a half Rover V8 engines after I sold my Range Rover and a gear box Sadly all worthless.

 

So...after reading what Posts 7 & 8 had held for spares, I think keeping one spare relay, or two, is quite affordable!

 

heh, heh. Although I was lucky and never needed one, a CKPS seems like it would be good to have around- It is not as easily bypassed or substituted like a relay.

 

While we're on the topic of spares, I think it depends on how you are using your Jag. If you're strictly driving it around town within easy access of a tow home, should your kitty suddenly decide to stop running, you don't need to carry many spares. Back when I was driving our '93 daily to work, the only spares I carried were a CKPS and a small tool kit (and the spare fuses stored in each fuse box).

By the time our son began driving the car to and from college 6 hours away, I had put together a kit of spares to cover most sudden no-start and potential safety issues and a few other bits I had collected:

Along with jumper cables, a small tool kit, and a roll of duct tape, he was covered for most common causes of roadside breakdown.

+1 on the duct tape!

 

I have a question on the Coil relay. I drove my car to my house and the next day or two it would not start (it was running rough previously). I took it to my mechanic, the relay was missing, he used the window washer relay and the car started. The Coil relay was marked lna6710AA. That was just the casing with no relay inside. So, I ordered the lna6706aa and it works.

The question(s): would the car start without the relay? Why the two part numbers? Did somebody steal it? Did my mechanic misplace it or replace it?

 

I'm pretty sure the car won't start without that relay! The two part numbers happen because the shell relay is only a cover... no one stole it. It is for the headlamp powerwash system which is not installed on USA cars. It is possible the locations of the 3 relays in that row were changed around in the past, leading to confusion as to which is which. It is possible that the relay was not making good contact. When the mechanic removed and reseated it or swapped it, then all was well.

You would be able to tell which relay is which according to the wire colors found on the socket it plugs into. They are reliable devices, but poor contact can happen after 25 years.
