Hello folks. I am getting an FF36 fault on my '92 XJS V12. In looking at the injectors I noticed that the retaining clips for several of the electrical connectors are missing. I suspect that may be the problem (I've already cleaned the o2 sensor with no luck). I can't seem to find a source for these clips. Any suggestions?

I've attached 2 photos for reference. The first is a connector with the retainer clip. The second is a connector without the retainer clip.

 

They are on ebay, search fuel injector clips.

Jim, those do not appear to be the right clips. The clips you have pictured are for the quick disconnect version of Bosch EV1, I think FarmerPete needs the snap off style (or whatever it is called that Jaguar used. I wish they used the quick disconnect style!)

The wire clips themselves are unlikely to be available alone, but you can buy pigtails, steal the clips off them, and throw the rest in a junk drawer. This is one example that is correct style: https://www.ebay.com/itm/26621628884...mis&media=COPY

 

Looking at your second photo more closely…. The plastic connector itself is missing its lower half, not just the wire clip. You do need to replace the entire pigtail. In that case you might as well upgrade to the quick disconnect version because you have to cut off the terminal and attach a new one!

Thanks very much for all of the input. I'll be replacing the pigtails shortly! Could the current state of my connectors be causing the check engine light? The car runs beautifully.
