1996 4.0L Air Pump Relay Question
On my 1996 XJS 4.0L the air pump does not shut off - even after the car is turned off (and warmed up). I pulled the fuse which obviously shuts the air pump off, but if I plug the fuse back in while the car is warm the pump begins to run. If I wait overnight and let it cool down I can reinsert the fuse and the pump does not operate until next start up.
I was thinking the relay might be bad so I checked the owners manual which indicates the air pump relay is on a bank of 6 relays under the hood (left side by fuse box) and the base is green in color (all the other 5 relays are indicated as blue). Issue is there are only 5 relays on the bank - not 6 as indicated - and all are blue. Before I go pulling each relay one at a time, I thought I'd ask if anyone knows where the air pump relay is located (if there even is one) or if there may be another issue I should be looking into.

This was quite helpful. i wound pulling each relay and it happened to be the one nearest the firewall which was the first I pulled - it's a blue hella. Stopped by the local dealer this AM to get the closed relay but not surprisingly it's not in stock and it will take a couple of days. Not surprisingly (again) there is an updated relay for replacement.
