Think my oil pressure sending unit has gone on me. it's pinned at 5.4 bars when started. Tried getting the connector off today after an oil change to try to clean the connections between it, but couldn't get it off. Its a 99. I pulled the red locking clip out (only came out about 1/8-1/4 of an inch) and then tried to remove it but it still wouldn't come off.
What is the key to getting it off?
