I took my car out of storage today…

I decided to attempt to disable the fuel pump to move some oil around and build some oil pressure ahead of doing the actual start. I know there a competing ideas on the forum here around whether this is worth doing. My car sits for 6 months at a time so, wrong or right, I made the decision to do it…

In any case, much to my surprise the car unexpectedly started up immediately despite my having for sure pulled the fuse for the fuel pump. On the 2024 it is fuse 18 in the bank of fuses in the trunk area. I confirmed it in my manual before doing it.

I was so sure it would work that I hadn’t even opened my garage door at that point ;-0 lol

A local Jaguar specialist a few days ago told me that they pull the relay for the fuel pump to achieve the same thing that I was try to do when they do work that might create a “dry engine” etc…I suppose I could try the relay instead next time (wherever the relay might be located).

Most of the generic advice for this sort of thing out there always seems to suggest achieving it by pulling the fuel pump fuse.

Regardless, anyone have any thoughts around why the car was still able to start with the fuse for the fuel pump pulled?

 

Isn't there 2 fuses, one for high pressure and one for low pressure pumps?

 

Hmmm…

I looked at all fuse descriptions in the various tables in the relevant section of the manual and it only showed 1 fuse for my 2024 at least.

Perhaps it’s different on some or all of the previous gen f-types?
