Ran fine when put into storage. Installed new battery, now cranks but won't fire. Tried moving (switching) the fuel pump relay #6 with the rear defroster relay #2 and no difference. Checked for voltage at fuse #7 (20 amp) but show no voltage on either side of that fuse.

Any ideas?

 

Fuse 7 mentioned above was something someone said to check, I don't even know if it's related to fuel system.

Also online someone said battery must be at least 850 cold cranking amps or these XJ8's won't start! Any truth to that? One I bought is only 825 CCA.

Last there is supposed to be a fuel inertia switch that I can reset...but I can't locate it.

Thanks!

 

No the small CCA difference will not matter.

There is a schrader valve on the fuel rail. Check for a strong squirt of fuel when you depress it after cranking. It is quite common on these cars for the fuel pump to fail after storage.

Also, post next time in the X308 group, this is the group for later model XJs.
