What is the correct fuse to pull in order to disable the fuel injection on a 2007 TL when performing a compression test? I was just wondering, since on my wrx i had to remove the fuel pump relay before performing one.

 

Unplug each Injector? But yes a common fuse would probably be better if available. Or a common wiring harness that all the injectors use.

Underhood main fuses- check the listings- Fuel Pump
No fuel= no problem

The ignition is what I would be concerned with- not like you can ground a plug wire here.
Check for a main fuse for it too

 

keep the injectors plugged in and keep the car at WOT this will give the the most accurate reading.
if its just air in the cumbustion chamber there is nothing heavy to try and bust the seals, so a little gas, and the TB open to let escaping air out, will give you best results.
just remember to have all the plugs disconnected!!

 

with our hi energy COILS on the plugs- I think we need a real experts opine on this one
It cannot be a good safe idea to just unplug the coils like that- stopping th eoutput of spark seems reasonable
