I need to disable the fuel pump to perform a compression test, I've searched high and low for the location of the fuel pump relay, and can't find it anywhere. If anyone knows another way to disable the pump, I'd be interested to hear that too.
About 3 PSI less than at sea level.ON this topic, what should compression be at 7000 ft altitude on the BRM? I am getting ready to test one soon.
I would add, don't turn the key on because the engine will try start even with the in tank pump disabled.I just jump the crank wire at the starter. Easier anyway, since you are under the hood and it is right there.
