Hear relay click but pump doesn't come on

Took relay out
tested at connector
GY-Y 12V ignition on
T-Y 12V
GY-R - only shows 5v with meter connected to pos of battery
Pk-LB - grounded

couldn't get pump to run jumping t-y and gy-r

It seems like I have to check the pump by wiring directly to it. but what is the best way to do that?

how do I check for a bad ground on the pump? where is it grounded?

since I can't get the pump to run by jumping two pins on the pump connector to the battery I have to replace the whole master cylinder? is that really the only thing left?

The pump motor was available seperately at one time, but I dont know if is obsolete or not these days.

Best way to check the motor is with a digital voltmeter using the ohms scale. It should have a low resistance reading. If it reads infinite, then the motor is burned out. I have one or two extra motors laying around somewhere. PM me if you need one.
