Nissan clutch cylinder

OK. Just replaced the clutch master cylinder on 93 Nissan P/U. 4 cylinder, 2-wheel drive. Bolted to firewall, link to pedal secure and brakeline tight. pour in brake fluid and pump the pedal sloowly.

Problem; no resistance or return of pedal (stays at floor).

Do I need to prime the master cylinder? If so, how???
Got Momma helping (and we done had the big fight over "move it that way") so I'm ready to work.
Thanks in advance for advice.

Should be no bleeding of the master required, but you will need to bleed out the air elsewhere in the system.
Locate the slave cylinder and find the bleeder. Push clutch pedal to floor and open bleeder. Close bleeder and pump clutch again and hold at floorboard. Open bleeder and close again.
Repeat until all air is expelled.

Also, hydraulic slave cylinders frequently fail more often than the master, so make sure the slave is not leaking. For a '93 vehicle it may be wise to go ahead and change the slave if it is original; it will fail sooner or later.
