Aircraft
Upon climb out we had a pressurization problem. At approximately four to five thousand feet we noticed the cabin climbing at the same rate as the aircraft. About the same time we got an AUTO FAIL light. We asked ATC to level off at 8;000 FT. The Outflow Valve indicator was at full closed. We ran the QRH and manually DC toggled the outflow valve to full closed but there was no change. Contacted Maintenance Control and after talking to them we were over half way to our destination so they elected to have us continue. When we were 10 miles from the outer marker we received a SELCAL message saying the company wanted a phone patch but we had no time. Upon landing Tower informed us the company wanted us to go to a different airport.
When the B737-400 flight crew was unable to pressurize the aircraft during climbout they elected to continue their flight to destination at 8;000 MSL as they attempted; unsuccessfully; to trouble shoot the problem.
