If you are using the old style trim pumps, (has the small black knurled filler plug on the side of the pump) this is a common fault.You will find the relief valves are bypassing. these pumps are supposedly non serviceable. The best option is to change to the later model pump. The later model has a white plastic reservoir on the bottom of the pump. At least with the later model pumps, you can buy service kits for them if needed.

Sounds like the trim switch is not holding the trim. Test the switch or change it if it is available. Check all the wires coming off the switch, test for shorts. Clean all the connections.

the docs got it right. if it's not simply the bypass valve being open, the best bet is to replace both units. there are excellent after markets to be had from ARCO, Sierra, and others.
