After replacing power supply #1 led comes on then goes off?

Mac was dead, replaced power supply and #1 led comes on when power is applied, but goes off immediately. No voltages are measured on the power supply output, but 120VAC is present on the input to the board.

Contact your vendor - seem's like the power supply is still faulty. If you've experience and tools you could test it.

Should only be attempted by those with experience working with a multimeter or voltmeter and LIVE equipment.
If you don't know how to use a meter to measure voltages then you should not proceed.

If testing shows the power supply is not the problem, you most likely have logic board problems.
