If there is leakage, the meter's display will change when you touch the probes to the transistor's leads. If there is no leakage, there may be a blip on the display but it will go quickly back to whatever the meter reads when the probes are in contact with nothing but air.
Read the following page and test as shown in the FET section of the page.

0.4... is OK if the reverse is OL.
It's not possible to get 0.000 and 0.474 on a transistor between legs 2 and 3 with 1 and 3 shorted. Re-check Q410.
All should read OL on ohms and diode check between leg 1 and the other legs of any individual transistor (no jumper connected).

Although you should have infinite resistance there and this transistor may be defective, technically, I don't think that this would cause the problems you were having.
clip leads onto pins 1 and 2 and move the clips gently side to side. Do this without touching any metal on the leads/clips or on the transistor. Does the resistance ever change from OL?
Do this for all 4 FETs.
