Need help just fished building my motor and have low oil pressure.
Ran motor for 5 seconds and the oil light did not turn off. Ordered a oil pressure gauge installed at filter housing and getting 2-4 psi
Engine setup.

Acl race bearings .20 on mains and rods. Clearance is 00.15"
Manley h rods.
Wiseco 1400 HD 85.5mm
Still running balance shafts and oil jets.
New oil pump
272 cams
Dual valve springs and retainers.
Running 10w-30
Any advice will be appreciated.

Did you pack the oil pump with vaseline or grease when assembling the engine ?

5 seconds probably isnt enough time. I would let it idle longer. If its a fresh build it should have assembly lube so running dry wouldnt be a worry for me. If your extra worried pull timing belt off and prime oil pump with a drill or by a pressurized oil can and feed oil in through cylinder head turbo oil feedline.

Removed oil pan to check oil pick and found a crack on it.
Called my local Mitsubishi dealership and got a new pick up and gasket.
Installed the new pick up and gasket and now I'm getting 60psi when cold and drops to 18psi when normal temp.
Is this normal pressure?

Sounds like you need to take her apart.
