How do i check the fuel pressure and with what tool, can i do it with a standard fuel tester? What should the psi be. Thanks!

Re you reffering to the high pressure side or low pressure?

High press use EFI DVTs and ramp rail pressure up to 160 mPa.
And log rail pressure with scan tool.

Low press you would need a lift pump and then check at the port on the front by the alternator or T off the fuel hose somewhere as close to the cp3 as possible
