My car has really rough starts, and sometimes doesn't at all(just cranks 'till the battery dies). The fuel pressure goes down to where it is in the pic (0 psi) after the car is off for about 5-7 minutes.

What can I do about this, whats the problem?

my guess is that your injectors are shot...

Or fuel pump, or pressure regulator, or a relay. Does it hold pressure and then drop off quickly when you shut off the car? If so, then check the injectors, FPR and check valve to the pump. There's a diagnostic procedure you can follow to pinpoint which one that has been posted 100 times I'm sure. Do a search and you should find what you need.
