I bought the car a week ago hasn’t ran for a while
Car cranks but doesn’t turn over
i got it to start on starting fluid but there is no fuel pressure I replaced the fuel pump still doesn’t turn over
can any help me with pictures If you can

 

Can you confirm that you have source voltage with the key on at the fuel pump connector when the jumper pin is installed in the yellow connector next to the right side strut tower in the engine bay?

 

i agree. check to see if the pump is actually working.

manuals and wiring diagrams:
Foxed.ca - Mazda RX-7 Manuals

 

Check that you are getting proper voltage to the pump. Should the the Blue wire on the harness side of the connector and should read about 10V while cranking or you can jumper the test connector in the engine bay which should allow you to activated it without cranking I believe. Theres a write up on how you should rewire your fuel pump if you're getting low voltage. You should also check your fuel filter. Its too easy and too cheap to just not give it a shot.
