I have a 1993 ford ranger and I was moving across yard and it shut off by its self and I check fuel rail had no fuel so I check all the relays and fuses and the interia switch all fine I switched relays and che, ked fuel pump it works
No fuel check the fuel pressure with a gauge to rule out the fuel pump-

Does the pump receive power? If not, is the relay being energized? If so, you'll have to trace it.

Ya the fuel pump work and I get no power to pump I switched relays and nth

Check the inertia switch

You haven't answered the questions yet.
Is the pump receiving power?
What is the fuel pressure?

I'm going to take this to mean that you've both hotwired the pump and the relay to verify that the pump works. With the key in the Run position, see if you get power to pin 86 and that pin 86 is properly grounded. IF not, find out why. Trace the wire for Pin 86 back to its source.

Has no pressure and fuel pump harness has no power

Jump out the relay and test for power at both sides of the Inertia switch.
