Can anyone please help me on this one,
I have a 93' camry and after putting gas and try to start again, the car didn't start.
I check the fuel pump and replaced beacuase I thought it was, but after checking everything
fuses Ok,
No spark
No gas (I put direct current using a wire from the battery positive to the wire positive to the pump and the pump starts, so that means that I have no current to the wires of the pump and no spark too)
I wonder if there is any main relay/fuse that controls both the gas pump ignition and distributor sparks
somebody please help me on this.

Which engine? Have you checked for OBD fault codes? Procedure is in the Factory Service Manual thread at the top of the forum.

I would suspect you lost the RPM signal to the ECU. This will cut off spark and in-turn via the ECU and circuit opening relay, power to the fuel pump. It's a fail safe mode designed to prevent engine damage and excessive emissions.

It is a 4 cilinders, I haven't checked the fault codes, this car has passed though a lot of damage, it doesn't have sterero, with a lot of cables in it.

how can I fix the RPM signal or/and circuit open relay?

First you have to check for error codes to verify which direction to go.
