fuel pump will not turn on. i put my hand on the relay to see if it clicks and it doesnt the hot lead is getting power but non of the rest of the wires on the relay have power with the key on or off. help i need my car for school. i already replaced the fuel pump and relay

anything else in terms of electrical not working? radio, heat controls, etc? anything to do with key-on power source.

If the TFI module is bad on the distributor, it may not come on either.

all other electrical conections work. the fuel pump started to come back on i dialed the fuel pressure to 6psi let it idle for about 4min then the fuel pressure went to 15 and everytime i steped on the pedal went to 8 then i shut it off tryed to turn it back on and the fuel pump wont come on again

6psi? are you running carb? you have ZERO vehicle info in your signature.

You do have a return line I hope. That is a lot of pump, especially for a carb.

What ignition does the car run?
