On my 84 convertable mustang 5.0 L, the fuel pump is not getting power i dont know where to look for the power switch that turns it on and off. do you have any ides on where to locate this switch or what to look for?
Check in the trunk, probably on the driver's side. It should be a round red push button.

Can't find button in trunk,or under seat,or on firewall,or????????????. My son pulled radio out and replaced when this trouble started, i looked all up in there and see no switches or disconnected wires ect.really sittin in dark here , by the way it is a rag top.
I feel so dumb,car won't run,can't find red button so can't do nutton.So if you can help me get back on the road it'll sure ease my mind of this big load.
There isn't a fuel cutoff switch for a carb motor. The fuel pump is on the timing cover, right? Maybe it just needs to be replaced as they do go bad over time.
The red & black wires go from the fuel pump mounted to rear passenger side inside frame to the top of gas tank turns into grey plug into tank.where does the power come from ? and why do wires go into tank if pump is outside tank? i put power to pump it works ok.
Found small pump in tank, put voltage to it and it pumps ok,there is 2 metal tubes coming out of tank, the smaller one comes from pump in tank and bypasses big pump and goes towards motor the bigger one goes to larger pump on rear frame and than to filter than to throttle body,the 2 wires black and pink go from big pump to little pump,they just make a circle around back of tank,i can't find how it gets fed voltage,its a real puzzle,i also think i found the shutoff switch in trunk left side behind metal piece above wheelwell,button is down? 2 wires going to it but they are red and red/blk,both wires hot but cant still not find power source to pumps.
How about that secondary pump, is it working? This could be because of the
fuel pump relay too.
