1987 ford f 150. Fuel system not responding when key is turned. No fuel pumps working. I think the relay may be working cause I can here it click when I turn the key. Could be ignition relay though. Fuel system not pressurizing like it should. Motor turns over, just won't start. No leaks in fuel line or filter. No fuel pump whine when ignition is on. Tryed both tanks but nothing. 4.9 L. 300 straight 6. Inline 6, whatever!!

Your fuel pump is turning on for that few seconds as the key turns to the on position, if not, the connector to the fuel pump the wires are shorting out, or disconnecting within, the wire, will have to replace wires, to pump, or replace the pump, also, check the relays between the air cleaner box, and, the brake master cyl., black cover with wires coming out the bottom, those relays wires could be breaking down. "try before you buy it's cheaper"
Is the fuel pump inside the fuel tank? If, so, you could try disconnecting the wire harness at the tank, and hot-wiring the fuel pump directly to a 12 volt source, in the correct polarity of course! If the pump runs, your problem may be a fuel pump relay, or a wire problem or connector problem. If the pump does NOT run, post that info. There may be a way around the problem!
Take the drivers side kick panel off there is a fuel safty cut off it is a gray box with a button on top push the button in see if it starts if not check the plug in the box to see if it is burnt my ford f 150 is a 87 and thats what happened to it hope this helps
