I am no expert but have just experienced a similar need to find the switch. I am assuming you are looking for the shut off switch which may 'trip' for example if you were in an accident. I found mine, [[1994 Ford Bronco - 351 engine - Eddie Bauer edition] located as follows: Open the passenger door. Looking under the dash board, just in front of the door opening [A-pillar] along the wall you will see a plastic trim piece held on with a single 'x-mas' tree type fastener. You will see along the top of the trim piece, [referred to as a cowl in the owners manual] a semi-circle molded into the top edge of the plastic trim. Try reaching your finger into the hole and locating the switch. It is located just [barely] within reach of your fingers. You should feel downward with the tip of your finger. If you cannot feel it, you will have to remove the trim piece [most likely breaking the fastener - as I did.] p.s. - wouldn't you know it, the switch is not my problem. good luck
AnswerI just had the same issue . Check for a bad ground at the front of the block or for the body ground. The crank sensor is located on the left upper side of the bell housing,try checking that first. You can also check the asd relay in the engine compartment located in fuse and relay box. there is also a 20 amp fuse for it in the same box. If your gas gauge is not working no fire or gas the problem is the crankshaft position sensor.
If you apply 11-12 volts directly to the pump and it does not run, it is a new defective pump. Return it an get a replacement.
Usually that means that the fuel pump motor is failing and draws too much current. Whatever you do, don't put an oversized fuse in the circuit. That would be a big mistake and cause great risk of a fire. Just replace the fuel pump.
