I have a 1986 ford club van that will not start because the fuel pumps (it has 2 tanks) are not turning on. I checked all relays and the inertia switch and fuel shutoff switch as well. I'm wondering if I have to put more gas in the tanks to make the pump turn on in the tank that I wish to use. This is either something really simple or a royal pain in the $^@, I know it. Appreciate your expertise
Did you try taking the pumps out and trying them individualy? cuz they myt b broken.. and besides you dont need to put more gas cuz you should hear them turn on especialy with the tank open./ . . . . cuz if all the wires are ok, its gota be a prob with the pums. . and you do have an old van. . 8)

Open gas cap and turn key forward and listen for the fuel pump hissing noise. If its not there the fuel pump is out. (OPTION) Take heavy object like a club or tire Iron and bang plastic fuel tank in the middle. Several blows will be required. The idea is to shock your fuel pump into working. If it works then get it to a repair shop because It most likely will die again.
Hello. They are located in the fuel tanks. I say tanks plural because it's a 350 Club. There is also a pressurized pump on the frame rail just to the inside of the frame, just about under the driver's seat, if it is equipped with dual tanks. It's a rare occasion that one cannot run the van without prior notice of a tank mounted pump going bad. I'd try the fuel interrupter switch located in the passenger's side kick panel before anything else. Push the button top to reset it and then try starting the van. If the vehicle has suffered a jolt, large pot hole, bump etc...
CHECK FUEL PUMP FUSE AND RELAY.IF BOTH GOOD LISTEN FOR FUEL PUMP RUNNING IN GAS TANK WHEN YOU TURN ON THE IGNITION SWITCH.YOU HEAR NO SOUND.SCAN VAN FIRST FOR PCM FAULTS SINCE IT CONTROLS FUEL PUMP IF PCM GOOD.FUEL PUMP IS BAD.IF FUEL PUMP RUNNING REPLACE FUEL FILTER.
Check all of the fuel lines very carefully for breaks or cracks in the fuel lines, especially between the fuel tank and the fuel pump.
If the fuel lines are all in good condition then you can safely assume that the problem is in the fuel pump and you will need to replace it. (If the fuel pump is in really bad shape the engine oil on the end of the engine oil dip-stick will smell like fuel)
When you turn on the key, the fuel pump starts and runs for one second. Under normal circumstances this is long enough the bring the fuel pressure in the fuel rails up to spec. But it is not long enough once you run the fuel system dry. The easiest way to remedy this is to turn your key on and off six to eight times with 2~3secs interval. If there is no problem in the system, this will get the fuel pressure up in the rails and the engine will start.
BACK IN 1986 IF YOU HAD A MECHANICAL FUEL PUMP LOCATED ON SIDE OF ENGINE. YOU HAD CARBURATOR ENGINE.AND ELECTRIC FUEL PUMP IF YOU HAD FUEL INJECTION.ENGINE.THE FUEL PUMP IS IN GAS TANK.OR MOUNTED ON THE OUTSIDE OF GAS TANK.
i would put a fuel gauge on it and check to see if it good or not, your frame pump is what give the engine exactly what it needs. The tank pump only provides fuel to the frame pump. So if the tank supply pump was not working, you would not have any fuel.
