In the fuse-box which is located in the lower left portion of the dash. (approximately above the driver's left shin). The door to the fuse box is labeled "FUSE BOX". It can be removed quite easily (no tools). On the back of the door, there is a map of fuse locations.
You may have a bad fuel pump relay or a blown fuel pump fuse.
Should be slightly in front of the rear axle, passenger side I belive. Has a cover plate underneath it, 3 ? bolts holding it.
there is no fuse on an 85 caprice for the fuel pump because it is a machanical pump driven off the motor ITS CARBORATED RIGHT if fuel injected don't no that's what i know based on my 86 caprice classic 305
There is no "reset" switch for the fuel pump on that vehicle.
measure voltage before it goes to the pump, either at the fuse of just before the pump. if voltage is for example 12v at the fuse then 8v after the pump then yes you need a new pump. if voltage is 8v at the fuse or before the pump then its not the pump and you have some other electrical issue. not sure if they have a relay on your model dude, on a third gen you have (in order of electrical flow) the follwoing electrical components Battery, Ignition Switch, Fuel Pump relay, Speed Relay, Fuel Pump Resistor, Fuel Pump Fuse, Ground located in boot (near pump) measure the voltage at each of these locations and you should be able to see where the fault is.
If the engine is fuel injected, it is an electric pump and is located in the fuel tank. If not, it is located on the engine block and is a mechanical pump.
Under the hood, on mine.
the 1986-87 lg4 engine had a mechanical fuel pump and an electric in tank pump.
I own an 86 s10 blazer. if its the same there should be a fuse under the steering wheel in the fuse block. it should say fuel over it. >>PREVIOUS ANSWER<< I'm not sure it has a fuse it has a relay i believe and it may be located on drivers side fender
If the inline fuel pump can deliver a constant 9 to 13 psi it should work. Wire it to the original fuel pump wiring harness and mount it as close to the fuel tank as possible.
85 was carbuerated..86 was first year of EFI....should be fuse number 8 on driverside kick panel.
The 86 has a mechanical pump. There are no electrical connections.
Mounted on top and inside the fuel tank.
GM vehicles do not have a fuel shut off/inertia switch
i believe it should be around 6 psi that's what mine was at after i installed my new pump

Which engine do you have? I believe the 5.0 liter V8 has a mechanical fuel pump, but I am not sure about the 4.3 liter V6.
It doesn't have one.
It's next to the fuel pump, behind the rear right tire.
THE FUEL PUMP FLOAT HAS GONE BAD OR THE GAUGE NEEDS TO BE CHECKED
Is there more then one fuel filter on a 86 190 D ?
fuel pump or ignition
Assuming it didn't run before you replaced the fuel pump... three things. 1. Bad fuel filter and maybe it didn't need a fuel pump. 2. Bad fuel pump. (it happens) 3. Something else is wrong. Suggest you check for any codes of the computer.
