Well could be one of 2 problems it is either the fuel pump relay which is located on the inside of engine compartment on the passenger side fenderwell. looks like a small box there are normally 3-4 of these but if it is original it will be green in color,. if that is not it then it is normally the EEC unit itself which is located inside the kick panel on the passenger side, this is the computer for the vehicle which can be found at a parts store..autozone..

Is there a relay fuel pump switch for a 1987 ford bronco 2 If we straight wire it to the fuel pump it comes on but when turning on switch fuel pump will not come on.


I just had the same problem, today, check the tan- lt green wire on the fuel relay that is located on the right fender, mine wasn't pushed in all the way, this wire shut down spark and fuel, if you are looking for the shut off switch to reset the relay, it is on the passagers side floor board under the dash, gas two wires, orange and pink, I don't remember the color of the stripes, I removed this switch and wired them together without a problem

1987 ford bronco fuel issues


First thing to check out will be the fuel pump relay under the hood. It is the one who drives the pump, so if it is defective the pump will not work either to prime the engine, or to make it run. Secondly, you need to check if the fuel filters are OK cause sometimes they clog up and prevent enough fuel from reaching the engine. Thirdly, check the injector(s) for cloging, and clean or replace them as needed. If none of this helps, then the problem probably has nothing to do with fuel delivery, and the next step to check will be the whole ignition system, which is also one of the most comon bronco problems.

Cant find fuel pump relay on an 1987 bronco 2


The fuel pump relay should be at the pass. fender well. It may be under a cover that holds 3 relays together. Usually it has a green plug on it. Also check the inertia (crash) switch. It's located at the upper part of the pass. side floor inside the car. It'll be under the carpet midway up the firewall. Make sure it hasn't gotten tripped.
