Why does Ford Ranger use returnless fuel system?
It’s generic, which means that it has the same meaning for the Ford Ranger as it would any other vehicle. This code is most common on vehicles that use a returnless fuel system. This means that the fuel pump adjusts the pressure going to the fuel rail based on the demands of the vehicle, therefore eliminating the need for a return line.

Misfire – Without enough fuel pressure, your Ranger is likely to misfire. If it is misfiring, you’ll likely get P0300 (random misfire, all cylinders) along with the P0087 that brought you here. As long as you fix the lack of fuel pressure, the misfire should take care of itself.

Why does my Ford Ranger run for a little then dies?
Next check is the fuel pressure regulator, your looking for fuel coming out the top and bleeding into the vacuum line thus flooding the engine. Another thing that happens is the distributor pickup coil can fracture, it runs good until it gets hot then it will go open and the engine stalls, and the ignition module can act the same way.
How can you tell if your Ranger’s fuel pump is going out?
The only way that you are going to know that your Ranger’s fuel pump is going out is that it is no longer providing enough fuel pressure to keep the engine running under a heavy load, or at high-speed. Typically, if you are heading up a hill (or accelerating) the engine may start to feel like it is just running out of steam.
