Its a manual / mechanical fuel pump. To check it remove it a look inside. It will be obviouse if its bad. More importantly if its running its not bad. There are no injectors on a 87 Grand Wagoneer. Its corroborated.
If it has a 360 motor the mechanical fuel pump is located below the distributor. there could be an after market electrical fuel pump located near the tank. these answers are based upon my 89 grand wagoneer with a 360. The fuel pump on an 88 Wagoneer is in the fuel tank itself.
