The 87 doesn't have a ballast resistor and is wired a little different than the 88-90.
Turn the key to the run position, the fuel pump should power up for a few seconds to prime the fuel rail. Then when the key is in the start position the fuel pump relay should close again as soon as the ECU gets a pulse signal from the CPS.
Check for spark while it is cranking, no spark or fuel and it is likely to be the CPS.
The main power for the fuel pump relay is from a fusible link. If a fusible link goes out, it is likely to affect more than just the fuel system. Fusible links are like master fuses and when they blow will shut down multilpe sub system
If I remember correctly the ground for the pump is near the pump and a sheet metal screw through the floor pan. I may be wrong, but I do remember the ground is nearby.
The power between the fuel pump relay and the pump goes through a couple of splices and connectors. And the wire changes color from orange to orange with a stripe and pink with a stripe.
