Check to make sure that everything from relay to pump is working correctly. In other words start by checking to see if the relay gets power (test with meter but you will also hear the audible click) when the ignition is turned ona and looses power when ignition is turned off. If the relay is working off the ignition then you problem is between relay and fuel pump. Use your twelve volt power source to test the relay and verify that putting power to the relay operates the fuel pump. If all is well between relay and pump just not getting power to relay when the ignition is turned on then start tracing from relay back to ignition. If you need a wire diagram I have one for a 88 and have a service manual for a 86 so between the 2 I could probably shoot you some pictures of the wiring diagrams and fuel pump diagrams. Also make sure to check all grounding to make sure it isnt just a loose ground or one getting a bad connection due to corrosion. Good luck!
