Any applicable mil codes? Do you have primary voltage to the coil, pink wire, goes hot when you turn on the key? Use a gage and check fuel pressure, some of the national brand autostores used to loan out a fuel pressure gage, if you don't have one. If you have TBI use a TBI fuel pressure gage. At the datalink connector, terminal G, where used, is a test connector for the fuel pump, use jumper wire with inline fuse connected to battery voltage, touch to terminal G, pump should run, no need to use key. To check for codes, tune the key to on, no crank, use a jumper between terminals A & B at the datalink connector, the mil starts flashing, you count the flashes to get the codes. Your looking for two digit codes.
