1998 Nissan Pathfinder wont starte

Sir-when you turn key to run do you hear the fuel pump buzzing for a few secs? If so check the fuel pressure make sure its within specs-if okay check for injection pulses have helper crank engine over and check the injector/s if its clicking or use a noid lite-is it clicking/noid lite flashing? If all checks are okay-disconnect a plug wire ground it and have helper crank engine over -Do you have spark? If not check and test the following item Coil/Coil packs/distributor pick-up coil, ignition control module, camshaft/crankshaft sensor, if item don't apply disregard it
