1994 NISSAN PATHFINDER WONT START I LIKE TO FIND OUT HOW CANT I BY PASS THE MANUFACTURE SECURIETY SYSTEM . BUT I HAVE INSTALLED A AFTER MARKET ALARM AND I HAVE A BRAND NEW STARTER, ALTERNATOR , BATTERY AND STILL WONT START WHAT CANT I DO TO GET IT WORKING. THANK YOU FOR ALL THE HELP.MY NISSAN PATHFINDER I REPLACE THE IGNISION WIRE AND STILL WONT ALL THE PARTS I INSTALED IN MY PATHFINDER AND STILL WONT RUN WHAT ELSE CANT I DO

First thing you should have done was check and test.NOT REPLACE PARTS.Did you test the battery to determine it needed to go? Had the starter failed to turn the engine over? The Alt supplies current to run the vehicle ,and keep the battery at the proper state of charge. How did you decide on ign wires verus the other ign components? Did it start and run okey ,before you added the after market alarm? If yes, I guess you know where some of the issues are!
