/\ Repair manuals.Electrical problems are not gonna be easy to diagnose over the internet.My advice is to buy a multimeter (if you don't have one yet) and start checking sensors.Crank and oil pressure sender would be the ones to start with first.Then check the injectors and coil packs next to seee if they are getting voltage.You can get injector"noid lights" pretty cheap.They plug into the injector harness and will light up when that injector lead is being energized.Also when you turn the car to the "on" position can you hear the fuel pump prime?You should always hear the fuel pump prime for about 5-10seconds and shut off when you turn the car to "on".If not the relay might be sticking or going bad.The relay is located in the passenger kick pannel by the door hinge.It's green.
Also no need to triple post your problem.Your well on your way to irritating the modderators as well as everyone else.........
