Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.I assume your spraying fuel into the throttle body as you should not have a carb because this engine should be fuel injected. In order for the engine to start and run you need good spark to the spark plugs, injector pulse and proper fuel pressure so since it will run with add fuel I would start with checking for injector pulse at the injectors when it will not start. You can do this with a standard 12 volt test light by placing the test end in to the power side of any one of the injector and the ground end into the other side and then crank the engine over. If you have injector pulse the light should flash. Check this for me and post back with the result and we can work from there.
Yes both of these are throttle bodies if you look on both side of the intake you will see the injector rail which holds the injectors into the intake.
