Hello my name is ***** ***** thank you for your question.

Did you replace the throttle chamber? Also the crank sensor you installed, did you have a code for that also? Where did you buy that part?

Purchases part from autozone do I need to reinstalled throttle body back on
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

First off, I am not a fan of after market electrical parts. They never tend to work right. But if you removed the new throttle chamber, yes, we need to re-install it and clear all the codes. Then start the car and let it idle and run to warm up

Can you do that?

Ask Your Own Nissan Question
Customer reply replied 2 years ago
Doing it now after clearing code crank car see how long it will run
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

If it still doesn't run, do you have your old Crank Sensor?

Did you have a code for that and that is why you replaced that also?

Ask Your Own Nissan Question
Customer reply replied 2 years ago

Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

Lets put the old crank sensor in and put the new throttle chamber on, and then see if it starts and idles

Jay with plugs out engine only one revolution battery charged hard to think starter went out
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

Engine will not turn over with spark plugs removed?

Ask Your Own Nissan Question
Customer reply replied 2 years ago
Nope u mention something bout fuses
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

So I understand. With no spark plugs in the engine, the engine will not continually turn over? I am starting to think the engine jumped time and maybe hitting a valve which is stopping it from turning over.

Let me know.

Ask Your Own Nissan Question
Customer reply replied 2 years ago
Maybe taking time to manually try to turn engine over let u know in a few
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

ok.. Yes, make sure the spark plugs stay out and manually try to turn the engine. If at any point you feel resistance, stop!!!

Ask Your Own Nissan Question
Customer reply replied 2 years ago
Turn engine over by hand valve not hitting
Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

Is there a tight spot? Meaning when you turn it manually there is a couple spots that feel tight?

Customer reply replied 2 years ago

Nissan Mechanic: Jay, Nissan Technician replied 2 years ago

The other is inside.

So the engine turns over ok now, it just doesn't start. Is that correct?

Did you put that original Crank Sensor back in?

Ask Your Own Nissan Question
Customer reply replied 2 years ago
