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?

Customer: replied 1 year ago.
Replaced throttle body same problem unable to relearn system instruction tell me that engine need to be warm purchase both pae
Expert:  Jay replied 1 year ago.

Did you clear all the codes first?

Customer: replied 1 year ago.
Purchases part from autozone do I need to reinstalled throttle body back on
Expert:  Jay replied 1 year 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?

Customer: replied 1 year ago.
Doing it now after clearing code crank car see how long it will run
Expert:  Jay replied 1 year 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?

Customer: replied 1 year ago.
No their was no codes for crank sensor just trying things installed new throttle clear code a d replaced crank new sensor with old one what next
Expert:  Jay replied 1 year ago.

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

Customer: replied 1 year ago.

Customer: replied 1 year ago.

Expert:  Jay replied 1 year ago.

So the engine won't keep turning over on it's own?

Expert:  Jay replied 1 year ago.

Expert:  Jay replied 1 year ago.

Ok.. Does the car start and idle?

Expert:  Jay replied 1 year ago.

Did you try clearing out all the codes and did you put that original crank sensor back in?

Customer: replied 1 year ago.
Jay with plugs out engine only one revolution battery charged hard to think starter went out
Expert:  Jay replied 1 year ago.

Engine will not turn over with spark plugs removed?

Customer: replied 1 year ago.
Nope u mention something bout fuses
Expert:  Jay replied 1 year 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.

Customer: replied 1 year ago.
Maybe taking time to manually try to turn engine over let u know in a few
Expert:  Jay replied 1 year 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!!!

Customer: replied 1 year ago.
Turn engine over by hand valve not hitting
Expert:  Jay replied 1 year ago.

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

Customer: replied 1 year ago.
Jay replaced battery turning strong crank not start see one fuse box under hood by battery where is the other
Expert:  Jay replied 1 year 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?

Customer: replied 1 year ago.
Nope do I need too
Expert:  Jay replied 1 year ago.

Yes, I have been asking you to that a few times. I don't trust after market sensors.

Customer: replied 1 year ago.
Ok give me a few
Expert:  Jay replied 1 year ago.

ok

Customer: replied 1 year ago.
Ok done it crank after several turn it's runs rpm get 1500 then die off
Expert:  Jay replied 1 year ago.

Ok.. Will it start and idle? Does it have the new throttle chamber installed? Has all codes been cleared? Did any return?

Customer: replied 1 year ago.

Expert:  Jay replied 1 year ago.

See if it will start and idle with the throttle body unplugged.

Customer: replied 1 year ago.

Customer: replied 1 year ago.
