2001 Prius all the lights come on with a brand new 12V battery but won't start!

The car was driving just normal until I changed the gear to reverse it too suddenly before the car made a complete stop. It died immediately in the middle of the street and it won't start or if it starts it dies in a fraction of a second but all the lights come on and also the engine oil light starts blinking even though there was no issue with the engine oil warning light and there was enough engine oil. now i changed the 12V battery since i had still under warranty and still with this new battery the same condition exists. the vehicle has 150K on it.

help please

thanks in advance.

 

a mechanic hooked up to the code reader and said there was no issue meaning it didn't show any code

 

thousand times agreed with you about the stealerships, those are for the wealthy people, who money isn't concern. their fees are most likely even more than the value of the car itself so its no go there for me and to tow it back and forth is close to $200 i don't have. I'm also trying to avoid regular mechanics since they also tend to over charge and mislead, thats why i don't mind doing the job myself if I know what the problem is.

an skilled mobile mechanic have already tried the code reader and nothing came back and he told me he had to diagnose it a more convenient day for him but i'm unable to get hold of him or any other mechanic that I can trust or afford thats why I'm here looking for help since its weird how things transpired.

(1) the car was fine, (2) sudden change in motion, (3) the car went dead completely while at the same time everything else seems perfect. i don't know how one thing led to another, I can't connect between what happened and the results.

 

Toyota Techstream software or Dr. Prius app...

Are those apps that I can use for iPhone? If yes, how?

make sure your battery charges all the way up to 13.8 volts with a charger.

Using with other car with a jumper cables?
