Have Toyota Questions? Ask a Mechanic for Answers ASAP
Thank you for trusting us with your questions. Can you explain to me, in detail, what is happening? Does the engine crank and not start? No Crank? etc....
When you jump started it, did it start normally? Was the battery properly load tested or just charged? Is there any chance that during the process of the battery removal or jump starting that the battery terminals got shorted, even for just a split second?
Does this vehicle have an aftermarket alarm system? Do you know if they load tested the battery? A battery can be charged, but still not have enough power to start the vehicle if the battery itself has an issue. Any chance the terminals got shorted?
Do you have access to any diagnostic equipment such as a digital voltmeter?
The jump box you were using, how big is it, in amperage? It should say on it somewhere. Check to be sure the check engine light comes on when you turn the key to the on position. Since you had the battery charged, have you attempted to jump start it again?
