2009 Scion tC Electrical System Problems

sold a AS IS TRADE IN vehicle that had no warning lights on dashboard or window info on safety defective emmisons and ecm and has not been very helpful with my vehicle I have not been able to drive because of safety concerns with recent discovery of codes that showed after getting a new battery for my new way of commuteing to work and live daily activity like most with a car I laid 2,050.15 and was told many times at test drive that it was amazing running sports car and mentioned he only had to replace valve cover gasket before it was able to be sold and at time of payment with test drive only showing signs of low rpm and throttle idle on test drive so trusting that the owner was telling me the truth I purchased and drove car home I needed gas because fuel was empty and when I went to pump into tank I got major clicking of the handle like my new car wouldn't take fuel for some weird reason owner at dealership was called 5 mins after buying on auto lot to express major concern with pumping gas he again said vehicle was inspected with nothing of concern now finding that it is going to cost many thousands to repair emmisons system And fault codes with total programing with abs and to cost more than anyone can honestly afford now I'm drained of my savings and have no hope of finding a solution so my car isn't parked because of failure of hidden defects I would of never invested my whole savings on a car if information was shown for defective vehicle system parts.i want the owner to honor his misleading auto fraud and in anyway help with safety emmisons compromised part replacement so my vehicle I purchased will drive like promised at business or replace it with a vehicle that is safe for the road without hidden errors I am very emotionally distressed over finding a solution for this unexpected misfortune I've been experiencing life gets very difficult without assess to a safe vehicle it has cost me to much I shouldn't have to suffer for his fraudulent actions

I believe my emmisons had malfunctioning part # 77740-21011 called used auto sales agent 5 mins after purchasing on 3/1 because I was at gas station having unusual fuel pumping problems that made it very difficult to put gas in had a constant clicking happen and the dealer on the phone told me there was no issues with my new vehicle and after checking my warning lights to see if any were signaling and had no active warnings for service engine soon or maintenance so I believed him I drove home and within two days tried to replace my battery because cars battery looked old I disconnected the battery and on accident reset my whole car and with rpm being lo I checked with simple scan tool that I after a accidentall reset to better my battery lifespan noticed I had a entire system code read concerning emmisons I am having a Toyota, Lexus,scion technician visit tommrow to get better understanding because I cant afford to pay the 400 for basic test from Toyota.and it has been 4 weeks since it has been parked at my house because of uncertainty about error codes and if it is safe to drive feel like my purchase had dealer take of warning lights to show major emmisons defect and with the cost to have Toyota replace and have scions system reprogram so it relearns it will cost more than I paid for vehicle I have messaged who sold me vehicle at business in Bradenton since day one of purchase 3/1 and was sold to me as is without any window sticker explaining defects have called Toyota dealership at 3 locations including Sarasota to ask for scion specialist assistance to get my vehicle in driving condition and with my battery reset and it being incomplete until I find exactly why my vapor canister is throwing some unusual codes by experience tech .no insurance representative or manufacturer police with situation with vehicle and it's safety.with 34 calls to places that do low cost diagnostic tests I been told only person that can do what is needed to vehicle is Toyota dealer
