I have a car that has an on time payment system attached to it. I make my payments but my car still will not start. I had it taken to the machanic, where it sat for a month and finally he gave up and told me that he was unable to diagnose the problem. He told me that there was nothing wrong with my starter which was thought to be the problem, and it was most likely the pay box on my car malfunctioning and over-riding my anti-theft system. Now the finance company is trying to settle the account with me because they believe that the equiptment is faulty, and in doing so, they have increased my payments by $250 per month untill it is payed off. I am looking for a way to over-ride the the system to trouble shoot my car since the finanace company will not agree to let the machanic do it temporarily. If it starts I know that it is the pay system and the finance company will have to remove the box early due to a breech in contract. However if it still doesnt work them I will take it to volvo for and evaluation. please help,I cant seem to find emi sheild or faraday cage bags to test. any info is helpful
