Robert Montalvo Sold a Vehicle that does not run. Pasadena , Texas

Purchased a 1999 Licoln Navigator cash for $4000.00.  Vehicle was found on Craigslist and Autotrader as a good running vehicle and dependable.  After the sale when i got the vehicle home the interior light would not shut off draining the battery so i was unable to drive the vehicle the second day i had the vehicle.  Contacted the seller and he came over and gave me a boost.  Drop the vehicle for the second time and the enginee check light came on.  Took it to Auto Zone to verify the problem per the sellers request, and found it had a fuel inject problem.  Contaced the seller and have not heard from him since.  Now the truck sat in an airport garage for a week and i got it home and now it won't start again.  Its not the battery.  Have tried several time to contact the seller via phone and email and have had no response back. 

before purchasing i checked carfax, and DMV for any damages and any other faults with the vehicle fand found none.  The seller sent a response that he would help to solve any issues because he did not want me to feel like i was ripped off.  I have had the truck for less than 3 weeks and have only had the pleasure of driving it for only 5 days total. 

I have asked him if he would please call because i needed my money back because i needed a dependable vehicle to transport my kids to and from and i needed to get to work daily.
