Its been sitting for about ten years. It will start right up sometimes and run great!! Other times it wont start at all. When it does not start it is not getting any power to the fuel pump. When it starts, it is getting power. I found that if the fuel pump quits working, if you tap the computer under the hood, the pump will kick back on momentarily. Is this something that can be fixed or does it just need a new computer? Thanks a lot guys!!
