Well after two years of building this car it wont start. When I first tried to start it nothing. My bubby put a scanner on it and it wouldnt even talk to the computer. He ran a wire from the negative battery post to a conection where the scanner plugs in and we got 40 lbs of fuel pressure and spark but still no start. He said it sounds like a computer ground problem. I had a chip on the computer and took it off to see if that made a differance nothing. I am out of ideas. The scanner says everything is ok no codes?
