Thanks for the help guys I need to get this straightened out...
That is how my fuel pump went in my old Buick. Drove around all day and when I went to start it...nothing. Just one of things I guess...

Well, it is a Overkill PCM...isn't there something for a generic temp. setting or a factory temp. setting in the PCM? Just wondering as I don't know tuner systems very well...
