Its a 1997 Chevy Silverado 1/2 ton 305. Monday went to start it and it would'nt. Plenty of elect. sounded like it was starved for gas. Went and got a fuel filter (which had been changed less than 3 months ago) replaced and it started right up. Today same problem will not start. I have taken the filter off 2 times, still wont start. Help?! The dang thing is at work, my wife works same place, I nights her days, so I have a car. I guess it could be the fuel pump? Is there a way one can tell whats wrong.<br />Thanks.
