So it turns over but wont start sometimes. Have a fuel pressure test done on it. Some of those older GM's had a "pulse dampener" on the fuel pump that when bad will by-pass pressure, unless the pump is completey submerged in fuel. If fuel pressure is the problem, the new pump should have a piece of injection hose to take the dampeners place.
