The FBI investigation was delayed because of Bill Clinton firing Sessions. The first investigation was not the FBI so the autopsy was tainted.
How was the autopsy "tainted"? It was performed by Dr. James Beyer, Deputy Chief Medical Examiner of the Virginia Office of the Chief Medical Examiner, the day after Vince Foster's body was found. Dr. Beyer had performed over 20,000 autopsies.http://www.washingtonpost.com/wp-srv/politics/special/whitewater/docs/fosterva.htm
The Park Police performed the initial investigation because Mr. Foster's body was discovered in Fort Marcy, a park maintained by the National Park Service and thus they had primary jurisdiction. But:
The FBI assisted the Park Police in certain aspects of the ensuing death investigation, as did other federal and Virginia agencies. Moreover, the FBI, at the direction of the Department of Justice, opened a separate investigation of possible obstruction of justice after a note was reportedly found on Monday, July 26, 1993, in Mr. Foster's briefcase at the White House.

Sorry, there was no delay because of Sessions' firing (the FBI has almost 35,000 personnel including 13,000 special agents), the first investigation was assisted by the FBI (as the voluminous files I linked to in the prior post attest to) and there was nothing to "taint" the autopsy which was performed by the appropriate, well-qualified official. Five separate investigations all reached the same conclusion: Vince Foster committed suicide. A list of those five investigations is contained in this article: https://www.washingtonpost.com/news/fact-checker/wp/2016/05/25/no-donald-trump-theres-nothing-fishy-about-vince-fosters-suicide/
