I think the film you're looking for is: Chances Are.

"Young D.A. Louie Jeffries is hit by a car and dies in 1964, but manages to slip by the pearly gates and is instantly reborn. In 1987, 23 years later, his widow Corinne still misses him, ignoring the frustrated devotion of his best friend Phillip Train, who has pretty much raised his only daughter Miranda as his own. Miranda, while a student at Yale University meets Alex Finch, who works in the library but is about to graduate. After graduation, Alex schemes his way into the office of newspaper editor Ben Bradlee, at which time he meets Phillip, a journalist at Bradlee's newspaper. When Phillip brings Alex to meet the Jeffries family, Alex quickly realizes he is in fact Corinne's dead husband reborn.

His memories of his life as Louie return just as Alex begins a romantic involvement with Louie's (his) daughter Miranda. Instead, Louie then spurns his daughter's advances and begins romancing his widow Corinne, frustrating Phillip's attempts to court Corinne, and resulting in a number of comic mixups."

It's definitely Chances Are starring Robert Downey Jr., Cybil Shepard, Ryan O'Neal and Mary Stuart Matheson. One of my favorite 80's movies.
