One day car loss acceleration wouldn’t speed up. Got home now it won’t start. It cranks but won’t turn over.

Welcome to 2CarPros.

First, take a look through this link. It discusses the most common causes for a crank no start condition.

Based on your description, it sounds like a fuel related issue, but we need to confirm that. Here are two links. One shows how fuel pressure is tested and the other explains how to check for ignition spark. One of these two things is most likely missing and causing the no start.
