Turns over but won't start

Hello, it's absolutely impossible for anyone reading your concern to give you any valid advice. Since you've swapped an engine there are so many questions that cannot possibly be asked or answered here to give you any guidance. Some of those questions would be: where did you get the engine? Is it new or used or rebuilt? Did you keep all the electronics and wiring and components with your old engine or replace it all? You'll need to consult a local shop near you for hands on assistance. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
