Changed the alternator, fuel pump, ignition coils, spark plugs, idle air control sensor, and the battery. Ive tested all the relays with a tester and checked all fuses. Also checked injectors to make sure they are opening and closing. The car would start and run until you shut it off then it would probably start the next day. Ive had the engine control unit rebuilt. Now it won't start at all! Help?..

Hello, Do you mean the engine is cranking but not running correct? If so it sounds like it can be the fuel pump or crankshaft position sensor. Do you have any codes? Please go over this video to get us started on finding the problem.
