Oh ya you definitely have to have the computer and the complete wiring harness for the new engine. 00-02 was the new body style and new engine in 03 they modified the body style and the engine. IT is a hard transfer but very possible. Good luck

SOURCE: my 03 dodge neon has jumped time. What do I need

Most mechanics would pull the spark plugs and check the compression in the cylinders, but usually anyone with a trained ear can tell by the sound of the starter when cranking against the compression of each cylinder. Many of the smaller engines today have valving designed so that when they are out of time, the pistons interfere with them. That means two objects try to take up the same space at the same time and at minimum the valves bend. Worse case scenario would be upper head/camshaft damage and possible piston damage. That's pretty severe. You won't know until you get the valve cover off or maybe deeper. Hope that helps.

SOURCE: 2001 Dodge Neon won't start. says "fuse"

check all you r fuses. There should be 2 sets, one under the hood and another in the passenger area(driver side under dash usually)

SOURCE: the speedometer and odometer dont work..can this

Sure, it's probably just a loose or broken speedo cable, it runs from the transmission to the firewall. A mechanic can fix it in minutes.
