Need wiring diagram for 2000 dodge neon Car won't start. Changed starter and starter relay. want to check ignition wiring.

Here is a link to the wiring diagrams, look it up. http://bbbind.com/free_tsb.html

How do you know that ? safety nuetral switch and relays are all good . Did you check then with electrical testing ? Battery , battery cables , connections ! Voltage drop testing the starter electrical circuit ! The engine starter motor relay in the under hood power distribution center is good ? Is fuse # 11 good 30amp ,
Starter Voltage Drop

Do you know what a wiring diagram is an how to read one ? How to test automotive electrical circuits ?

If you want to fix cars you really need to lean how.

How to read an electrical diagram Lesson 1

Is it getting fuel? Check the pressure regulator or the fuel pump. Even if you have the plug wires on wrong it should do something.

The circuit you hear powering up for two - five seconds should be the fuel pump priming the fuel system . What type transmission ? manual or automatic ? Do you know what a wiring diagram is an how to read it ? Free wiring diagram's here http://www.bbbind.com/free_tsb.html Enter vehicle info. Year , make , model and engine size. Under system click on engine then under subsystem click on starting .Click the search button then the blue link . If you look at this diagram you will see the fuse at the top of the page that powers the ignition switch . You will see the ignition switch , the starter relay and the PCM - engine computer ! The PCM supply's a ground to energize the starter relay . But only if it see's that the transmission is in park or neutral ( automatic trans ) Or the clutch switch is closed ( manual trans ) .To see this you would need to go to transmission controls under transmission/transaxel . Plus the PCM will not energize the relay if there is a anti-theft system problem . You could do testing right at the relay base (where the relay plug's into ) With a test light ,voltmeter etc...

I had a similar problem where the battery was ok but there was no sound from the starter and also there no lights on in the dash when the key was turned. Checked the fuse and checked wire from the fuse back to the ignition switch. The wire from the fuse was ok in fuse box but had no voltage at the ignition sw. The was also no voltage to terminal 30 in the starter relay. Ran a new wire from the fuse to the ignition and it fixed everything. Check for voltage at terminal 30 on the starter relay

Start by checking battery voltage, should be 12.5v to 12.8v. Then check battery draw, use a voltmeter on the battery while trying to start the car and watch the voltage drop, if drop is below 9.6v, it's not enough to start the engine and you will have to get your battery load tested. If there is no or very little voltage drop, then check the starter wire on the starter with the voltmeter, if the readings on the starter wire is battery volts, then you may have a bad starter. If no or very little volts at the starter wire, then go to the power distribution box and check for a faulty starter relay. Good luck, Gary

Check the battery cables if there ok then check the fuses there is one for the start that migh have ben blown

Try the ignition switch (the actual part with the keys). You can actually try starting the car without using the keys. You can do this by hot wiring.

sounds like your not getting power to the starter. check the connections on the battery and the starter to see if any thing is loose. if not you could try taking off the starter, and taking it to a part store and have them test it.
