Put new starter on and battery lights won't come on nor will the car turn over. some rats build a nest in the engine compartment, so i do know how to get the car to start. help me please.

Daniel, If battery is known to be good, could be bad connections at battery, starter/solenoid, or ground on engine/frame, battery cables also could be bad with build up of corrosion internally. Check the attached links,instruction and guides, Good luck

Check starter relay in the fuse / relay box in the engine compartment .Do you know what a starter relay is ? Go on youtube an look at video on testing . Engine Won Start No Crank Diagnosis Troubleshooting Starting System Issues

Park neutral safety switch maybe be the reason for the no crank ! Try putting the vehicle in park ,then try to crank the engine . Testing the electrical circuit is the best way to trouble shoot this problem , along with do a voltage drop test on the starter circuit ! This will test the battery cables an connections .

How to voltage drop test starter motor circuit
Does it have a manual or automatic transmission ? Manual ? clutch switch . Looking at a wiring diagram I also see a starter cut relay !

Then click the search button , then click the blue link ! Check the starter cut relay also . Videos on youtube showing how to test a relay controlled circuit !

does it crank if so then it is not the starter. a car needs 2 things to run. gas ,air,and spark. is there a buzzing noise in the gas tank when you turn the key. do you know if you have spark to the spark plugs. if you have no spark then you need a crank position sensor

You can check the starter if it don't start take a hammer in hit the front of it then try to start it if it starts you know it's the starter next time it would help to know the make and year of the car if you can get to the starter if not have it check at a shop

well if you have a dvom/voltmeter check the power at the starter terminals. the main terminal should have power all the time the key wire should have power only when the key is turned to crank engine. if you have power at both then i would start looking at grounds

Could be the switch, or a wire may be shorted.
Try tapping the switch mounted at the brake pedal; also examine the connector and wiring from the switch.

I have had rats building nests in the engine gnawing the wire harnesses and wires. Sometimes they create a short circuit, sometimes create open circuits!

If the start is not grounded it will not turn over the motor check battery cables going to start. There are no reset switches .

oh boy that's a big problem wiring can be such a pain ,OK do you have dash lights ,if so,their is ignition wire that goes from the base of the fuse box to the starter if you could find it ,trace it all the way to the starter make sure that is no chewed spots on the wire .If there is no lights check bye the battery terminal and trace the big red wire to the fuse box and make sure that your main fuse is not blown, also make sure that the wire is not cut either ,well let me know ,

hi is it automatic and won,t start that mean won,t turn over or turns over but won,t start ? how occasional yates210456
