I need to replace the starter on my 2009 dodge

bad starter relay or selonoid

Double check all connections, make sure they are tight. Wire brush the battery connections, make sure the connections on the starter ore good and tight.

Make sure the cables are connected properly and tight. Check for blown fuses, or loose wire connections coming from the battery to the car.

check the connections on your starter and make sure they are tight and corrosion free.. if there is no corrosion and all the connections are tight the the problem is goiung to be that the bendix inside the starter has a flat spot on it causing it to stick and not turn freely... in that case replacing the starter is the the best choice to make..

1st off is it getting spark ?
2 things to try if you have went thru spark,fuel, ignition.
Dodge cars and trucks have a cam shaft sensor, inexspensive and it sends info to motor, (Google it for location) also if your catalytic converter is clogged it wont start/run, bang on it and if you hear loose or ratteling in it then its clogged, punch a hole in it and if it starts then replace that and you are good to go.

if battery is good. you may have a bad wire to starter or the connections are not clean and tight. check the battery ground also.things to check,

The starter is right behind,or above depending on the engine size of the front frame work!Around in the center ! From 1-- 10 about a 5 in difficult remove and replace. And about even with the top of the oil pan. Unhook the positive battery cable first ,then the cable and wiring from starter solenoid. there may be a plastic cover hideing the 2 bolts.Remover the cover,then loosen the starter upright
bolts then remove the one short one on the rear bracket,of the starter,to the lower part of the engine block! Check flywheel for worn teeth,or flat spots, and converter bolts for tightness!

Its on the trans, i dont remember which side, not hard to get off/on, but requires time and a lot of patience.
- try not to throw your tools :) -

Turn the crank pulley make sure the engine is not siezed

Did you check to see if your old starter was any good, you may have a bad spot on your fly wheel and it is getting caught up on the bad spot and it want start try turning your fly wheel of the bad spot and then try to start it.
