I have a problem with a 2008 Dodge Charger, my battery went bad and I had to jump it off to take it and get a new battery put in but now my new battery won't start my car not even when the new battery is jumped off either. When u try and start the car it reads the key and the dash lights come on sometimes when you try and start it but won't start but when you try a second or third time to start it the dash lights won't come on at all and still won't start. What should I do?

jack it up,drain all the oil.take all the bolts off,scrape all the gasket off without damaging the metal,put new gasket and pan on put all bolts back,

you have a draw on a circuit will need a mechanic to repair this problem

The guy who said you had three sensors blown probably took your money under false pretences. Sensors don't "blow" unless they get struck by lightning ot something equally unlikely. If that was the case the car wouldn't be starting at all. Once the guy accepted the job of discovering why your car wouldn't start I think it is disgusting that he took your money but didn't cure the problem.

I have never heard of rubbing the battery leads together and I don't think doing that would be at all helpful.

I would take a guess that your car's immobiliser is intermittently not working. The car of a friend had very much the same sort of trouble. The car usually started at home after being stood for a while but once it had been run it was a gamble whether it started again. The dealer said it needed a lot of money spent on it so he eventually scrapped it.
Some of those times when it wouldn't start I was the guy who had to discover why. The engine would crank and there was a spark but no injection in spite of the fuel pump running. I could find nothing wrong with the wiring or anything. It was only by reading the vehicle handbook and studying the wiring diagram and asking a few questions that I realised the immobiliser was faulty. This was my first experience of that type of car.

I believe you need to do the same and discover why your engine doesn't start in a similar way. For an engine to start it has to have fuel, spark, timing, compression and a decent cranking speed so when it doesn't start one or more of those things are missing. You need to discover which and then discover why.. OR you could call the auto locksmith first and ask him to ensure the immobiliser is properly and reliably disarming every time.

Finally, it never hurts to begin by reading the vehicle handbook...

Good luck!

A battery from 07 is still decently new to be that bad, but I would check the alternator first, just get the car running and unhook the positive cable from the battery, if the car dies the alternator is bad.

sounds like a bad connection,possibly the battery cables

I have a 2007 Dodge Charger won't go over 35-40 mph and once you get up to that speed it jumps back and forth and when you start it and put it in gear to go it jumps real hard. My mechanic and a transmission specialist said it was a bad tranny I bought a used tranny and the used one wouldn't even shift into gear so now putting another tranny and another computer system in it. Does anyone know anything else it could be I'm so tired of this vehicle

If the battery is dead,it is a dangerous practice
to jump start it,not recommended I should say

If you can charge it, or take it out and replace it, that
is your best bet.

Someone on your street will have a charger
you can use

Either you have had a new key made and it does not quite fit, or your key is worn, or your ignition tumbler is bad.
In either cases, this vehicle is new enough that your Dodge dealer can assist you in making a new key ect.
Please let me know what you find.

It was a bad connection, replaced the clamps.

You need a new battery.
