Assuming the key wasn't moved to "off" (and it wasn't, right?), there are quite a few things that could stop the engine from running. If the alternator is bad, then a dead battery would cause the engine to stop firing, as would a stoppage of flow of gas (empty tank or blockage in line), the sparkplugs not firing, the air filter being to dirty to allow enough air into the engine... If you provide more information, we would be able to answer the question with more specificity.
Yes, they were identical
A dodge charger would run faster because of its motor and depends on how it was designed.
Your local Dodge dealer would be a good place to start...
How much would it cost to repair a charcoal canister on a 2006 dodge charger
2012.
It would probably damage it
If it is installed incorrectly and causes the starter to be engaged continuously/always running it would kill the starter fairly quickly.
It would depend on what the problem is. All throttle problems can lead to a non running engine.
There are many locations to buy a Dodge Charger. One the best places to look is at Dodge dealership. The car can also be found on eBay and Craigslist for a used version.
about 100$ aweek
A charger has more HP and more preformance with a bigger engine the charger would most likely win!
It depends on which version/model year you're inquiring about. The original Dodge Charger could be considered an 'old' car - but it would prefer to be referred to as a classic. :)
