Alternater could be bad. You could be out of gas. One of your fuses might be blown. Here's a question to ask yourself,"Do you punch on the gas often?" That could be another thing. It could be for alot of reasons, but you need to find out more and ask a more detailed question.
loose connection at battery or pcm or ipc bad ignition switch too much crap hanging from key
It could.
your fuel pump can be broken or your fuel injectors...
Could be several reasons, but the first one that comes to my mind is the IAC (Idle Air Control).
Why would my 1984 Dodge pick up truck stall at the light when I stop
Check your fuel filter/ pump. The pump is in the tank.
No...the rim will hit the caliper on the front.
It would bolt in, but will not run. The tone rings for the camshaft and crankshaft position sensors are different.
1996 dodge grand caravan 3.0 transmission fail only in revers
A 2012 Dodge Caravan would have the 3.6L V6. That engine has a timing chain which does not require replacement unless worn.
Do you have a check engine light on? I would consider the idle air control motor to be a likely culprit. You also might listen for the whistling sound of a vacuum system leak.
A Grand Caravan does not have a timing belt.
