INGINE DOESn't START P1683 - 2003 Dodge Caravan

Depends on what are you hearing when you try to start. Does the Engine sound like it is trying to start, does the starter even spin? or when you turn the key you hear 1 click but all the lights and everything comes on? If you hear multiple clicks and your lights are dim, that means your battery is done. There are a few things you can check before spending a lot of money. First check to see if your battery is good, 2 check the battery terminals to make sure they are tight, 3 check the condition of the battery cables if they are old or rusty, try to replace them with new ones, they cost 8-10 bucks. 4 try to replace the starter relay in the engine fuse box, this costs 12 dollars usually. if none of these are the issue, then its either you starter solenoid or the starter motor has gone bad. I suggest instead of replacing the solenoid, replace the whole motor which comes with the solenoid.
