Chrysler Repair: 2002 Dodge Grand Caravan, dodge grand caravan, grand caravan

Question
My 2002 Dodge Grand Caravan was having problems on and off in that it would not start immediately.  Usually but the third try, it would.  When it was taking 10+ tries, we had a dealer look at it.  They replaced the ignition coil pack saying this is what the engine code indicated.
About a week later, I had the same problem.  Took it in - they found nothing wrong -returned it.  Upon getting it back, I noted no antifreeze in the vehicle.  I filled it and the car starts fine; however, I have to keep adding antifreeze to keep the level up.  The other thing I notice is an odd smell in the vehicle in the morning - it's not a gas smell but an engine-type oil smell.  Not really sweet or pleasant.  Your input will be much appreciated - thank you.

Answer
describe the no start to me more  are u getting any clicks   or fast clicks  or not a thing at all when u try and turn it over? As for the smell i would say u have a leak  the water pumps like to leak on your van if u smell it coming out of the vents in the AM  that could also lead to a leaking heater core to which the dash would need to be removed and it replaced.If u live near Atlanta I can look and address all of the above for less then a dealer would charge.
