I have recently replaced the battery and alternator. After letting the vehicle sit for a week it now is hard to start. It takes three tries before the starter turns the engine over. It will only stay engaged for a few seconds then stop as if the battery isn't charged.
It reminds me of a grounding or a starter problem. How can I tell the difference? What else should I check?

Could be either, or could even be a failed starter or other issue!
No magic bullet fix here or "fix" button... you'll need to test the battery first, and once you have it fully charged it should start the car. If it does not, next suspect the starter. Once you have gotten the vehicle started and have driven it for awhile, turn it back off and let it sit for two hours. After two hours, feel the BACK of the ALTERNATOR. If the back of the alternator is hot after two hours, replace the alternator.
not starter or alternator do you have any codes? if you have an electronic odometer ,put key in ignition and turn it on and off 3 times without starting engine, and stop with ignition in the on possion and you will get codes where millage is displayed ,at the end of codes it will say DONE
The battery gives the voltage necessary to start the vehicle, then after it is started the alternator will spin off the accessory belt and recharge the battery for the next startup.If your alternator was bad the vehicle would start but turn off shortly after driving a few miles. After making sure the battery is charge, clean the battery terminals and make sure they're tightly connected to the battery. If the engine doesnt turn over, it may be your starter. The alternator on the Pacificas arent really hard to take off since theyre located on the top,so if you're second guessing its the alternator, then just release the belt tensioner pulley and loosen the alternator bolts and have it tested at your local auto parts store. Good luck
look for the starter(up top sitting over transmission) and have someone hit it (not too hard)with a hammer while key is held in the crank position,if car starts you will have to ck connections at starter ,if ok you need another starter,reman starters of any age are never as good as the originals,just not cost effective to buy brand new,too expensive!
was the voltage checked at the battery! if not, check it at battery. at least 14 volts or 14.2 volts at battery with vehicle running. if it is less, then you may have a bad wire coming from alternator to battery or a bad battery ground. vehicle when engine is off should read at least 13 volts or a bit higher. make sure battery terminals are clean and tight. the cable connecting alternator to battery has a fusable link in it. if the alternator is over charging it will blow the link. also you may have a light or other thing that is not turning off. good-luck! let me know if you fix it ok!!
I find I have a similar problem with my Suzuki Esteem, that I'm trying to fix right now. I'm not an expert, but I believe it could be one of the following...
a) the contacts in the starter motor are worn out, therefore I'm not getting a surge in power that's needed to start the engine.
b) If I let my car sit overnight for twelve hours or so, it has a hard time turning over, the battery could be power-draining overnight (it might need to be replaced). I find it's starts easier when I unplug my accessories from the power adapter before I leave the vehicle.
c) The alternator is not charging the battery properly, which means the engine will have a hard time getting enough juice to turn over.
The first time this problem happened I recharged the battery for 20 minutes. I only ever had to do that once. Often it will start without jumping it if you just hold the key forward until the engine catches (takes about 5 seconds). I know that is a bandaid solution, pretty soon I'll have enough time to actually get find out what's going on.
I hope I may have been able to share some insight, let me know if you found any solution to it. I'll post my solution when I figure it out
This sounds like a ignition control module they are inremittent problems that are difficult to diagnose, I am surprised tha tno code has been stored however, before spending more money try this when the car acts up pull ou a plug and see if the spark is week or not present at all hopefully you will have an assistant present to turn ove rthe car when it happens this is going to eliminate the ignition system as the cause, move on to the fuel pressure, on some cars there is a cold start sensor that causes the fuel injectors to stay open longer upon start up.
