Hi yes the car will have to be timed again my guess is that it is probally close to being in time as it starts but being off even by a little will cause it to do that
make sure the timing marks on both camshafts are pointing towards each other and the timing mark on the crank lines up with the mark on the timing belt cover that will put it in time you will just have to look out that the pullys dont move when the belt is put on hope that this works for you!

There is a tool sold at most auto parts shops specifically designed to lock the cam shafts in place when replacing the timing belt. It looks like a large H set on it's side when installed. It makes the job much more easy and can all but ensure a proper alignment for the installation of the belt on the cam cogs.

I am having trouble also with a 98 Neon timing belt.I replaced the water pump, and timing belt at 124.000 miles.The old belt was a napa, so I suspect it has been replaced before.I took my time,and replaced the belt making sure both marks (cam,and crank) lined up perfectly.when I removed the old belt, I noticed the timing mark on the crank was two teeth to the right of tdc with the cam aligned.The car had NO uphill power ,thus the reason for changing my belt.I figured it had jumped timing.I lined both marks up , double checked alignment,rotated the motor 4 times (2 full revolutions)turned the cam back to check for any slack in the belt. there was none. reassembled, test drove, runs great, plenty of power, but now setting trouble code:p1390,timing belt off 1 tooth or more ! these motors are zero clearance ,so I wonder how it would even run if a tooth off.being that it runs and drives fine, I am hesitant to pull it down again, I have put roughly 30 miles on the car since, with no problem, except the code/light. I have had one tech say these motors were susposed to be one tooth to the right ! But there are NO updates,or notes added to any service manuaI have seen. Any suggestions? I'm tempted to just drive it. but worried as it's my only transportation.

My suggestion would be to have your cam and crank sensors checked. If you know that the timing belt is perfectly tdc and aren't going to try the mechanic's suggestion, then that's about the only route you have to try to get rid of the code.
