no power after changing the battery

They are all good. We did check those.

And for that a dealer needs to test it?

If the battery is strong enough to crank the engine, I would look at what might have been knocked loose when the battery was changed. Look at the connections for the main coil/distributor lead or fuel supply line connection.

We put it on a scanner a friend had and it says something about not enough voltage to the fuel pump....so not sure what is going on. Pulls codes P1682 and P0230. The next step i am thinking is just to take it to a shop and hope it wont cost a bunch to get it runnin.
