2018 Honda Accord won’t start after back end repair

My 2018 Honda had an accident and we had to cut the the back and replaced with a new back but since we finished the engine won’t start what can I do to make it start

My crystal ball says… we dont have enough info to answer that.

If it was hit hard enough that it required cutting and welding,

My guess is the fuel pump cutoff switch has also been tripped.

What do you mean by “won’t start”? Do you hear that rrr rrr rrr sound w/the key in start?

My Magic 8 ball says… take it back to the place that did the work and ask them.

This is not hard.
