So a couple months ago I had an accident (picture for
reference of the damage) and during the initial repair I had
the mechanic replace the battery, battery fuse, computer,
radiator, and the break sensor. Now just a small note
during the repairs my car was able to start twice once
after the computer was replaced witch I was present to
witness and again after the mechanic contacted me
stating the the battery he bought (second hand) was
working perfectly in the car then a week or so later when I
was checking on the progress of the car it just wouldn't
start any help given would be greatly appreciated

Is it a crank no start or a no crank situation when the problem occurs?

That hard of a hit and there's bound to be wiring harness damage in that area. Its right next to ipdm.

Ok so I'm not gonna pretend that I know alot about cars but I think that's the fusebox right? So should I check the harness for any broken wires and replace it?

Also remember I said the car started once I replaced the computer but then just wouldn't a few weeks later

An IPDM is a 'smart' fusebox, it has a chip inside it that looking at wiring will not address at all. Any harness shorting could easily fault that chip in innumerable ways. The chip communicates with the ECM and BCM as well.

Ok will look into this that would explain why it started before but won't now
