After the fall, the engine did not want to start over, even stop lights no longer worked. Fuses are all ok.

starter dead silent will not crank the engine?
or starter works fast ,engines cranks but will not start the engine, or runs for 10sec or runs longer and stalls
?
the word start alone means zero.
ok?

worse this makes no sense at all???
?starter,relays,fuses, battery, ecu computer." what to does that mean.?
you threw all those parts,? wow if yes.
must be rich no? guessing?
what does fan mean, engine or dash heater blower?

if starter is dead, silent, just clicks or chatters say so
or if starter motor does crank the engine fast say so
and say cranks but does not start.

see ?
the latter failures are 50 fold. (no start)
no cranks are 6 causes
see why telling what going on first makes the job near 10 more easy,. IT DOES>?
stop throwing parts and ask for help before.
only the parts man gets rich.

Sounds like it's not getting any fuel to the engine sounds like you need a fuel filter or your fuel pumps going down

Check all your fuses make sure they're good. This can also come from bad ignition switch or ignition switch going out

simple test to do
apply the hand brake
start the engine --if it idles ok --no engine problem
apply the foot brake --if it stalls ---replace the brake booster
if it runs ok --run the fault codes

Looks like your key needs to. Be coded by a Suzuki dealer

You may have a security system problem (Most likely caused by an ignition lock cylinder fault)

Is your SECURITY light flashing?

If so, do this:

Turn the ignition switch to the START position then release the key, leaving it in the RUN position.
Wait approximately 10 minutes untill the security light stops flashing, then without turning the key off, turn it to the START position again. It should start. If it does, then you should probably replace your ignition lock cylinder. The problem will gradually get worse until this method no longer works.

If the fuses and bulbs are ok, replace the relays.

Hi, if there is an anti- theft system installed in your van, you mght have a faulty computer. I had the same problem and it was due to the anti - theft system. Ihad to replace the computer. If it is the anti- theft system, there would be a tiny red light continueously on in the instrument panel. I hope this helps.

IF EVERYTHING ELSE IS OK, SOUNDS LIKE YOUR IGNITION SWITCH COULD BE GOING BAD.

If you put a 2 element bulb in a single bulb elemet socket you would or could destroy the flasher unit. Especially if it is a electronic flasher try replaceing the flasher but get mechanicl flasher they last longer.
