Where the heck is the distributor for a 2001 Suzuki Vitara?
It might not have one. It might have an electronic ignition coil or coil on plugs. Either way, trace your spark plug wires - the end that’s not on the plugs is either your distributor or coil pack.
If it is a 2.0 then it is coil on plug - so you won’t find a distributor. The odds of all 4 coils dying at once are pretty low. So if you want to look for the one thing that would shut them all down at once it would be the crankshaft position sensor. But very sudden failure there would be a little odd. Have you actually checked for spark? You’ll need a spark tester.
