Cranks just fine, O/D light flashes on dash
Imobiliser?or ecu?
Check what the battery reads while starter is running.Or you can turn on the headlights and try to start it to see if the headlights dim or go out.
If so then the battery is too weak or has bad connections at battery or at the engine ground or starter solenoid.
The trans only blocks cranking so we can ignore the overdrive lamp.
when car will not start, (state , what engine you have first)? 2.0L I4 or V6?
the first thing to check is .
is the gas tank above 1/4?
is there spark. on all 4 to 6 spark plugs.
are all fuses good.
does the CEL lamp glow key on, if not the ECU/PCM is dead and there will be no spark or fueling ever. but fuses can blow and disable ECU.

Take your rig.. drive it to a gas station.. fill the tank up with gas.. also fill 2 jugs of gasoline at the same time... put the jugs in the back of it.. now drive as far as you can until the rig runs out of gas.. then, take the two jugs of gas.. pour it all over the rig, inside and out.. now light it a-blaze, then walk to your nearest car dealer and buy a new car..

u need a diagnostic tool to check if there is any error codes and take it from there
Its below the Dashboard, on the left side of your knee. You have to use a torch & locate it from under the Dashboard, Its roughly near to the Clutch Pedal.
Here, it looks like this:

Had the same problem with my Grand Vitara XL7.
It was put on a computer to diagnose problem. Turned out to be a problem in the emmissions. sensor. Reason turned out to be that it is only driven gently and as it is a V6 2.7ltr engine, it needs to be driven with the revs going over 3000 occasionally.
We took it on a drive on a long straight road in 3rd gear only and kept it going none stop with revs going over 3000 for a distance of 5 miles. This cured it.
It was a build up of carbon or something like that, what we did had the effect of clearing it.Blowing out the blockage.
We did not do this lightly, we were advised to do it by the mechanic.He warned us that it might be a bit noisy and said if we did not fancy doing it he would do it for us.
Problem has never come back since.

I have the same year and the exact problem .cranks all day but won't fire up. we tried a little starting fluid and got a couple of pops but .thats's, not the deal the deal is when it goes into immobilizer mode, because our issue all started just because my buddy left the stereo on for like an hour, no big deal so while cranking it over wee just hooked up the charger and juiced up the battery .anyways how do you get it out of the immobilizer mode we tried disconnecting the battery for three hours, checked all the fuses under the hood they were fine so we checked the ones up under the dash on the driver side kick panel those were fine also. so bottom line ECU maybe everywhere we've researched there is no exact method and now it's our main mission to resolve this lame problem. when we get the answer we will post it so all can know this apparent secret method to get it up and running again .it was fine when we parked it it was running weird or anything .so just need the magic fix .stay tuned for the answer today is 6/5/22
