If the cam belt survived, the starter should make a more or less continuous sound. If it ramps up and down (fast, slow, fast, slow) you probably broke the timing belt. However, there's a lot on the forum for changing timing belts. It will need one regardless so do that anyway.
Before doing any more check the following -
Check the ignition coils for rust expanded core laminations. Rust will blow them apart and might be why it wont start.
Check the alternator for cracked casing - rust in the stator core expands seizes the alternator.
Check the sump pan for rust at the front. They commonly fail. Three years is more than enough to mess that up
Check the exhaust for rust. Joints and welds fail first.
Get an endoscope camera into the sills and box sections. It might be rusted out especially at the back near rear swing axle mounts and front bumper crush cans.
Rear axles rust. Scrape off loose rust especially at the spring pans. Treat with chain saw bar oil, thinned with white spirit.
Unless kept pumped up really hard, tyres are likely to be shot and wheels might be rusted at the seams.
Brakes will be rusted up. Front discs almost certainly need replacing. Rear drums might be ok.
