Lets check fuel pressure. Go to parts store and rent a fuel pressure gauge and see if you are getting pressure.

I was leaning towards a crank sensor. You usually lose injector pulse and spark when a crank sensor goes out. If your getting spark then it should have ran when you sprayed the intake with starter fluid. im wondering if your timing is now off.

I would be surprised really if your timing chain had broken. Your dash stays on when key removed? does the dash go out after you open a door?
