Civic 91, started as normal. Vehicle left warming up, when we returned 10 minutes later it was shut down. Vehicle will not fire, everything cranks, dash lights up, everything works however no start. Fuses are all good under dash, fuse block by battery. SO ndoes anyone want to take a stab at it. Thanks for any and all input.

 

did you check the alternator ?

 

Check dist. cap and rotor. Check fuel filter and plugs. These would be my first guess...
Take off your oil cap and look inside while someone cranks it over. If you don't see any of the valvetrain moving, stop immediately. Hopefully you haven't bent your valves if your timing belt went.
