Wont start. Plugs are dry. Disconnected one of the fuel lines and cranked and fuel shot out, so the pump is working.
Any reason why the injectors all of a sudden would stop working?
How can I check if the injectors are working?

 

You might have a clog in your fuel line...

 

It worked fine yesterday. Today, nothing.

 

That's very odd. I'd check the fuel sock, replace the fuel filter, possibly remove the fuel rails and clean them out. You're getting spark? How old are your injectors? Do you think it is time to get them cleaned and rebuilt??

 

put a screwdriver end at the injector and the other end at you ear have someone crank the car and listen for a tapping sound to know if they are pulsing but also check the basic stuff like the sock, fuel filter, fuelines. You can also disconnect the return line under the hood point it in a cup and have someone crank the car to see if fuel is running through the rail.
