wont start

My 92 Rodeo was running fie .My girlfriend took it to get a new stereo put in it now it wont start .I checked the fuel pump and filter there fine .There's fuel in the injectors but they wont shoot out any fuel.Any suggestions would be greatly appreciated.

Is your car still at the stereo installation shop? It sounds like you are blaming something on the installation, but you are checking the fuel system???? I'm confused.
