hey guys, i have a 91 305 tbi firebird. It started a few weeks ago not starting the right way... there was too much fuel flowing through the injectors, but i could unplug the injector and get it to start. last week, however, it went completely out and the injectors are dumping the fuel into the motor , and it won't start at all.... I changed the top of the throttle body, and the computer...
the injector change did nothing and the computer change did nothing..... it seems to me that the injectors aren't getting the Pulse that they usually get ... Any ideas????

By the way , I am getting spark to the plugs.... just a whole lot of gas flowing through the injectors...

 

Make sure you don't have a pinched wire or something somewhere. Check the injector ground wires for a short to ground. That'll make them stay open.

 

Are you making sure the injectors snap in. they should make a snap sound when there in properly. Also check the orings in the injectors mine where bad which made it leak more fuel then it should. but the only thing is my engine got wet and now the injectors are runing to rich. i don't know what it is
