I broke a fuel injector and replaced it with one from a 1995 4 cyl chevy cavalair. I tried 2 different injectors and the cylinder and intake manifold fill with gasoline. I cant crank the engine. I checked and all the 4 cyl 2.2. Ltr engines use the same injector. Could I have messed anything in the electrical system that would make the injectors open when I turn on the key. The fuel pupm rums about twice as long as it used to. Could one injector I chaned cause this.

Check them with a noid light when key is turned on and see how long the injectors are staying open.

Then one you replaced could be stuck and leaking off pressure causing it to take a while to build.
