Well I dont know how this works so im just going to say it. I had a bad injector so I changed it and now it is holding fuel in the valves I have pulled the plugs and dry fired it for about 30 sec. Well then it started but blew gass out of muffler. Well changed injector again and it is still holding gas how can I fix it I really need to know it is killing me I allready know it may be the injectors but there all new so I dont know what or how it is doing it.



Sincerly,
jerry b. Sheppard, jr

Check the fuel pressure could be excessive due to the pressure regulator and clogged fuel return line
