Hi, I am not sure if you can help me or not but I have to try. I just replaced my engine in my Subaru Justy GL 1990 fuel injection and 4 wd with a engine from a junk yard. Now that we have it in it seems to not be getting any fuel. I tries to start but acts like there is no gas. Do you know what it could be or what we can do? God bless, AnnMarie
