I have a 1996 Subaru Legacy that I cannot start. It turns over but is apparently misfiring and when it did start it would idle rough, accelerate once and then suddenly die. I replaced the MAF sensor but the housing tube is not all the way connected to the box dye to bolts being missing. I replaced the spark plugs and it idled smooth for a bit then died. It seems like it could not be getting enough fuel or any at all through the injectors which I thought of replacing. I do not know anything about cars and not even what to ask. I can get parts off of other Subarus in the lot so if someone knows what this may be any advice is appreciated. It won't even start now. Thanks
