    Won't Start after replacing Fuel Injector

    I just finished replacing a fuel injector and vacuum hose and it won't stay started. I can start it and if I keep reving it, it will stay started but as soon as I stop it starts dying. Also when I am revving it looks like some fuel isn't getting burned up because I have some moisture behind my car and it's smoking. One of the cables on the TB is pinched behind the fuel rail, does that have any effect on my car not starting? Seems like its acting like its not getting enough fuel. Any help would be greatly appreciated!

    I've had replacement fuel injector that were stuck wide open or stuck closed. Eventually after sitting around with fuel in them they loosen up. But if its only one injector like yours, then I think it should still run, just misfire maybe.
    Maybe you now have a really bad vacuum leak from somewhere.

    I had a vacuum leak that is why I replaced the hose and I have no codes, the code for the misfire I had was because of the injector and vacuum leak and I replaced the injector and hose to fix that and I no longer have codes but the car won't start. But would one of the TB cables being pinched cause the car not to stay started? Cause I have one pinched behind the fuel rail. Also what would cause some of the fuel to not be burned up?

    no, a pinched TB cable won't cause your issues. If the car in running really rich for some reason you'll have unburnt fuel. or if there is no spark on a cylinder or 2 you'll also have unburnt fuel.

    The thing is before I replaced the fuel injector and the vacuum hose it started but had the cylinder 6 miss codes, now I don't have the codes but it just won't start. Maybe I'll make sure the vacuum hose is plugged in tight. Also, would a injector connector that is loose cause the car not to start, well to stay started? If I had a miss shouldn't I be throwing codes or a bad spark plug for that matter? I checked the vacuum hoses and they are all connected right, could it be my fuel pump? I just don't want to replace it if it's not.

    now the code p0108 comes up, is the map sensor on the back of the intake or some where else?
