    1980 BMW e12 528i crank position sensor ?

    [Hey everyone new to this form but hopfully someone can point me in the right direction my car ran perfectly fine and I pulled the air box and some other stuff out of the way because my dad was gonna teach me how to adjust the valves and I think in the process I knocked the crank sensor loose and I can't find where it pugs back into the harness I've looked all over the engine and can seem to find a loose conector anywhere .... It's a odd looking connector it's round with 3 holes and one solid hole ... I'm confused and frustrated if someone can point me in The right direction it'd be greatly appreciated

    I have to look up your year but most are found by the starter

    Thanks for getting back i got that figured out and it still wont start it just sits here and cranks. its got fuel pressure and spark but it seems to me like the fuel injectors themselves are not spraying like it doesn't give the slightest hint of wanting to start and i checked the relays and they all seem to be working, another thing that seems to be a factor in this is the old maf sensor but this thing was running 3 days ago and the only thing ive done to it was remove the air box and maf sensor for preparing it to do the valves but i needed to move the car this no start problem has occurred
