    Car won't start! Need R3v on this

    So I had a problem with the car idling a bit ago and found the AFM elbow had a tear so I decided to do a little tune up while I waited. I replaced the fuel lines, elbow and spark plugs along with the coolant bleeder screw (mine was stripped) and the water temp sender. Yesterday when I fired her up the idle was really low and if I raised the revs up and let it fall it would stall, so I assumed vacuum leak. Well after I did this a couple times the idle and car started behaving normally. I'm guessing it was just the air in the new fuel lines getting out of the system? But then I noticed this clicking noise and I can't figure out what it could be.



    Please ignore the coolant leaking out, when I was taking the old bleeder screw out I apparently damaged the threads :roll: so gonna have to get a new thermostat housing. But anyway, I just can't figure out what could be causing this clicking noise. Any ideas? It wasn't doing this at all when I parked the car..

    Car is an 1986 325es

    **UPDATE**

    I started the car to demonstrate the clicking to a friend and it just started up perfectly and ran with no clicking.

    I wanted to double check the torque on sparkplugs so I disconnected the battery and then checked each one. Plugged em all back in, reconnected the battery aaaaaand nothing. It doesn't start or ignite at all. I took the plugs out checked the electrode gap, they are all perfect, put em back in yattayatta nothing. Checked for fuel flow, yup perfectly normal. But I cannot get it to start at all.

    Quick update, car sat all night and this morning I tried it again and it started up. Is it possible that a sensor or something is being shorted out by the coolant thats spilling from the bleeder valve? I should have that taken care of early this week but I'm going to check the grounds and sensors as suggested

    ***UPADATE****

    Ok well now this getting ridiculous. I cleaned off the CPS (it had gotten rather wet from the coolant leak at the bleeder valve) and started the car up and it ran FINE. Good throttle response and idle.

    Now I go back out there and try it again and nope, won't start at all. It started up barely and then stalled out. And then I tried again the engine tries now, and the tach moves but it just wont get going. I'm losing it

    It is very hard to diagnose a noise like that from a video, as compared to being beside the car. But my first suspicions would be be the fan rubbing, a valve, or a rod.

      I checked the fan, not rubbing on anything. And I don't know how it could be a rod or valve, they where fine and the only thing I did was change the spark plugs. I just don't see how that could have done anything to the internals of the engine

        Get an automotive stethoscope and look for the source of the noise.

          So i just went to show my friend what I was talking about with the clicking and I started the car up and it was totally fine... I am completely stumped here. It sounds fine no clicking at all... My experience with cars is mechanical issues rarely happen some of the time... Not sure what to do now hahah

            Possible exhaust leak off the manifold... Again hard to tell from a video. Are all the plugs tight?

              All plugs were torqued to 22 ftlb as specified in the bentley so they should be fine

                I went out and double checked the sparkplugs, they were all torqued right. But after I reconnected them and the battery and tried to start the car it wouldn't even start. I have no idea whats going on anymore

                  Guys I really can't figure this out. Any help would be appreciated.

                  I checked the fuel deliver, all good. Spark plugs are good. Connections are good as far as I can tell. I don't know what to do

                        Did you test your cps?

                          No I didn't. Is that crankshaft position sensor? Sorry, don't know the abbreviations. Where is that at?

                            On front of the engine on passenger side next to the crank .. Check the fan pulley area sometimes the plastic cover gets loose and rubs the pulley until it shorts out. Had that happen to me when I picked up my e30

                              Try a new main relay and fuel pump relay. check the grounds too.
