    Default Tested Fuel pump ok, timing spot on

    I'm more than a little frazzled!!

    Opened up guts and checked both camshafts on both sides with crankshaft and all my settings were spot on. So I thought maybe I should be able to hear my fuel pump and went and tested. After initially tracking the wrong relay (two similar relays) and getting all excited because at least I've now found problem with open circuit between relay and fuel pump fuse, I discovered the correct fuse and the reason why I don't hear the fuel pump buzzing is because the DME only switches the relay when you turn the engine over with the starter. After forcing the fuel pump relay closed I could hear both the fuel pump and the electronic box fan......

    So now I'm up the creak without a paddle. Any other ideas other than dragging a dealer mechanic to my house ?

    Default Relay not fuse

    Apologies with the mumbling I tracked the wrong relay, found the RIGHT relay and found nothing wroing with the fuel pump or wiring .

    Timing is as set with BMW special tools to lock camshafts and flywheel in TDC.

    I pulled spark plugs and they're wet with fuel which means no firing ??
    But when I pull a plug and insert it into a distributor and turn the engine over, I get spark on the plug. So when will I get a spark and fuel but no explosion ?

    I guess you also had your sparks out? With the bobines?
    Have you put your bobines back on the right sparkplugs?

    Had the same failere with an 318iS.
    Bobine for sparkplug 1 was put on sparkplug 2 etc.

    He wants to start, but it doesn't...
    Sometimes you have the idea that he's firing up, but then it goes dead again.

    Read my other post...

    It sounds to me your sparktiming is wrong, caused by wrongly inserted bobines.

    I meant the ignition coil... Bobine is the word for it in dutch *shame*

    Check if your ignition coils are connected to the right wire.
    And you have the right ignition coil to the right sparkplug.

    Thanks TWISM, that's what I thought so I've just gone and checked. I numbered each ignition coil and three were in the wrong order, I switched them back (cause I wrote numbers on them before I took them out) but still the same result.

    Turning the engine over now I hear a definite difference when I take the foot of the gas, just engine turning over mechanically if gas pedal not depressed, some firing when pressed down.

    Something with the firing but I can't find out what.

    TWISM: What you mean "Check if your ignition coils are connected to the right wire" ? The connectors are all fixed sets aligned in the housing which gets pushed onto the fuel injectors. Maybe I'm thinking I cannot put them in the "wrong way" when it's possible ?

    I just checked ETK and the wiring can't be wrong on the ignitioncoils...

    What have you dismounted further??

    1. removed plugs, ignition coils, cylinder head covers;
    2. Cam shaft covers - two top and one common bottom;
    3. Found broken timing chain guide;
    4. removed lower oil pan;
    5. Found oil pump loose bolts (stretched beyond belief) - replaced oil pump;
    6. Re-assembled in reverse order.

    Checked all sensors as listed in my first post.

    Regards
    Richard
