    Ive got Air, Compression, and Fuel all verified. The car is not currently getting spark still trying to figure that one out. Could be immobilizer, could be ignition relay, could be the fact that I was trying to start it with bonnet open or trying to start it without pushing on the brake.

    Bonnet opening and brake is not going to affect ignition.

    Regarding that loose plug. Can you see any wire colours? I don't have a complete set of wiring diagrams for the right bank, but we might still be able to figure out what that plug does. If one of the wires is violet, it's probably a power wire. Can you check for 12 volts at the mystery plug (key on). Also check for power at fuse PDF16 (bottom end). That will tell you if the RH ECU is energising the RH Motronic relay (which supplies power to the ignitors/injectors & all the sensors, including those devices with violet wires).

    Of course, getting power to the injectors/igniters is still not going to fire up the engine. You still need the crank sensor/cam sensor to figure out timing.


    Are you getting a warning symbol regarding the Immobiliser on the dash?

    Anyway, if I'm reading the Immobiliser wiring diagram correctly, I think if your immobiliser wasn't disabled (in the Motronic ECUs), you wouldn't be able to read engine codes.

    Actually, the top end of fuse PDF16 would be better (use chassis as ground). Also check power at the top of fuse PDF12.

    One of the violet power wires goes to the MAF connector. Maybe you could check for power there on pin 2?

    I'm not sure of the orientation of the connector. Pin 2 may be at the top left or top right?

    I met someone who had the Bosch immobiliser unit dramas on his 430. I think it is somewhat common to delete that all rather than try to recode / replace it and the ignition coil etc? Anyway, good luck and it seems like an amazing deal.

    I think it is a extra plug used in the scud for some sort of selenoid.

    You have fuel pressure, but have you checked that the injectors are working (with, say, a noid light ... if you can get to the injector connectors easily on an F430)

    I checked the power to the top of PDF16 and it has 10 volts on the bottom and top side.
    What does the Motronic relay look like, which slot is it in? Id like to see if the coil and the contacts test ok.
    I cleaned the cam sensors connections on the right side and the left side and the right error code went away and did not come back. The left one comes back with same code.
    I checked the voltage coming into the sensor and the ground and they both seem good. It is reading that Cam sensor B is the one with the fault which is the exhaust sensor.
    When I crank the car i can see the cam sensor angle read in live data but im not sure that really applies to the exhaust side.
    I am not getting the immobilizer symbol. Currently the blue immobilizer box is unplugged.

    thanks for all your help

    Cool ) ... If they help with the diagnositic process.

    You can also just check for 12 volt power at the injectors while waiting for delivery. At least that will help you know if the relays and fuses are working.

    This may be a silly question but can the seats being removed cause a no start?

    Interesting question. I went down quite a rabbit hole looking into this. Did you pull the fuses (near the battery) for the removal of the seats, but pulled the wrong ones?

    Image Unavailable, Please Login

    I was wonding if pulling the ABS fuse might affect fuel/ignition (The ABS calculates vehicle speed which is sent to the Motronic ECU). However, I suspect you'd get lots of messages for that, though.
    Anyway, I see a discrepancy between the Workshop Manual and the wiring diagrams relating to those maxi fuses. I'll have to look more deeply into that.

    The seat belt warning shouldn't stop you starting the car.

    Wiring diagram for ABS power:

    Image Unavailable, Please Login

    Maybe someone has a better diagram than this? @flash32 ?? I don't have a set of diagrams for the seats to compare them. I did discover on the 360 that the wiring diagrams disagreed with the Owner's Handbook. Turned out that the Owner's Handbook was wrong.

    @jdfenn Jeff, when you do get your seats back in, could you possibly confirm that Maxi fuses 7 & 8 do control the seats? Thanks!

    Disregard. The Wiring Diagrams are for the Scud (which has no power seats, AFAIK). The setup on the regular car does use fuses 7 & 8 for seats. I'm not sure why the Scud has extra an extra ABS fuse at the Maxi 8 position.

    Seems oddly low. How is your battery?


    If you have power to the fuse, the relay should be ok. 10 volts though, sounds like a flat battery or you have a high resistance in the power circuit. If your battery is ok, I suppose you could swap out the left and right Motronic relays PSR10 and PDR10 behind the seats.

    "Behind left seat" fuses:

    "Behind right seat" fuses

    If the voltage at the top of fuses PDF16 and its LH counterpart PSF10 are both 10 volts, then you have battery issues.

    checked all these fuses this morning with the seats re-installed. They all show continuity but none of them are showing voltage with the ignition on. Is that normal?

    Charged the battery all night and now 12 and 16 are showing 12.5 volts on top side and bottom side of fuse. Going to check the Motronic relays now.

    checked all these fuses next to the battery and even though they have continuity, they do not have any voltage with the ignition on.

    Checked the power at the injector with ignition on and it measured 8.5 volts. Made sure the battery was still producing 12.6 volts and it is. Does the voltage increase when I crank?

    Scratch that, bad reading, Injectors are at 12 volts as well
