    Look at underside of fuse-box cover in engine compartment. There are two, EFI1 and EFI2.

    I took efi2 out and replace it with the fog fuse just to test it. Still nothing. I change the fuel pump out as well. Could a clogged fuel filter cause this? I dunno

    are the plugs firing?

    after a few cranks, if you pull the plugs are they covered in fuel?

    Spray some starting fluid in and see what happens. If it starts with the fluid you have a fuel issue

    Check your fuel pressure.

    Open data link connect 1 located in the engine compartment above and next to your turbo downpipe (small black rectangle box) using a electrical wire or SST, connect terminals B+ and FP, turn the ignition switch On but do not start you should able to hear the fuel pump running, if not then your fuel pump has no power.

    Sounds like ECU or fuel ECU to me.

    I had this same issue and it ended up being a fuse blown in the wiring to my fuel pumps. My car was fine after a long drive. Went to start it in the driveway and it just kept turning over like your video. My suspicion is that your car is not getting fuel. Whether that's from the pump itself or the wiring related.


    - Check the ECU for loose wires/ make sure everything is plugged in.
    - Check EFI Fuse
    - Check fuel pressure
    - Check fuel: fuel pressure/ fuel pumps/ fuel pump wiring.

    I could be wrong: But I'm not sure that the fuel filter would cause a sudden issue/ no start. You would likely notice a bad fuel filter gradually over time.

    Went to change plugs and noticed these two harnesses unplugged. Where does this go?

    Picture not showing up I guess but I do have an update. After changing the plugs it started right up?! God I feel stupid. So after changing the fuel pump and spark plugs I took it for a spin and it idles a little low when at a stop and sometimes shuts off?

    Don’t mind the license plate rattling. Gotta fix that

    Just wanna thank everyone who replied and was helping me out. I appreciate it! Glad there’s still people out there, since the forums ain’t what it used to be.
