Yeah it's got the glow plugs, but I've waited for those to do their thing and it still does it. Also, it does it hot or cold, glow plugs are only needed when the motor is cold. I'm guessing it's shut off solenoid related.
One thing, I went on trip for a week recently and pulled the ignition relay and the fuel pump relay as an anti theft. Worked fine before I left. Come back home, replace relays and now this nonsense. Likely just coincidental but thought I'd mention it
