yep exactly right. so to catch it on first turn of key you would need to be probing during the fuel pump prime, or you can probe it while car is cranking on starter. or if you swap the relay as above you can probe the injectors with ignition on (and fuel pump will also be running at the same time)
Happy days, the car now runs again. 12v injector feed checked out fine exactly as RJ explains above, I also had a big air leak from an inlet manifold vac port blank that had split that was causing the car not to idle once started up
