ECU 940 turbo

My 940 ran great, after parking and shutting car off, it would not start the next day.
If the ECU is bad, would I still get spark on plugs, 12 volts to rail injectors and EM coils closing, I do have fuel flow at rail.

I would get a tool to see if you have an injector pulse at the injector plug - they are pretty cheap to purchase

Injector pulse

Dead Smith Volvo, If I have no pulse readings on the injectors would that suggest replacing the ECU.

940 no start RSR question

Pulled the Radio Suppression Relay, which pins are for the coil, I want to see if the coil is open (failed), I'am hoping this is my problem, otherwise maybe the ECU.
