360CS RH bank no fire

Fuel pressure in the rail means your immobiliser and crank sensor are ok.

Try swapping the left and right Master Motronic Relays behind the seats. These provide 12volts power to the coils, injectors and cam sensor. Also check fuse 41 (green) as shown below. Fuse numbers and relay numbers may vary from car to car, but the location is the same.

The problem may be more localised than power coming from the relays, but let us know how you go with the relays and fuse.

 

Check the injectors on the RH bank could be a wiring issue, bad connection, or clogged injectors. Swap LH and RH injectors to see if the problem follows. Also, test for spark while you're at it. If injectors are firing, might be a ECU or fuel map glitch.

 

How often do all 4 injectors fail simultaneously?

 

Extremely rare unless there’s a common cause (bad fuel, wiring, or ECU problem). Test one at a time. Keep it simple.

 

yep, that's why I questioned swapping the injectors. There are lots of easier steps first.

 

Exactly injectors are a last-resort move. Start simple: check plugs, coils, fuel pressure, and clean the MAF. Cheaper, easier, and often the real culprit. Save the injector swap headache for if those don’t solve it.
