Gutten Tag,

check fuel pressure.

My Volvo engine starts normally and after 3 minutes this beeping comes and doesn't stop and the engine turns off. Oil pressure is OK, water temperature is also OK. Engine starts badly afterwards. Wait 10 minutes and it starts fine and after 3 minutes it beeps again.

Your motor has 2 oil pressure sensor. One goes to the gauge at the helm. The other talks to the ECM. Need to scan the motor but I think the ECM oil sensor might be the issue

My oil pressure switch went out on my 5.0osi motor. Pressure was good as Indicated by the gauge, but the switch down by the filter went bad causing the ecm to think there was no oil pressure. I belive the motor would still run, it just would not go above 2000 RPM or so. It is easy to check as it is just an open or closed switch. Check with VOM for continuity. The one caveat to this is my engine started fine, no rough running. Maybe a fuel pump or plugged fuel regulator? Also make sure the cooling lines to the fuel pump module is plumbed and working as fuel being vaporized in the pump before getting to the injectors would be bad.
