Hello,

It all depends on how the control pressure regulator failed.

It can get stuck with the control pressure stuck high which means low fuel pressure to the fuel distributor and thus a lean condition.

Or the control pressure can get stuck with the control pressure being low which will mean high pressure to the fuel distributor and thus a rich condition.

You really need to use a proper fuel injection pressure tester to monitor the control pressure regulator.

The correct fuel pressure tester will have a ball valve to block the return pressure so you can check "dead head" fuel pressure.
