I have only had the 764 turbo versions of the 700's, so the Regina is new to me, and I'm getting no current (checked at the pink wire at the fuel inlet) to the fuel pump with an overnight (parked running fine, next day no start) problem. The only code thrown is the 3-2-1 on the fuel injection side, 1-1-1 on the ignition side, and I replaced the CPS just as an offering to the Volvo gods. So I'm checking to see if there is another relay besides the pair hanging off the coolant reservoir (both good). I've heard that the 3-2-1 code is an upgrade to keep the cold start injector from running when there is no fuel present, so I could ignore it. Plugs are dry with repeated attempts, cranks fine, and everything else is working. Just no start/run.
