I am working on a volvo that will intermittently have an extended crank before starting. The problem seems to be at it's worst when cold. When the problem occurs I will get a "reduced engine performance" message. Once the engine starts, it runs fine. I have checked fuel pressure and it is within specs and it always comes up even when the problem happens.I have checked for codes and there are none. The problem is getting worse and yesterday, the owner tried to start the car and after an extended cranking session the car started but shut off after the key was released. This occured two times before she gave up.I have not experienced this. I did have my scanner hooked up to the car to check for an rpm signal while the problem happened and it would sometimes show no signal, show a communication error, or show an rpm signal after the engine started. My scanner does not have the european software installed, so I have to use global obd II to access the computer. The battery is new, spark plugs and filters are new, and two coils have been replaced to correct misfire codes. I am at a loss of what to do next.
