My Volvo starts very hard when it is cold in the morning. Have checked fuel press. And volume, vacuum leaks, mass air flow, temp sensor, injector leaks. Am suspecting poss. Cold start valve as my test light does not come on when cranking cold. Am cleaning the intake valves right now. Starts perfectly when warm. Any suggestions? I am, by the way, a former professional tech. If your interested in my help here at the site, please let me know.
