I have a Volvo s40 2004 and the car has trouble starting if i put the accelorator to the floor it will start but i must continue to rev the engine up and down to get it to stay on once the car gets going it seems to be fine. help please!! thanks
It sounds like the fuel pressure regulator diaphragm is broken, causing fuel to flood the engine when first started, then clear up and run fine.This is a common problem. let the vehicle sit for a few hours , then pulling off the vacuum hose to the regulator. Fuel may dribble out of the hose indicating bad regulator.You can also smell the end of the hose for a raw gas smell.

The best thing is to go to your local Volvo maintenance shop or Volvo experts to find out whats the problem..usually the coomon ones I think is the programs inside its ECU unit..you try this..ask the volvo experts to reset the ECU and lets see..if problem arise then it is no doubt you might need the sensor..hope this help..

. It went like this, turn radio on, when “code” is displayed push and hold “6” while pushing “power & volume” knobs at the same time. Let radio turn off while continuing to hold “6”. Turn radio back on by pushing both “power & volume” knobs at the same time. It worked on 98 V90.
#2 (JAPAN IMPORT)
-I emailed 2 Volvo Dealers and both replied 6666 is the code for all used Volvo imports from Japan, so I switched the ignition key to pos I for over 2.5 hours and "CODE" appeared, then pushed button 6 four times and the Radio swiched On. Problem solved.
#3
-we altered the client access code input protocol by “rebooting” the stereo (turning it off and on using the combined volume/power input) and, at the same time, holding down the “stereo preset 6” button. The stereo then transitioned into the authenticated mode, allowing clients to listen to NPR without proving identity.
