My wife hads trouble starting the car this morning. I tried when I got home it took some time but when I gave it some gas and had kept it cranking for a few extra seconds it started but wanted to die. Kept the idle at 1500-2000 for about 30 seconds then took it for a drive. Drove fine plenty of power and no hesitation. Gas milage has been normal I guess she has not complained. Could this be this similar problem with the fuel pressure regulator or something different.
It take a while to start when cold and one can small gas in the vehicle after it starts
Hard start due to leaking fuel pressure regulator. Misdiagnosed as starter problem.
Cold morning car was turn over then stall. Tried several times same thing happened. Just recently replaced (within last 10K miles) spark plugs, fuel filter, ignition coils, and the idle air control. Also the car was not throwing any codes during this process.
hard starts, have to press gas pedal down to get it to start.
The car would occaisionally stall when coming to a stop. Occaisionally would hesitate when going at a green light. Progressively taking longer to start; first it took half a second longer then it took a second longer than usual (noticeable to all in the car). Check the vacuum hose to the fuel pressure regulator to see if yours is cracked. If it is cracked and you find any fuel in there its the fuel pressure regulator. If there is no fuel, just replace the vaccum line. This is a common issue so you can search the enthusiast forums for details. Misdiagnosed as the fuel filter and changing it did help but did not solve it. Try fixing the vacuum line first as it's a lot cheaper than getting the entire fuel pressure regulator ($230 from Volvo). The entire replacement of the unit involved 1 bold and takes 10 minutes if you have no idea what you are doing.
Same problem. Replaced fuel regulator. problem solved
my2002 Volvo will act like it want to start but it will idle back off it takes about 5 min to get it started. it may be low in oil will that have any thing to do with it.
If you turn the key quickly to start it will fire and then stall. You have to completely turn the key off and then try again to start the S40. On the second try it turns over a long time before it finally starts.
car didn't start at 50 degrees Fahrenheit
tried again and it worked fine
does it time to time when its cold out
Still dealing with this problem, I purchased a used 2001 car in July of 2010.
Hard starts (engine would turn over several times before starting), especially in warmer weather, for 2-3 months. CEL came on. Replaced fuel pressure regulator with aftermarket version from an auto parts store ($120). Easy repair, required only torx screwdriver bits. Noticed cracked plastic on OEM fuel pressure regulator when replaced. No further issues.
hard to start when the car has been sitting on a warm day
Just bought an 04 Volvo S40 LSE. Have the same problem with taking a while to start-up. Brought it to Southwest Auto in Dallas who told me it was the fuel pressure regulator.
On Cold Nights/Mornings, the car would like stall on a startup ignition. It sounds like a low skipping air noise and would fail. Second attempt always fine though.
Other than that I love this car haha
Fpr leaks when I try to start it
Dealership Volvo S40 diagnosed fuel Pressure Regulator. Going to fix it myself.
Hard to start in the morning hours.
