I bought a 2001 a used Volvo S40 and for the first 2 months the car started right up. However, it has began having trouble. Now almost every time I turn the key it takes at least 5-8 seconds for the cars to slowly start. Sometimes I have to try twice. The battery is new. The alternator is new. The temperature can be 10 degrees or 50 degrees, it does not make a difference. The car always starts, but the problems is getting much worse and the time is takes the car to start up is increasing. I don't know much about cars, but it reminds me of my riding lawn mower because on my mower there is a manual choke that you push in after you turn the key. My car sounds like I should be pushing in the choke button in order to get the engine really running. The thing that gets me though is, randomly probably 1 out of every 10 times, it will be fine; and it will be fine it I start the car right back up again. However, if the car sits for an hour or more, the car won't want to start. Any insight would be helpful. -Thanks

I had that prob. 4 a while.

Found a switch that was supposed to be shut to prevent fuel from falling back to the tank was open while car was off. So fuel pump had to crank for 4-5 secs. b4 it got 2 cylinder.

try cleaning the idle air control valve bet that will do the trick

where is this swich located that stop the fuel from running back in the line?

Hello everyone :banana:

It sounds like you have a bad Fuel Pressure Regulator.
