car won't start. - 2009 - S60 Topic is solved

If this is a european diesel it will be located at the front of the car someplace.

Hi Jonesg;
The vehicle is 2.0T Gasoline, not diesel.
Best regards

I don't think a scanner will show fuel pressure bcause there is no pressure sensor on your fuel rail and it isn't reported to the ECM,, to me that means it dosn't have a PEM, so you need a fuel pressure gauge to read fuel pressure at the rail.
I suspect a weak pump, reading the fuel pressure will confirm it .

Hi Jonesg;
Yes you are right. The other car i mentioned does not have a fuel pressure sensor either. I was going to remove it and try it, but mine does not have one either. I wondered if it was in a different place.
So, in conclusion, my car does not have both a fuel pressure sensor and a PEM?
Did i understand correctly?
We will do the measurement ourselves. I will buy the product in the link you provided and try it.
Thank you
with best regards
Atilla

My car is the same.
no sensor = no PEM is my understanding.
Fuel pressure is regulated inside the tank but it doesn't send any pressure information to the ECM.
Your fuel pump runs continuously.
PEM equipped systems are switched on and off by fuel pressure .

Hello Friends;

We determined that the fuel pump was fine. The pressure was normal and functional. Afterward, I had to bring in a professional mechanic with an OBD device. However, after the scan, no faults were detected, no incorrect data was found, etc. The mechanic removed the air filter pipe, applied brake pad spray, and started the car. However, the car was blowing air back, and a popping sound was heard. The mechanic said it was a mechanical problem. He said it couldn't be solved here.
He said the engine cover would probably need to be opened and inspected.
I don't know what to do. I disconnected the battery and replaced it with a new one, and this happened to me. I don't understand how this happened. (

"blowng air back, popping."
It has fuel pressure, spark.

maybe crank sensor.

If you have a spare PEM ($35 on eBay)...

Hello dear friends;
Thank you to everyone who commented here and took the time to help.
We started the car last month.
Finally, I called a mechanic, and he tried all the methods you've shared. But he couldn't start it (or maybe it didn't want to ). He said there was a mechanical problem and we needed to take it to the workshop. He said the engine cover would be opened and inspected. He said the cost could be between $2500 and $4000, depending on the situation.

My friend, who knows engines very well, told me the engine was fine and that I shouldn't take the car home. We disconnected the spark plugs and cleaned them one by one.

The next day, before trying to start it one last time, I checked my new battery and realized it was very weak. I charged it, and the next morning, I connected both the new battery and my good car with jumper cables and tried again. I held the starter for about 10-12 seconds. It was a mess )
The car was heavily flooded, and that's why it wouldn't start (

Lets concentrate on the bright side- it works. At this point it is not important what and how it happened. Make sure you change your engine oil after all those starting attempts(it is likely full of fuel). After oil change, take it for a good roadtrip.

Hello Vov585;
Thank you so much for the warning. I drove about 400 km. I just saw your message. I'll order it immediately.
And while we're on the subject:
I'm using MOTUL 8100 ECO-nergy 5w30 oil.
Volvo S60 2009 - 140,000 km. Gasoline.

If you have a different brand suggestion, I'd appreciate it.
Although CASTROL 0w30 is recommended on the engine cover of the vehicle, MOTUL 5w30 is always used here, whether it's an authorized service or a private service.
