Re: car won't start. - 2009 - S60

Merhaba 1. Check your timming marks and verify they are good. 2. There is some whistling sound when you turning the engine which throws me off a little, but let's ignore it for now. 3. The car was not "staring good" for a long time...please elaborate further after what event it started, or...

You need 3 bar fuel pressure for the car to run do I think this is finding your problem. Can you get the car in a quiet place so you can listen for the fuel pump on key turning in, without starting?

I think you can swap PEM without issues. ECM will not work from one car to another. If you suspect that your problem is related to the lack of fuel- buy a bottle of "easy start" or "brake cleaner" and give a couple sprays into intake manifold prior to maf sensor or spray while cr...

my $15 elm 327 code reader for smartphone can read your fuel pressure and pump duty cycle.

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 co...

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 .

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.
