1998 boxster 986 cranks but won't start

[Hugomcff]

Hello guys!

I have bought a boxster that as been sitting around 5 years.
I rotate the key, all the lights light up. It cranks but wont start.

I have like 3.8bar of fuel pressure. If I put some starter fluid the car fires right up (i have spark). 

It seems like the injectors won't open.

 

Immobilizer seems ok since the car cranks (also removed the module from under the seat and cleaned all up, it was not showing any sign of corrosion).
I can hear the fuel pump working when I jump it. 

Already replaced the fuel pump relay and the ignition switch. 

In the diagnostic tool the car cranks at about 150rpm, is that normal?
Also, im getting a value of -40ºC on IAT (intake air temperature).

Please don’t tell us you tried starting it on t-year-old gas! It sounds like you need to clean the entire fuel system.

 Ofc not.
I have drained the old fuel. Put 20L of fresh gas and changed the fuel filter
