Hello,
I have a 2001 Boxster S that left me stranded a few times recently after I had been driving it for a while. So initially it was a crank but no start after getting hot so I thought bad CPS. Then a few days later it refused to start even when cold. I attempted to jump the fuel pump and did not hear any noises so I switched my theory to a bad fuel pump. In the last few days, I have replaced both the fuel pump and the CPS but I'm still getting no start, just cranks away.
I do not smell any fuel so it seems to me like fuel pump is not getting power. I checked fuses and closely inspected the immobilizer, which looked great, but I cleaned the connectors anyway with no change.
I just got a durametric but I'm not seeing any obvious codes. I have seen a message saying the immobilizer is not in a ready state but no clues why so far.
Any suggestions as to how I can identify the cause of this issue more clearly? Any help is much appreciated!
