Stalling out agian 93 945 turbo 900

I've seen some relays that didn't respond to the reflowing solder technique-- particularly aftermarket white box ones. You might consider springing for new ones-- they aren't that expensive from places like FCPgroton.com.

One additional suspect on the turbos is the injector ballast pack.

After that, I am running out of "usual suspects". What is your charging system output voltage?

Good luck!

I don't recall what fuel injection system was on that model but there is a fuel pump check valve (next to main pump) on a Bosch system. Check fuel pressure at rail also. Also, how old is the fuel filter?
