Ok so I am having starting problems on my 940 turbo. Basically I can drive it and then park it and when I go back in to start it again the car won't start it was just rev but not turn over. I've alread replaced the relay in the car. I've also checked the fuses. I am not sure what my next step should be. This mainly happens when its hot out but it will also not start just randomly as well. I've been told that it was the EPU by some people but I am not sure any advice would be great.

 

do you know how to check to see if there are any fault codes? check to see about this and if there are any codes stored.

check/replace:
Radio-Supression Relay, RPM sensor, perhaps even the Power Stage.

you've already checked up on all the fuses? and i presumethe relay you speak of is the fuel injection relay. Try this stuff out first.

 

This is happening to mine as well. I don't have turbo though. my problem has been it'll crank over, but not fire. After a couple of tries, it would fire up. today, it simply would not start. when the tow truck driver came, we gave it a jump from his truck, and the thing fired up immediately. I'm thinking of replacing the coil, cap and rotor. I'm sure the coil is original.
