I've noticed lately that my 940 Turbo starts up fine in the morning (Michigan winter weather). However, if I drive for a while, turn it off and then restart after a short while (say running into the store or something) it turns over quite a bit and doesn't fire up real solidly.

A little while ago, my daughter called and said she couldn't get it started after going into the store. I went over, finally got it started (it acted as though it was flooded) and then started driving home. After a minute or two of driving, it started to lose power and eventually stopped all together.

This seems to be the opposite of what I've seen from other threads I searched where most of the problem occurs when the car is started the first time.

Any ideas?

 

check engine light? any codes?

bad ect?
bad FPR?

wait for the experts to get on...

 

No indicator lights of any kind.

 

No indicator lights on. The ECT is an interesting possibility that I hadn't thought of and when I did get it started once when my daughter had it stalled out it did act more like it was flooded. I can hear the rear fuel pump running when I turn it over so I'm thinking the FP relay is OK.

Update: I did get it running but couldn't get it to full throttle and it sputtered out. When it was running I heard almost a whistling sound. I can hear the fuel pump relay clicking on an off with the ignition turn. I have to take the key out re-insert it to get it to hum again. I always hear it run for a second after turning it over for a while but I wonder if that is the other pump.

I could smell fuel a bit after it stalled out but I'm not sure if it's from stepping on the gas while it was dying out.
