I love my Prix but have run into wondering if it will stay running. Sometimes when I start it, will stall in seconds. Will start after repeated tries but getting worse. Starts better when at operating temp but have read possibilities being fuel pressure regulator, crank position sensor and camshaft sensor. Any ideas before I start my problem chase? Thanks...

Check your Idle Air Controller Motor on the throttlebody. Mine was bad, and cleaning it did not help. I ended up changing the part and that fixed the problem.

welcome to the forums, your mass airflow sensor is probably bad. my car did the same thing yours is doing and i relplaced it and it did the fix. if not that id say maybe you can bypass the fuel pump resistor and see if that helps. OR is the idle jumpy? is the TRAC light comming on when its stalls? if so, the crank position sensor may be bad lke you mentioned

When running the motor idles out smooth and don't feel any hesitation when accelerating. I will try the MA-sensor and see where that goes. Thanks for the info.

just unplug it and if it starts and runs better, then MAF is bad
