My boxster cranks, but doesn't start. I've change the crankshaft/reference sensor twice and it does the same...The ECM tested good...Please help...What other sensors should I change or what else should I check?

Wish I could help, are you in the OKC area? I'd give Dumont's a call, 1-405-232-6497, and see what they say.

Start with the basics. Are you getting fuel, air, spark? What year and mileage?

Yes, I'm getting fuel, air and spark. She is a 1998 boxster with 113k miles... Last week I was driving down the highway approx 65 mph. I then push down on gas to go faster and all of a sudden it started jerking and popping like I had bad gas or something....I had to pull on the shoulder of the highway because I lost all the power in the car. I tried to start it back, but it would just crank and crank, but not turn over an start......What do you think?

Try disconnecting the plug from the Mass Airflow Sensor then try and start the engine, if she starts right up, replace the sensor. Also try to rent the ODBII SCANNER from Autozone and check for pcodes n post them here and we'll help yah out
