I've owned my 2005 Crossfire Roadster for a few years now and never had any problems, until a few months ago. I got in to go to work, and the thing would not start. It just cranked, but no fire. The next day, it started right up. I bought a Innova Diagnostic code reader and it gave the code for a crankshaft sensor. Installed the sensor, and it worked fine for a week. Then the same thing happened, but the check engine light came on, (crank but no start). The code was again crankshaft sensor. After reading this forum, I bought a camshaft sensor and put it on. Worked fine for another week. Same thing. Crank over, but did not start. Thinking that maybe one of these sensors was no good, I replaced BOTH of these sensors again. It started fine for another week until the same thing! The code reader showed crankshaft sensor again, but every time I erased the code, it comes right back on! Right now the car runs fine until I get on it. If I really get on the gas, it stalls, the check engine light comes on, and the code reader says "crankshaft sensor". I replaced both of these sensors for the third time, and it still does the same thing??? I am at a total loss.... Anyone have any ideas?
