My vehicle would start and was able to drive about 1/2 mile before I lost engine power. The vehicle would not start until the engine cooled. I paid $338.00 to have a diagnosis on the vehicle and replacing the crankshaft position sensor.
still working to replace crank case position sensor, bolt holding sensor is under sensor, with heat shield making difficult to remove, car runs like new when it does start, hope I can get that sensor out.
Jumped in my car and tried to start it but it would not start. I tried again after a few minutes and it was able to start. Mechanic confirmed the problem at the repair shop.
Had this problem at 80,000 and 201,000 and now again at 215,000. Engine cranks but won't start, especially when warm. Starts after a few attempts. The problem is intermittent but increases in frequency over a couple months until it's constant, and at that point the car periodically stalls. Also, occasionally rides rough with what feels like a loss of power. Replaced the crankshaft position sensor both times previous and it fixed the problem.
