Need diagnosis for Saab. Starts/runs fine now but an hour ago, I started it up, within a second, RPM drops and dies. I try again and...— Tamerlane's Thoughts (@TamerlaneBlog) December 9, 2015...it dies again. I can hear whirring sound as it dies (alternator?). 3rd time, I start & press accelerator for a few seconds and it's fine.— Tamerlane's Thoughts (@TamerlaneBlog) December 9, 2015Here are a couple of possible causes:
@TamerlaneBlog On my Previa a similar issue was caused by bad fuel pump resistor.— Uri Halevi (@uhalevi) December 9, 2015@TamerlaneBlog Is this the first its happened? Whirring sound is odd, might need to find the source. First guess is crank position sensor— Bozi Tatarevic (@hoonable) December 9, 2015Do you have any ideas?
