I am have a problem very much like the rest of you 1993 GMC truck owners I was wondering if anyone has changed the crankshaft position sensor

I had a GMC Sierra same thing happened bought the part to replace but truck was sitting at my brothers house and he sold it for 300$ I talked to the guy that bought it and he said that's all he replaced and she fired up and has been great ever since thin

Thanks Michael I was about to change the position sensor when a fellow car guy said it was the sensor that controls the temp. for starting . he said it was stuck in -40 mode so we went to Napa and bought the part for 40.00 and it fired right up , and has been running better than it has for a long time , it was getting a little cranky starting some times I just thought the injectors were in need of cleaning or changing but it had nothing to do with them .Thanks for your input Happy Trucking
