One problem related to camshaft position sensor has been reported for the 1999 Chevrolet Suburban. The most recently reported issues are listed below.
After I put 55$ worth of gas in the truck it would not start. I waited about 5-10 minutes and it finally started. However,as I was driving,not even 5 miles from the gas station,the vehicle shut off at 45 mph. I pulled over and kept trying to start the truck. It was cranking but would not start. After about 5-10 minutes truck did start right back up. Then,not even another 5 miles the truck shut off again. This time I waited 20 minutes and the truck started right back up. I left it parked for about 5 wks then had the camshaftsensor replaced as well as the fuel pump and the fuel filter replaced,only this time the service engine light was in once these 3 parts were replaced. Service engine light was never on before these issues. Ive had it scanned and it read 5 different codes,including the cam shaft sensor,speed sensors on both left and right side along with 2 more that weren't given to me. Drove it a short distance (7 miles)& it shut of again 55 mph on a busy street. Had the codes cleared and drove it short distances in the last 3 days and today when I pulled up to a redlight it began acting as if it were gonna shut off. I came back home and parked it and dont plan on driving anywhere else until someone can give me an exact answer to the problem and I have it fixed!! I was told by 2 mechanics that they couldnt find an issue!!.
