Re: Timing a 1998 Chevy 5.7L K1500

I'll try to explain this as best I can. The CKP and CMP have to be within certain limits. The crank sensor is located in front of the block to detect crank position. The cam sensor is located in the distributor as it is driven by the cam. So, the code you're getting could mean the the dist is off a tooth or 2 one side or the other. If you put the distributor in exactly as the link "MT" gave you it will be close. Timing lights on these cars are a thing of the past. The high end scanners that can get into the "cam retard" or "cam offset" mode puts the VCM into "base timing" mode. In this mode the timing needs to be set at 0 +/- 2 degs. If the dist is in correctly it only takes a small adjustment to get it there. And when your done the plug wires should be coming out of the dist at 90 degs to the front of the motor. Hope this helps.............Steve
