Question about 1999 Chevrolet C2500
Have the code, and I understand that the code is regarding the Cam relationship (or timing) to the Crankshaft. The truck's computer reads this via the Cam Position Sensor and the Crankshaft Position Sensor (I'm assuming). If one of those two sensors is bad will I get a different code? I just got the truck, and the dude who had it before obviously did some work to it - K&N cold air setup and MSD ignition - so I'm wondering if he messed around with the distributor (which houses the Cam Position Sensor).
I was thinking of getting a new Cam Sensor at the parts store ($30) since it seems pretty easy to replace.
Yesterday I started screwing around with stuff just for kicks, unplugged and replugged the Cam Sensor, messed around with the ignition, plugging and unplugging, and then trying to figure out how it was all wired. The distributor is tight, but the cap has a bit of play in it and I was twisting it back and forth. Later, when it was time to put the truck away for the night it would not start. I could hear the fuel pump go and it would turn over, but not even try to start. I kept messing around with all the stuff I touched before, and even started to put a meter on things, then after about 1/2 hour of this, she just started up no problem. I'm not sure what I did, if anything, but I was wondering if the play in the Distributor cap could knock the Cam Sensor out of range, and if so, if the Cam Sensor will stop the truck from starting? Any ideas?
That code usually means the distributor was moved and the cam and crank signal sync is off,you mwill need a scanner capable of data display to reset it,it should be near or at 0 degrees,if you do not have access to a scanner your local shop should be more than capable of reseting it.hope this helped

383 is a modified engine...since it's not stock, you need to learn to "read" spark plugs. In reality the # used in any engine is a starting point for experimentation. Begin with factory plug, If too white or too black change heat range 'till you find a # that gives mostly white porcelan with light tan tinge. That will be a good plug to run.

You shouldn't need a spark box because thee coil is located in the dist. cap. You need to run a 12v switched power source to the side of the dist. cap that is marked dist. if it isn't maked it is the term. that is on the front right of the conector pad. the one on the left is for hooking up a tach.
