2006 chevy 2500 express cam sensor code keeps popping up I have replaced the sensor and it still comes on sometimes it will start right up and other times it will keep cranking.
Today I drove it and shut it off went to start it again and it just clicked so i already have a new battery and there was a new starter put on when I replaced the motor 400 miles ago.
Also I tried to jump it and it seems like the starter was really hot I can not figure this out !

I am going to check the relay today I noticed that sometimes when I start it if I let off the key it keeps cranking I will also check the the wires this morning I hope the starter is not burned up it was hit and it was sitting for hours I just tried to start it and it warmed up quick I keep you guys posted thanks

Hi, my 2008 Express 1500 4.3 started acting goofy about a week ago. Cruise control dropped out a couple times, a few weird shifts of the trans, stalling out in gear at a stop or in neutral, but would always start back up. After a couple days of this with no codes, finally, the Check Engine light illuminated. My Torque App showed a current fault P0336 Crankshaft Sensor and a pending fault P0341 Camshaft Sensor. Replaced the Crankshaft Sensor and that fixed it. I know we don't like to just hang new parts on the car, you said the motor was changed 400 miles ago, was it new or used, were these two sensors new or used?

Brand new motor the the van sensor changed twice crank sensor not sure but I am changing battery cables now and go from there keep you guys posted

I just changed all the cables and it wants to crank but barely the starter is super hot and it was new when they changed the motor the battery is new I think the starter went bad so am changing it and see what happens if this don’t fix it I am sending back to mechanic

1 problem fixed the starter was burned up but the cam sensor P0342 keeps coming back replaced the sensor 2 times
