2001 silverdo 5.3 Just replaced both head gaskets due to leak. Now is really hard to start.engine Motor spins over fine it acts like a fuel related problem. New filter did not help and now the service engine light is on. There is a problem with the port for the scan tool it will not connect to the computer. I am out of ideas any suggestions?
The lighter fuse was blown and the scanner showed a code for the cam shaft position sensor. I fixed the problem last night and it cranks and runs great thanks for the advice.
