2001 silverdo 5.3

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?

Check the cig lighter fuse. If it's blown, scanner won't communicate with the ecm. Will it finally start? Have you checked the fuel pressure?

I will check the fuse tonite. I have not checked the fuel pressure yet but that will my next step.

Thanks, for the help

Yes it will start it just take a lot of cranking

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.
