What would cause my truck to turnover repeatedly before starting? I replaced the fuel filter, and a cracked fuel line coming off the fuel rail on the driver side. Is it possible that the pcv valve would have anything to do with this issue?

 

No. Did this problem start after you changed the filter or was the condition there prior to the filter swap?

 

Turn the key on and wait a few seconds then do it again and then try to start the truck. If it starts like normal then you are losing fuel rail pressure. Causes may be a fuel pump going bad, fuel pressure valve on rail or a small leak. I have three Silverados and have replaced the pump on two with a good brand ( no chinese crap) and it has solve my starting problems
