The past few months I have been having issues when starting my truck. It takes at least 3 to 5 times of turning over until it finally starts. I have replaced the fuel filter and put Sea Foam in my tank thinking that maybe I had dirty fuel injectors. There were a few times that I had to use Starter fluid to get it to start. My next step is to buy a fuel pressure regulator. Any other suggestion as to what could be causing this? Has anyone else had this issue?
