Why is my truck not starting properly?
A- The hissing you hear is most likely the fuel pump, the fuel pressure regulator or a vacuum leak, which leads me to believe your problem is based around fuel pressure. When turning the key on, and not even cranking, the fuel pump primes the system for 2-3 seconds. It also keeps a prime when you turn the truck off. Since cycling the key a few times seems to help it start, it makes sense that the fuel pressure is low. Cycling the key builds the pressure up a little more to get it to start. Remember, these engines need at least a 55 PSI fuel pressure to start. If even a few pounds less, they will not respond. Cycling the key adds a little more each time. Two possible resolutions would be having the fuel filter replaced, which may do the trick. It is more likely, however, that the fuel pump is beginning to fail and needs replacement
