99 chevy silverado not starting right away
This just started yesterday.turn the key and it just turns over.hit the key a second time and it starts right up.if it only sets for a while it starts no problem.I changed the fuel filter with no difference.seems like the fuel pressure lowers.someone told me there is a pressure regulator,but I don't know where it is and do I have to relieve the pressure somehow to change it?there's a pressure sensor on the back side of the manifold but I would think if it were bad my service engine light would come on.there's also a fuel pump relay,could this be bad or would the service light come on for that?thanks for any help.
