I have been dealing with start up issues lately. First my starter went bad, i replaced it and everything was gravy. Now about every other cold start, it turns over fine but it does not catch. it seems like a fuel problem. In order to get it to catch, I have to give it gas as im turning the key. As soon as it fires up, it is fine. i replaced one of the relays and i just discovered there is a second one. does this sound like a problem with the relay, fuel pump or what?
