Hard start
Well my LTX Blazer is acting up. When I go to start it it will crank and not start, sometimes it will act like it hits on a couple cylinders other times it acts like it;s not hitting at all. after 2 to 4 attempts it will start and runs like there is nothing wrong once it does start. just doesnt want to start normal. is this a common symptom of an opti going out? I have scanned it and no codes are present. any thoughts on this would be appreciated.

Well I checked fuel pressure and it is definitely the problem, it,s sporadic, the pump is a delphi under warranty so will be changing it out, but cant get to it till monday. thanks for the input.
