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.

 

Have you checked your fuel pressure?

 

Going to do that in the morning, but it doesnt act fuel related. also no tach movement while cranking with no start. autometer tach not oem.

 

fuel pressure was fine this morning, but its starting good. go figure. I will monitor it through the day and see what happens.

 

Well it's definitely fuel related. pump is slow to build pressure at times and not at other times. going to check voltages and wiring to pump.
