Starting problem??

Recommended Posts

I have an 03 ss and it has been having problems starting on the first crank. If i start it on the second time it starts right up. No problems while im driving. I do hear the fuel pump prime but it sounds a little odd. Just replaced the fuel filter and fuel pressure regulator. No gas on vacumm side of FPR. I have no other conclusions but to say that my fuel pump is taking a dump. 94k miles. Also considering cleaning my throttle body. Any suggestions will help, thanks.

I dought it will be the batt though because it has enough power to crank the starter

 

Agreed. Next time you try to start it cold, switch the key on and leave it for five seconds, do that three times to let the fuel pump prime and see if it starts on the first try then. Could be a leaky injector, also you have to leave the vacuum hose off the regulator for around 2-3+ minutes to see if fuel is coming out.
