Hey guys, I've had my used SRT6 (26K miles) for 3 days now. One thing I notice is if the car has been sitting a long time that it is hard to start the first time I turn the key. It may take a full 3 seconds of starter action before the car finally starts. It seems to sputter right after it does start for a quick second.

If the car was recently driven then it starts right up. At least I think it does, maybe I should pay better attention....

Starter sounds strong, battery says 3/2007 so its not too old. Are injectors a common issue on these cars, or dirty fuel filters? Nothing comes up in searches so I'm guessing not.

Any suggestions will help!

 

Somebody here had that problem and they fixed it with a new fuel check valve

 

Sounds like the check valve in the fuel pump. The whole fuel pump will need to be replaced.

 

Does the fuel tank need dropped to get to the fuel pump on a srt6? on my last car all you had to do was lift up the bottom of the rear seat, remove a few screws and there it was, super easy.

 

Nope, you can get to it through the back hatch area.

 

That is good to know, thanks.

 

Thanks guys. My first suspicious was something with fuel delivery, or maybe air delivery. I'll live with it for now... Let me know any other suggestions.

After spending time taking in the srt6's driving experience, these little quirks seem well worth figuring out and fixing.

 

Try this:
Turn the key to on only & wait for the fuel pump to cycle off. You should be able to hear this in a quiet area! Key off. Go thru this cyle 2 or mabey 3 times to build up fuel if you have a lazy pump or inards.
If this works on a every time bases that you have to use it after the car sits overnight you know there's either bleed down of pressure or a weak pump on initial start up. Getting your pressure chk'd with a gauge will either eliminate or confirm a weak pump & point you in the direction of a weak fuel pressure regulator.

Aaaah, great idea. I'll try that today.

 

Guys I'm wondering, do we use the same fuel pump as the SLK320 or are our cars different once you leave the engine/tranny area...

 

I put in 91 octane last night as the original tank of gas from the dealer was almost empty. Obviously a dealer would put in 87 octane to save money, I always figured that, but its ok since its only 5 days running on it.

So this morning when I started up with my new 91 I swear it started much better, and maybe didn't lug as much, if at all. Who knows? I might be dreaming, and I won't know until later today when I leave work and then tomorrow morning when I leave the house again.

But does it make sense to you guys that a car may start hard and lug lug lug for 2-3 seconds if had too low of octane?

Or am I suffering from wishful thinking....
