WK1 Troubleshooting / Problems Discussion / Dealer ServiceIf you are having some problems with your Jeep Grand Cherokee SRT8 and need assistance in troubleshooting and diagnosing the problem, this is the proper place to discuss it. Were you treated fairly or poorly at a dealer? Warranty issues? Let us know.
could be a number of things. first place to start is the battery, you wont be able to test it yourself without a load-tester, take it to a parts store and they can check it there. next you could have dirty spark plugs, if the battery is fine, check a few of them. if that doesnt work, check the fuel filter, you could not be getting adequate pressure right away from restriction in it, it takes a few seconds to build up. then if that doesnt work, maybe you might have a tiny leak in the fuel rail, that would also take a few seconds for the air to purge out (doubt thats the issue though or youd smell fuel all the time )
hope this helps

Went to advanced and they said battery has a clean bill of health and i dont smell anything but the mopar fart when i get on it good so if it does it anymore ill see whats going on with the plugs. shouldnt be do im only at 50k miles
Could be the cam position sensor. If it's going it'll take longer for the computer to know where the cam is and start. Sensor is around $20 and takes only a few minutes to replace. It's on the left side of the timing cover.
I get this same problem too. Usually takes 1-3 clicks and I'm up and running, othertimes it take a solid 2-3 seconds.
In my case, it happens a little bit more often when it's cold out. It definitely happens when I don't drive the rig for a couple days. I left town for a week and it took about 10 minutes to start. The longer it sits, the longer it takes to wake up.
I just assumed that cold starts may take a big longer. What I don't get is why when I leave for 2 days, it takes a few tries to get 'er up and running. When I'm gone for a week, it takes 10 minutes to start. It wasn't cold out either, actually about 80*f
Yeah it's cold mode, it shuts down cylinders and alternates between them to make them all work harder thus generates more heat, that's where the rough feeling run comes from. Also turns up the idle speed while doing that. Just wanted tonshed somelight on this for everyone, it is ok for your engine. The concept came from keeping heat in diesel engines , I was surprised when it was on something this small actually lol
