Lewisweller .. my fear is something seized up...the large terminal on the starter (the one that doesnt have battery feed on it) appears to burned and chewed up , similar to a piece of metal exposed that had arching on it
-
JFP in PA ..finally warmed up here in eastern Pennsylvania.. i check the voltage at the battery, the jump terminals and starter ..all the same ... can i jump the starter to test it before taking it off ? Or another way of testing starter before removing it ..i do hve the intake manifold off.
-
Thank tounJFP . Its 8 degrees here today so i will be waiting a couple days for it to warm up
-
Can i check voltage at starter without taking intake manifold off ? batreries are proper voltage amd CCA i am getting a loud click from batrery discharge relay which is at the second battery in cargo area beneath the sub woofer . That battery is new as well.
-
What would cause the voltage drop on the battery cabbles ? my concern is the burning smell i noticed when i was trying to start , could that have been stater burning up ?
-
All fuses good ised scan tool and had a few codes that were generic (probably from pulling fuses) chasis grounds seem ok

Thanks loren. my issue is 2004 cayenne s 8 cylinder wont start . Tried starting last week in the artic cold we were having in pennsylvania ( 5 degrees ) ran for 15 second then died , tried staring a few more times and engine would slowly crank but would not start . Tried starting a few more times and now cranking at all and not even a noise from starter . Did notice a burning electric smell but couldnt tell if from cab or engine area. changed battery under seat , no change . Replaced starter relay in E box , no change checked second battery and have 13.4 volts , but when i try to start i get a loud click from the battery discharge relay next to second battery . i get full power to lights, cab, radio, fan, etc.., how can i test starter without pulling off intake ? Could i jumper at the relay ? could engine have seized ? never had starting issues until this artic cold snap .
-
Loren, you mentioned a second starter relay with the 2 battery cayenne system . Where is that located ? also is there a way to test the battery discharge relay which is connected to the second battery under the sub?
-
I do not have leak down test equipment. Is the fact that each cylinder compression is almost identical to each other a good thing ?
-
Is 120 psi across all 8 cylinders ( 1 or 2 psi variable ) on a cold engine bad ?
-
Checked compression this morning with car cold (65 degrees outside) I had 120 across each cylinder ... compression seems low but I'm getting feedback Because it wasn't a warm engine but the same reading across all 8 is stable.. could my misfiring and unburned fuel be a valve issue at this point.
-
Is there anyway to check each cylinder is getting spark ? Not to familiar with coil.packs, it seems all the gas is not combusting. I have tried a few different plugs and same results
-
It's definitely gas. The engine chugs and sputters while driving. Somewhat loss of power. When I come to a stop or park ,there is a strong gas smell from engine area and there are no.leaks.
-
I agree that it seems more ignition related.. is there some diagnostics I can do to pinpoint the cause ? Cylinders 2,4,6,8 and 3 are the wet plugs
-
Any way to diagnose ?
