2004-2007 Cadillac CTS-V General Discussion Discussion, Intermittent no crank in Cadillac CTS-V Series Forum - 2004 - 2007; By no crank I mean key in "start" and there's no attempt by the starter to crank the engine over. ...
By no crank I mean key in "start" and there's no attempt by the starter to crank the engine over. No clicking, no security light. Battery voltage looks good during this condition and after. I end up fiddling around by taking the key out, putting it back in, trying again, etc. I'd almost suspect the clutch switch judging by the behavior but is there anything particularly common that causes this? I may take my 2nd key with me and next time this happens try that one, but it doesn't seem Pass-Key related, since there is no security light when it happens.
I'd think a bad CPS would cause a no start, but the engine would crank. Mine just does nothing at all when you try. Then after fiddling around (which may or may not accomplish anything), it cranks just fine and starts like nothing ever happened. As Rich mentioned, this used to happen to him every once in a while (it was his car). There also seems to be extended cranking when cold, but I am almost positive this is completely unrelated.
My vote goes for clutch start switch, you can hear it if you're in a quiet garage when you depress the clutch. If you don't hear a click (starter relay) then most definitely clutch. If you hear a click but no crank, you're looking at the starter.
You may possibly want to check the starter relay fuse also (it's in the main fuse box under the hood), big black fuse. Re-seat it.
The car has been fairly good, with a couple no-cranks here and there. Tonight it did it twice. Once when I was leaving a store, and once when I stopped for gas 10 minutes later. On the latter event, I held the key to start and without doing anything else, it first did nothing, then the starter blipped for a moment, stopped, then it cranked fine and started. I'm still thinking starter because I really don't know how to diagnose it. The question is, do I pay $$ for a new starter now, or wait until it gets worse?
My '05 is at Lindsay right now with this issue. They replaced the theft module and that didn't fix it. Still happens. You depress the clutch, turn the key and nothing, just dash lights and no starter crank at all.
Yes, this happened in the bus line at my kids' grade school. Nothing more frustrating.
Hopefully they'll have some ideas when I head down there tomorrow to get it.
Trouble is, my conventional car wisdom says that starters (or starter solenoids) don't exhibit this failure mode, but if it's broken, it's broken, no matter how "likely." Looks like it's around $200, if GM parts direct is any indication. That's right on the edge of "throw one on and see what happens" cost.
