Title sort of says it all.

This is a new development, (riding RIGHT on the heels of a stalling at intersections and idle problem) and I've done nothing new to the car in ages.

167k miles, with brand new distributors/caps, wires & plugs around.... 3000 miles ago?

But yeah - get in it, turn the key, wrrrwrrrwrrrrwrrrrwrrrrr.. nothing. try that again a few times, nothing. Then try one last time (normally 4th or so try), turn key, vroom! fires right up. From there it's smooth sailing for however long I drive it. Until I turn it off again :/

Doesn't seem to have anything to do with temperature (12v mod comes to mind - although that's more an SC300 thing).

Any suggestions? I've been searching on the forums here for the past 4 hours - and everyone else's threads talk about a car that wont turn over at all (normally) - or ones like mine that are never resolved.

Last little nugget of info I can think of is, lights in the car dim lightly when I use turn signals, or window / moonroof motors once it's running - and that's been going on for 50k miles easily. Related?


So my SC brothers and sisters.... ideas?

seems like you covered everything pretty well lol...

just go for the 12v mod my friend you will realize that a lot of other members questions were answered somehow with this mod

Isn't the 12v mod only for SC300 engines?

I thought I read something about if it's done on the SC400 (which is what I have) the extra gas just gets re-routed back into the return line from over pressure or something?

If you've got a bit extra info - fill me in n___n

Double check your water temperature sensor that reports to the ECU.

If it's bad, or the connection bad, it has symptoms like what you have described...
