Hello all,
So I am stumped! Randomly, on Tuesday while I went back to my 1998 LX470 after it sat for an hour I got a crank and no start. I held the key for probably five-eight seconds, it just didn’t fire up. Second turn of the key, started right up. Once on, no misfires, no CEL, no issue.
I was able to consistently recreate this by letting it sit for 30 minutes - 1.5 hours ish after a drive to full temp. So when the coolant temp is still >100. Crank no start, second try it comes right to life. There is no security light on when this happens by the way.
I cleaned the throttle body, and had the battery checked and it was good. Still no help. Intake air temp isn’t off, coolant temp isn’t off. Any ideas? I found a post saying bad EFI main relay, but that’s more expensive than I’d like to just throw it at it. Crank or Cam position sensors? The fact that it only happens when its been sitting after a drive is odd to me, and I don't want to throw parts at it and waste money.
