I have a 2006 Lexus GX 470, that i drove through a street with about 2.5ft of water the other day (there was no other option due to an crazy high tide coming up in downtown Charleston, SC).

This happened about a month ago. Afterwards I made it 500 yards and the car just powered off. While I was calling the tow truck (within 20 minutes), I was able to get it to crank back up. I drove it the next three weeks through Christmas without any issues. On Christmas I parked it and we drove our other car out of town. When I got back, it cranked for maybe 15 seconds, then died, and hasn't cranked since.

When I say it won't crank, all of the interior power and lights come on, but when you turn the key nothing happens. No clicking or anything such as a bad starter would cause.

I have taken it to the repair shop and they can't find the issue, and they tell me their scanner won't talk to my ignition, fuel injection, and I think emissions computer. They can talk to the ABS computer.

Any ideas on what we should be looking for? I am terrified I am being taken by the hour right now and the service manager doesn't sound all that confident.

I know one tell tale sign of a screwed up engine computer is the check engine light failing to illuminate when you turn the key to the "on" position before you start the engine.

What do they mean they can't find it? Did they just shove the truck out and say "sorry"?

It almost sounds like a low voltage issue or connection to the battery.

It's not that they can't "find it". The Techstream scanner and my fuel injection/ignition computers won't "talk".
