My daughter has a...

My daughter has a 2006 Lexus IS 350 the dash lights up and the start button is green but when you push the button nothing happens. She had taken it to the toyota dealership and they told her the ECU was out and that it would take $2500 to fix it. I had a mechanic take the ECU out and I sent it to be repaired, The mechanic put it back in the battery was low and he jumped it off, it turned over for a minute but then stopped. It hasnt turned over since then. What else could be causing the problem? The locks and lights work, everything works as best I can tell but the engine acts like it isn't getting anything, completely dead. I installed a new battery to make sure that wasn't it but still same situation

Mechanic's Assistant: Have you checked the fuses? The dashboard bulbs?

What fuses should I check in particular?

Mechanic's Assistant: Are you fixing your IS 250 yourself? What have you tried so far?

I just had the ECu repaired

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I can't think of anything

The first thing I would do in your situation is to do a load test on that battery with a proper carbon pile tester, so we can take this out of the equation. Then if necessary continue.

HERE ARE THE POSSIBLE SCENARIOS...1. DEALERSHIP MISDIAGNOSED PROBLEM COMPUTER IS NOT AT FUALT. 2. SCENARIO NO 2. DEALERSHIP WAS CORRECT IN DIAGNOSIS AND IT WAS NOT REPAIRED PROPERLY AND 3.
