No scanner. Car has 95K miles on it. The engine was starting for a second or two, but not at all now. Been playing with it for a few days now. I've done engine swaps and rebuilds, doing that for years, I'm highly mechanically inclined.

When you turn it on without trying to start, what level does the battery display show? You did verify the throttle plate rotates freely? The reason I ask is any dealer you've lost faith in might not have actually done the job.

If the fault lies in the hybrid vehicle parts, battery, inverter or transaxle, you're covered under the 8 year / 100,000 mile warranty. But the key is getting a good diagnosis.

I would recommend getting a set of the maintenance manuals and in parallel, a scanner. I'm using the Graham Davies Mini-scanner and it reads out the primary error codes from the battery, hybrid and engine ECUs and lets me reset them. For the manuals, you can subscribe to the Toyota technical service (fast but a little pricy) and/or buy them on Ebay or from the Toyota technical service. DO NOT BUY the CDs that show up on Ebay because Toyota does not make them and the quality of one I bought for my wife's Echo was terrible.

The 03 manual comes in two volumes and there is an electrical volume:

• Volume 1 - diagnostics, what the different codes mean
• Volume 2 - illustrated parts and maintenance procedures (MUST HAVE)
• Electrical diagrams - very useful to identify connectors and signals

You're about six hours away from Huntsville so making a house call is impractical unless my wife decides to visit Vicksburg.

OK the battery was replaced recently, but because of these no-starts I ask you to confirm its voltage and integrity of connections. I know you are a car-guy and experienced but I'd like to be able to stop thinking about this as a possibility

Update-- Left the Auxillary battery unplugged last nite. Plugged it back in, engine warning light now off, but still won't start. Funny thing now, is it was showing 3/4 tank fuel yesterday, now showing empty, even after pouring in 5 gallons fuel (it's full now, to the top) so apparently the fuel gauge is wrong, both before and now. Main battery warning symbol still lit up. Is there a service port in the fuel line? I cannot find one.

Hi,
When my 01 dash was lit up with the triangle, engine light, exclamation point and low fuel when there was 7 gal. it was confusing to me to try to narrow it down being a non-trained prius mechanic but with extreme caution I simply removed the HV battery cover, tested the pack, halves and the modules with a voltage meter and got all the confirmation I needed.
DO NOT DO THIS UNLESS YOU ARE EXPERIENCED IN HIGH VOLTAGE ELECTRICITY.
