2004 Prius purchase, had started, now no start

Quick simple question...is your foot firmly on the brake pedal when pressing the start button? When pressing the brake pedal, do the brake lights turn on? If either answer is no, then the car is probably only going to aux mode.

 

IF.....you did not charge the new battery before installing it, you KNOW no such thing.

 

you need mini vci to read the codes.

 

You were able to start it after replacing the fusible link, did your drive it at all? How long did the engine run?

 

I'm not sure what you're stating in this statement. What does "it will not lock into park" mean? When you first start it, it's in park.

Also "transmission seems screwed, clunk and bang". There are no gears in this transaxle, what clunk did you hear? Did it ever go into a Reverse or Drive?

And "I did have it go in and out of hybrid mode", does that mean you let it idle in Ready mode?

How many times were you able to actually start it? (this is very important that you know)

 

Have you checked all connections to make sure they are snug? Any corrosion on any connections?

Usually chasing an intermittent electrical issue may be caused by a loose connection.

Start at the 12v and go from there.

 

Well I'm not sure all the problems this car has, but since you changed the battery, you would need to have changed the small j termianls to regular battery terminals. Did you change them? Are you sure there's a good connection?

But besides the battery problem, you seem to have problems going into drive....like axle related problems. I don't think the clunking is from the Transaxle.

To continue trouble shooting, you would need to get a code reader, then you can read the codes. One popular one is a MINI VCI cable that runs using a laptop computer. That can be purchased on Amazon for about $25.00. Without the code reader, you can't really continue trying to guess at this car.

 

What year and many miles of this purchase?

You mentioned messing with it. Did it start before you messed with it?

What is the HV state of charge on the MFD telling you?

 

2004 purchased at auction. miles not reported yet.

 

I had this on my 2004 after 250K miles and a guy in CA modified the odometer PC board to fix it. It also happened on my 2007 Prius at 190K miles, so I put in a used odometer assembly from LKQ parts for $80 and that fixed it. Toyota admitted that they had a problem but if you did not get it fixed in 9 years you are s.o.l.

There are definitely gears in the transaxle. Watch YouTube for Prius transmission.

Sounds like the transmission is blown. But be aware if you keep "messing" with it it will take its toll on the hybrid battery also and eventually discharge it.
If you have the hybrid battery cover off and seem competent to be in there measure the DC volts across the battery side of the relay and see what the charge level on the hybrid battery is. I would expect to see around 200 volts dc unless its getting really low. Really low hybrid battery no mg2 no start.

In the meantime I think you have a blown trans.
