Wondering if my ECU was fried.
Or maybe just the fusible link?
I had just finished replacing my CV axle and wheel bearings on the passenger side.
Separately, because I had to get a new battery from Costco and it was then perpetually on back order I was short a battery for this.
So, I decided to use a spare battery we have for our Lexus sedan, and it turns out the freaking terminals are reversed, causing me to put them on that way. I feel like a total moron, not realizing positive a negative terminals are not Universal. When I put the negative on (what turned out to be the batteries positive terminal), I found it strange that it was sizzling a bit more than the usual spark you get. My temporary battery was weak at around 10.5 volts to begin with and I’m hoping it reduced potential harm. That, and the fact I never turned it on may have limited the mess. since only then did I realize the mistake I made. So all told, I think I had them reversed for about a minute before disconnecting.
I ended up putting a correct interstate 27F battery on and waited a bit. The ECU never turned on. I let her run for around 15 minutes before putting it into gear. I pulled out of the driveway and got no acceleration whatsoever— only idling speed. I was able to put her back into reverse and back into the driveway where she sits now.
In my initial research suggests it could be the fusible link. I looked at the 80 amp fuse and it is intact. However, I may be looking at the wrong one.
As far as what is working:
ECU is not turning on at all.
Radio does not turn on at all.
Power locks, power, windows, power, mirror, blinkers, hazard, all work fine
Now I’m worried silly that I blew my ECU but hoping that it’s just a fuse or the link.
As far as acceleration goes, I get a small 200 RPM bump when I hit the pedal. Even flooring it gets only that much.
I’m praying the ECU isn’t fried.
I would greatly appreciate any suggestions get her back up and running.
