I bought a 2006 Scion TC on offerup for $300. It’s an auto with 200k miles, and it’s in decent shape. We bought it not running, was told it stalled while they were driving and it was left in a parking lot. I do not hear the fuel pump working, but originally it would only crank. I charged the battery on a battery charger overnight, put it back in, no luck. Tried jumping it with a battery pack, no luck, just crank. I removed the starter and took it to autozone, it was tested and was told it works perfectly. I put the starter back in and now it won’t even crank at all. Tried bypassing the starter relay, checked grounds, made sure everything was tight, nothing, not even a crank. There was definitely power going through the starter relay because when i bypassed the relay the wire i used was very warm. Can anybody help? I’m stuck i have no idea what to try now.
