2007 Yaris engine won't turn on

[Judah]

Hello all. I have a 2007 Toyota Yaris. I recently went to my mechanic received an oil change, replaced the windshield wipers, and got a new battery installed. After the battery was installed the mechanic told me to turn on the car and everything was fine (He installed the battery at my house). Later in the day I tried to turn my car on the engine would not fully turn on (the headlight can turn on and all the electrical aspects of the car works). Its not the starter nor the alternator the engine just won't fully start, like it gets close but no cigar. The mechanic came back and looked at it and couldn't really figure out the issue. He said it could probably be the compressor (which one idk he just said compressor). He said my best bet will be to tow the car to a shop and test the compressor and any other issue that could be causing a problem. I just don't understand because before the battery was installed the car was fine to the degree of needing a new batter and oil change. Any ideas of what the issue might be?

sounds like you got a crap battery from a shady person. there is no compressor involved with starting. battery, wires, start relay, starter, starter gear, clutch wheel/torque converter,

all new batteries come with a warranty. at least 1 year. most 3-6 years. some 10+

Hello SirDigby. To be fair and honest my mechanic is not just the best mechanic I ever came across but a generally nice person. To the point where he would come to my house to inspect the car and go above and beyond to get it fixed. The car's electronics works perfectly fine (headlights, etc) and just to see if it was the battery I bought a new battery and tried it but the same issue happened. So that told me it was not the battery.
