Why does it keep blowing fuse 34 after changing timing belt? It’ll crank but won’t start, blows fuse every time. Checked marking on timing belt several times.

 

are you saying this only happened after you did the timing belt? I suspect you nicked a wire and its shorting out or a sensor component is drawing too much current. Not sure what's close to where you were working but perhaps its related to the AC system since the pressure sensors are on fuse 34 as well.
