Also, loose or faulty wires or connections can cause hard starting; secure them. Other potential causes include faulty or improperly adjusted throttle controls (adjust or replace them), faulty spark plugs (replace them), low compression (perform a compression test and repair), a weak spark (check ignition system and replace components), or a fuel pump malfunction. Additionally, an overheated engine due to restricted cooling or air circulation, improper fuel quality, a sheare...
