Failure of the fuel gauge to read correctly causes fuel system errors in the 2000 Chevy Blazer. Electric shorts in the fuel pump and failure of the fuel injection system may cause fuel system problems. A faulty fuel level sensor may cause erratic fuel gauge operation. Gas cap defects lead to illumination of the check engine light, while defective fuel filters cause undue strain on the fuel pump.
A defective anti-lock brake system may cause the ABS warning light to illuminate. Defective relay contacts may also cause intermittent ABS and braking lights illumination. Faulty cabin fuses and a dirty lens lead to failure of the CD player in the 2000 Chevy Blazer. A dirty heating rod and clogging of the coolant coil cause the air conditioner to blow hot air and accumulation of sludge at the core.
A faulty intake manifold gasket causes intake manifold leaks. A broken bottom end crank may cause the 2000 Chevy to lose power and make loud engine noises. A faulty engine motor is a probable cause of the engine dying during startup. It could also lead to tappet noises when the outside temperature is colder.
