Q: Tahoe lost all engine power while driving, won't start.

asked by on

My Tahoe stopped running while driving home last night, the engine lost all power and will no longer start. It tries to crank but will not turn over. Fuel pump sounds to be engaging when in accessory mode. No codes came up on the code reader but the engine light has been on. Oil and fluids, battery and everything is fine.

My car has 238000 miles.
My car has an automatic transmission.

Hi There, Generally, the check engine light comes on when something fairly serious is going on with the vehicle. This can happen for many different reasons such as a faulty mass air flow sensor, a faulty O2 sensor, a bad catalytic converter, bad spark plugs or wires and many other reasons. Due to the wide range of possibilities for the check engine light to come on, the best and most efficient way to narrow down the scope of what may be causing this is to have the vehicle hooked up to a scanning tool to download any potential fault codes that may have registered in the computer. This will allow a mechanic to determine more specifically what to look for in diagnosing your vehicle. I would recommend having an expert from YourMechanic come to your location to take a look at your vehicle to determine what may be causing your check engine light to come on.
