If the starter motor engages and tries to spin the engine over but doesn't have enough power to, that could be a severely hydrolocked engine which could be due to a head gasket, but in that case the tech should pull the spark plugs to release the load from the engine and try again. The starter should then spin the engine over without struggling and spray liquid all over from the open spark plug holes.


Just based on the information provided so far, you may want to get a second opinion after towing the truck to another shop that a friend or co-worker trusts.

Thank you for your reply! When I crank the car with the hood up I see something in the middle spinning. It makes the juh juh juh noise like it does usually when cranking but never completes. I’m not sure if that’s what you mean but I hope that helps.
