Q: 05 acura tl wont crank till the third time trying?

If the problem occurred right after the service, there might be a connection. If the timing belt were not correct I would expect to see a check engine light, so that’s probably not the case. But there might be a vacuum line off or a loose connection at an air boot that is causing the problem. If the problem developed later, it may be unrelated. On high mileage cars like yours I usually suspect one or more injectors is dripping when the car is shut off, causing an over-rich condition when you try to restart. Either way, you can contact Your Mechanic to have a technician come to your home or office to check out your hard starting Acura and let you know what can be done for it.
