2008 Hyundai Tiburon turns over but does not start consistently. Now does not start at all. Tried OBD II port and when it will start, I either get P0452 code, else after clearing code, I get 0(zero) codes. However, when it will not start, I cannot get any code(s). Reader claims "NO LINK." Therefore, I cannot diagnose my problem of car turning over just fine, yet failing to run. I won't pay for a tow, but next time it starts, I plan to take it back to the dealer if no help from this site. PLEASE HELP!!! Also, for those with issue of "Christine" shifting down to 1st gear, you need wheel speed or ABS sensor to fix. And anyone who cannot shift automatic into anything but neutral or reverse, the shifter shaft on transmission needs to be removed, greased, and reinstalled and is known to be an issue....especially for those of us who park our cars for the winter. Stuff in there rusts and needs proper lubrication.

Hello, it's almost impossible to figure out what's going on with your vehicle when no one here in this forum can do any hands on diagnostic testing.
I will say that using a diagnostic tool to retrieve trouble codes will only give you a very low percentage of success -- when the vehicle cranks and doesn't start, nothing is being monitored and no sensors or measured components are functional. Once running, any codes that are set can be valuable for diagnostic testing.
A concern where the engine will crank but not start indicates a problem with one or more of a few areas. First, you could have a fuel delivery problem. You could have a lack of ignition spark. Engine timing could be disrupted. Engine compression could be compromised. Proper air intake to the engine could be interrupted or too plentiful. Testing hands on is required to find out what is happening.
The problem was need to replace fuel pump assembly module. Got a PowerUp on eBay for under $65 shipped. Easy installation, lifting up back seat via two buttons and wedging the pump assemby's box to keep seat up. YouTube has videos on how to replace the fuel filter, and they helped me know how to remove and replace the assembly module. Hope this helps ya. My pump was not priming when I turned the key on, which was my indicator that this was my issue. Runs like a top now.
