When the Check Engine Light ( CEL ) is showing, an error has been detected in the engine management or emission system. You would need to retrieve the trouble code as indicated by the CEL.
Autozone provides the scanning services free. Get it checked and let me know the exact trouble code, it would anable us to understand if the speedometer not functioning is related to it.
Yes, the fuel sending unit is located in the fuel tank and since it is not the cause of the sending unit, the next thing that you should check woule be the gauge and its wiring circuit. It could be loose connections behind the meter cluster, a faulty gauge or a p[oor ground connection.
