What year and model is your truck? It sounds like the tach signal wire might have been cut/disconnected, or needs to be reprogrammed. Any of these would cause the remote start to crank endlessly, even after it is running causing a severe grinding noise. Do you know the model of remote start, and does it still start with the key okay?

honestly? download the owners and install manual for that unit.

read the T/s section. if you feel over your head, you need to do the SMART thing and find someone else to correct it.
