i just put a new motor in my car last week. on the maiden voyage i stopped at a stop sign and the car died...damn. try to start it and nothing no clicking from the starter notta. all the dash lights work and the stereo, i can roll the windows up etc. so i got her towed home. first thing i check is the battery and it is fully charged, next the starter idk why it wouldnt effect a 5 speed full power. i have power at the ignition switch, the main relay and even the coil...any advice? i am thinking ecu
