Hi,
I have a 1989 mustang lx 5.0 that wont start. There is no power to the ignition switch or any part of the car. No lights, nothing when turned to accesory. I have doen the following so far:
- Replaced the neg battery cable.
- Replaced the post battery cable.
- Replaced the solenoid on the inside fender (by the battery)
- Fully charged the existing battery and tested with a knwon good fully charged battery.
- Tried to junmp with a 650 amp external starting battery.
- Ran a multimeter between the positive battery terminal and ground.
I parked the car and covered it about a year ago and think I may have done something to disable the vehicle but am not sure. There is a large connector under the dashboard by the base of the steering column which appears to have been previously connected to something but there are no connectors within reach. The connector is yellow and about 3 inches wide with 1 row of connections. Is there soem sort of relay or switch or module that belongs here which I may have pulled out and lost a year ago?
Thanks
