car will not start until i let go of key.....it just turns over,once i let go,it starts.is that a bad ing switch?
 
Could be. I'd suspect our old friend, the bulkhead connector, first, or maybe just a bad/ loose/ broke connection at the coil side of the resistor--where the bypass wire hooks in.

If it's a bad switch, there are a couple of ways "around" the problem, without replacing the switch.

1 You can hook a nice big diode to the "start" terminal of the starter relay and run that up to the coil

2 I found out that some later Mopar starter relays have FIVE terminals, one of them does the job of the old "bypass" circuit in the switch
 
Have seen weak spark caused by a loose connection but also had on my '71 a bad ballast resistor that would many times happen to just catch a spark right when you let off the key. Being new to mopar and cars at the time it had me going for a while till my shop teacher told me to jump it and the thing fired right up.
