I could use a little help. I am working on replacing the dash circuit board on my 69 with factory tach. The car was running well before I started taking the dash apart. I unplugged the instrument cluster and removed it. Now the car will not start. It turns and starts, but dies as soon as you release the key to run. Does this have anything to do with this removal of the instrument cluster/tac/ resistor? or are they unrelated. Could it be a faulty ignition switch. The car is getting fuel and I had someone turn the key and grounded the distributor coil lead and it is getting plenty of spark while attempting to start?
