yes sorry, one thousand ohms.

i think i fixed the problem, I feel kind of silly.

I believe what happened was that my first ignition coil was legitimately bad. I replaced with a spare coil from a 400E which was only installable if the wires were bent in a funny way since the terminals were on the opposite side. I must not have tightened one of the wires properly causing the screws to loosen over a period of driving for 2 weeks.

I ran a bunch of ignition system tests on the car and they all checked out. I finally came to the conclusion that the wires to the ignition coil were bad. I had someone start the car for me while I jiggled all the wires and finally the car started. I loosened up all the bolts, reorganized the wires and retorqued them. Now the car starts fine and seems to run alright.
