Hey Matt, I figured I'd just update you here on the car, rather than calling later. I keep forgetting to bring tools home on the weekends, so no compression numbers or anything like that. So, as far as my no crank and no start. When I turn the key to "On", I get life. Headlights, windows, radio, blower motor, etc. all will work. When I turn the key to start, everything shuts off momentarily, until I release the key back to start. There is no clunk/knock/whatever noise you want to call it, from the starter. She isn't trying to engage. However, when I was playing with one of the ignition relays a couple weeks back, I got a change. The one in the fuse box that'd be by your left knee if you are driving. I believe it is called "Ignition Relay 2" in the service manual. I figured out that it was stuck open, then I managed to get it to stick closed. With the stuck closed relay, as soon as the key is put in the ignition, it cranks.
This all happened briefly before I left for vacation, so I haven't had an opportunity (until later today) to explore the new information this has provided me. So what can I tell now? It would appear my starter circuit works. I can clearly get power from the battery to the starter, using only existing wiring. It also appears likely that my ignition switch is good. It does things when I turn the key to different spots, at least. Furthermore, and this is the big one, it looks like if I can figure out what all is supposed to happen when I turn the key, to make the switch in ignition relay 2 close, I should be able to at least get the car to crank.
So things I need to check today:
1. What sends power to that relay, and where does it go from there.
2. Does my fuel pump even work? Haven't heard it prime, as I don't think I've gotten close enough to starting the car to get power to it
3. Am I getting power to my ECU? Am I seeing inputs to it, and outputs from it?
I think if I can answer those questions, I'll be a big step closer to having a running car.
