All right, connect this wire to the white wire just to the left of the oil sensor:
For the time being, remove the black wire with the inline fuse altogether. You don't need it right now. It's confusing things.

That wire with fuse does connect to some sensor down below (head temp sensor?). Isn't that important to keep in place?
I couldn't access that image you provided. Would like to see what you are suggesting with the white wire.

Thanks Phil 
The fused wire from the coil should never be connected to the head temp sensor. I'm sure the fuse is blown now anyway, but take that wire off the car for now. Unplug it from the coil and remove it. You don't need it.
Then, plug the head temp sensor wire into the loose white wire by the oil pressure sensor:

We have ignition!! Started right up with the wire changes you suggested, and a fully charged battery. Rough running at the moment.

The car is running. I have it idling nicely. Kicks out a bit of black smoke when I hit the accelerator. Maybe timing adjustment?
Also, when I put it in gear, it loses some rpm, and when I take foot off the brake and give a little gas, engine bogs down and dies. What to adjust next?
Thanks for all the help. So happy it is running. Just need to tweak now, i hope.

Taking a break now (take the kids mini golfing). I notice that if I remove the short vacuum hose that runs from that little rectangular box that is top center at the rear of the engine, and connects to the air intake of the air cleaner, it runs great under load (in gear and push on gas pedal). If I hook that hose back up, it bogs down under load. Any ideas what is going on here?

Actually, with that short hose attached, it doesn't even idle well. Bogs down. Maybe that inlet on the air cleaner is plugged. I'll check that.

Or the hose, or too much oil in the air cleaner.

Need some more help. Was ready to take it for a test ride, when the pump starting whining. Engine started to slow down and I killed it before it died. Any idea what is going on? It is a new pump. I checked and adjusted fuel pressure last night, to 28 psi. Was running great. I let it sit overnight so the fuel pressure would drop, and then pulled the gauge, and plugged the T back up. I noticed i had added too much motor oil, so I drained to the correct level. I started the car and it idled great. It warmed up for 5 - 10 minutes, and then I checked the ATF and found it nearly empty. I added some (about a quart) and then restarted the engine. It was then that pump began to whine.

Your black smoke symptom and boghing on acceleration are symptoms of running rich.
Once you have done basic checks on the ignition......first (make sure you are burning all the fuel you give it)
.....next make sure you have "0" vacuum leaks. This system reads any leaking vacuum as throttle opening....and gives it extra fuel.
But most importantly....several pages back....you replaced the fuel pump right? And while deciding to do that....you twiddled with the fuel pressure regulator ....remember?
Check your fuel pressure. Ray |

i checked my fuel pressure yesterday. It was running at 33 and I adjusted it to 28. It ran for a good 10 minutes very well. I shit it down for the night. Today, before ever starting it again, the pressure on the gauge read 11 psi. So, i removed the gauge; plugged the T; checked and adjusted oil level; put an additional two gallons of gas in (had about 1 1/2 in already). Then, started it up. It seemed to run great. As it ran for a couple of minutes, I started to hear the hum. Last night, I also cleaned out the oil bath filter, and checked there were no plugs in the hose holes. Plugged fuel filter?

Ok....how did you plumb the pump, what kind of ilter, how clean is your tank, what about the sock filter in the tank? Ray |

I did not check the tank prior to hooking everything up. What i do know is that it was completely empty (hoses had been removed by previous owner, so both fuel tank fittings we unplugged (all gas had been drained)).
I purchased a OEM fuel filter (that white square one). I ran that between the tank and my pump. On the outlet side of pump, inserted a damper and then plumbed right into the hard line in the tunnel.

And, it has run quite well. It idled very nicely, (well enough for me to adjust the timing and fuel pressure. Then all of a sudden, whining from the pump. so, if there was any blockage in the tank or fuel pump, it did not show itself until after it had already run very well.

Having an open and dry gas tank....meaning no gas in it....for long periods.....is a common recipe for scale. The scale iw usually a combination of dust, dirt, dust flakes and old gas additives and varnish. That stuff chips and floats loose when the tank is filled. It plugs the in tank sock filter and starves the pump which is what causes the whining as the pump turbine cavitates and pumps air.
Pull the gas gauge out of its hole. With a flashlight you can see the crud down below. around th tank inlet/outlet tubes.
Remove the inlet/outlet tube assembly, clean out the tank. Personally I get rid of the sock filter and put an external strainer on the line between the tank and main fuel filter. Otherwise when it clogs up you have to drain your fuel and pull out the tubes and sock filter.....possibly in the middle of nowhere. Ray |

Can I clean/pull the sock thingy with the tank still in? Or, better to pull the tank before that work?
Can anything be done in the short term (to get me to a show this weekend)? I do have all day on Saturday to work on this. Feasible to pull the tank; pull out inlet/outlet tubes; remove sock thingy; install in-line strainer?
Thanks
