I am going to tackle this car in sections. The fuel system will get almost completely replaced. I removed the tank drain plug and nothing came out. Not thinking that I was lucky enough for the PO to drain the tank I poked the hole with a zip tie. This broke through the layer of crud in there and let about three gallons of ruined fuel drain out. Because the tank is a double bubble design I am concerned about not being able to inspect the other side. With that and the cheap price of new tanks I am just going to replace it. Since everything else has 155k mile on it I will replace all of it to start fresh. The fuel system I have come up with is overkill by double, but it is actually cost effective like this. I want a surge tank so the Bosch 044 is just an easy candidate.

I have a bead roller that I have never used before. This is my first attempt. I don't think Chip Foose will be calling me to join his team any time soon. Good practice though. I will weld it in tomorrow.

I have replaced most of the fuel system so far. Fuel tank, single Walbro 255, fuel filter, most fuel lines, fuel injectors, and fuel pressure regulator. I left the two fuel hoses under the hood just because they were baked onto the metal lines.
The starter was cranking strong and I had spark, but no starting. Checked the injectors by jumping the dme plug terminals. The injectors and wiring to them was good. Replaced the dme with an eBay unit. Getting closer. It tries to start but dies. Looks like fuel problem.
Going to replace last two fuel hoses under the hood and re-do the filter plumbing. One line might be linked where it bends toward the filter.

Before I got to fuel I had no electrical. Good battery, fuses and relays good, nothing obvious. Read some in here, ignition switch might be it. Pulled the steering wheel cover off. Bingo. Ignition switch was completely corroded. Replaced that and the dash lights up with the key in it. Starter turns over strong.

Congrats on the slow burn fix-up. I’m still going on the one I started about 3 years ago. I also had a son since then!
How’s it currently?
