Still no spark, so back to the engine harness. Up to now, I've been using descriptions of the wires and plugs I found online. I linked to them earlier in this thread. The problem is, both of the tutorials I have been using are for the older, "yellow plug" ECU and harness. 1985.5-1989. I have a...

In my quest to figure out why the ignition hasn't been sparking, I've gone back to basics. My first lesson was in getting the starter to engage and crank. I hadn't grounded the engine block, so no circuit. Using the factory service manual available online I looked to see where other grounds...

Swaped ignitor coils. No change. Turning my attention to testing the wire harness. All the wire diagrams I can find seem to be for older 7M engines. I have a "grey plug" harness from late 1989 on, and the online wire diagrams seem to be all for the older "yellow plug" harness. So wire colors...

I go the engine to crank! Stupid mistake, I didn't have the engine block grounded. What an amateur mistake. Oh well, this whole project is a learning experience for me. Engine didn't fire unfortunately. No spark. I have 12 volts at the ignitor and injectors, so at least I got that right.

The Corona brake booster has a leak, and so the brakes don't work. Had to fix that. The problem is brake boosters for a 1973 Toyota Corona Mark II don't exist. Needed a replacement option. Took my chances with a booster from a junkyard MA70 Supra Turbo, and the booster fits! Barely. Didn't...

In these photos, you can really see the effects of time and neglect. The whole engine bay needs to be detailed. I had it so clean all those years ago! The Corona throttle linkage pushed the throttle plate open, and I needed to adapt that to the Supra throttle body. I used a few parts I had...

The wiring that I am doing: This photo shows the B1 connector. This supplies power to the many components. The 7M only needs a few to run. In the middle there are two 12 gauge wires that need power. One is the black/blue (can't be seen in the photo) that just power straight off the ignition...

The thread title cracks up up. 56k? Does anyone have that internet speed still? That's how long ago this saga started. I am pulling these updates from another thread I started on Japanese Nostalgic Car. We will catch up to the future soon. Here is the bolt welded onto the remainder...

Not many updates today. I spent the day pouring over wiring diagrams and searching for the wires I think I need to make this all work. That's slow going! Here is the surge tank all plummed. New starter wire run. The Supra runs the starter signal through the harness. Easy to just keep it...

Needed to get the ECU into a factory-like position, which meant making a new hole in the firewall. I avoid cutting or drilling anything on this car as much as possible, but some is necessiary. A $20 hole saw blade for my drill and a $9 dollar guide bit makes this circle-shaped lack of metal...

Many wires. Such harness. Wow. I have no idea what I'm doing...

The shifter in the W58 had been cut down by someone who had hoped to make a short shifter. Neet to fix that! Here is the original shifter. It has a bushing inside, but no threads. The W58 shifter is too fat to fit into the opening at the bottom of the Corona shifter, so my brother welded on...

My wife is a fashion designer, and is a pro at making anything out of cloth. She brought me a big bag of very high quality black leather from her work, like what would be used for a high end hand-bag. Here she is helping me make a new shift boot An old tshirt More of the shift boot...

The interior of my car needs a lot of help. The carpets in front were so worn out and impregnated with so much nasty old dirt, I just threw them out. I found replacement carpets here: http://www.stockinteriors.com/CutSewnCarpet.asp?Itemid=6628&MakeId=28&ModelId=499 I haven't ordered yet. Not...

Hard to see in the photos above, but to mount the pumps I insulated the mounts with chunks of rubber to cut down on vibrations transmitted into the chassis. I also made a small bracket for mounting the EFI pump, and insulated that with rubber as well as wrapped the pump with rubber. Noisy...

(A few pages/years back you can see a similar fuel setup but with different components. When I switched power to those pumps they sounded like a frelling hovercraft! Maybe that Summit stuff if good for a ProStreet drag car, I wanted a more streetable setup. Besides, I had removed and sold the...

The car is back to the bay area! I set about cleaning it up some. Got the wasp nests and ants out of it. The spiders under the car are pretty persistent though. Since bringing the car back, I have slowly started working out systems and components needed to get the project going again. I...

Wow time flys. All this seems both really long ago and not that long ago. This project was really pretty ambitious, looking back. I got frustrated with the Corona because I really had no idea what I was doing. I needed a car, I had to focus on school, I wasn't working much, life changes, all...

Yeah well as soon as its running I will let you give me the first offer on it. I think the reason the new motor isn't starting is because it might not have compression. :( Checked just about everything else. The timing was way off, but its all sorted now. Either the coil is bad and that tiny...

Hello ladies and gentlemen! Thought this thread had gone to Davey Jones' locker? Well it did truly die for a while. Lots has been happening in my life over the last year and a half, and the Corona project had to be shelved. I packed up everything and towed it out of town to be stored at my...
