Finally, some progress!!

Or better still is to replace the brittle connectors.

I'm finally doing what Kelvin told me to do 2 years ago...

I built a brand-new harness for the front of the motor, new connectors, new wire, new wrap. And added new cam sensors. A few new connectors for elsewhere on the motor. I'm not used to such nasty brittle connectors, and it's so nice to have new ones in there. Should have done it in the first place.


It felt so good to actually put stuff together. Put that all on, with my new timing components. And put some oil in it. Kids were sleeping, so I couldn't fire it up, but hopefully this weekend I can make some noise and progress.

It's not my priority, have 2 cars to fix and sell, and want to get my van road-trip-worthy by August, but now that winter is finally breaking and our son is sleeping better (and therefore, so are we), progress is a little easier.

I spent some time this weekend chasing some odd issues.

First, it took much longer than I expected to prime the oil system, but finally got it to reliably trip the pressure switch (which, is only a few psi, but it's something).

Then I got everything plugged in, battery hooked up, and went to fire it. ECU is running the fuel pump (via the stock pump controller) and screw on the damper is rising, my aftermarket tach is registering cranking rpm, but no life on starting fluid, and inductive timing light does not flash on either coil wire.

After some more experimenting, there appears to be some residual voltage on MREL after shutoff holding the ignition relay on. It will stay on until the battery or relay is disconnected.

Jumpered TE1 to E1 to check for codes, and the light flashed continually at first. Then every cycle after that, it would just stay on steady.


So, I need to spend some quality time with the multi-meter and see what exactly is going on. I do have several temporary connections, as I'm intending to build a new fuse box to serve the engine and body together, so I might improve those.

Again, managed a few hours of the last few days. I disconnected my front harness that I had made, and used my DMM to make sure I routed all the wires correctly. I put it back together, and watched the voltage on that Ignition relay. And it worked perfectly, and the engine started right up.

So I moved on. I picked up an alternator for a 3UZ for a couple more amps.

Here's the stud to utilize the 3rd mount on that alternator:

Got that installed. Put the power steering pump on, realized that the reservoir blocked the upper timing cover, removed pump, installed cover, reinstalled pump. I spent some time last night modifying the RH exhaust manifold to get it routed just the way I want.

I've played with the exhaust some more, that's coming together. Slipped some fire sleeve over the power steering pressure line and transmission dipstick tube.

Had a couple hours at home, by myself this morning. Started it up, revved it a few times. Drove it up onto ramps so I can better work on exhaust. It sounds good free-revving with open manifolds, anyway.

Next big project.....fuse box.
