Since the weather here has been unseasonably nice , I rolled the engine outside yesterday to drain the oil and put a new oil filter on. Also did a few other things like remove the power steering pump and some general clean up.

I am going to build an engine test stand , so that I can mess with it, instead of leaning over an engine compartment. Should be a lot easier to get it running. I do have to order some flywheel bolts, since the engine was originally from an auto and the bolts are different for a manual.

I also remember a video of a guy starting one up on the floor. Looked like it ran smooth and didn't jump around.

Yea right, still lots to do to that project too! Now you're making me feel bad about not working on that project. :o One thing about the FJ, it's going to be worth something when it done, where the 510's are kind of stuck in value appreciation. But, the 510's are a lot more fun!

Finished the ECU wiring harness down to the test prototype stage. Hooked up the Nissan Consult lll to the OB2 plug, so that I can program the NATS ( Nissan Anti Theft System). The NATS must be programed to allow the engine to fire. One problem though, the Consult won't communicate with the ECU, rechecked the OB2 plug to the ECU. Checked ok, did notice that the ECM relay not closing. Dam, looks like my long awaited Ebay ECU find is bad. Time to put my 39 years of chasing electrons to use. I found that besides the ECM relay not engaging that the processor in the ECU wasn't running, which is why no communication with the Consult. Traced the circuit in the ECU back to a defective mosfet power switch. Found the same part in the G35 auto ECU, removed it and placed it in the Maxima ECU. Here are some pictures of the part placement in the ECU's. Note the size compared to the pencil tip.

Here's the part installed in the Maxima ECU;

After replacing the part, the ECU came to life, the relay works, the fuel pump runs for couple of seconds like it is supposed to. Next, with my fingers crossed, I hooked back up the Consult to the harness. Success, communication! Finished the programming of the NATS, no more security light. Though the Consult, I can control the fuel pump and watch the changing of the voltages on the throttle pedal when moved. Looks like it going to work. Next up is the finishing of the engine stand and hopefully the starting of the engine. Fingers are still crossed, that there is not any further problems with the Ebay ECU.

Update: Got the engine stand completed, used steel from an old tread mill and some cheap HF casters. Wanted to be able to roll the assembly in and out of the workshop easily.

Image

Image

JWT flywheel installed, old VG fuel pressure regulator mounted on the intake manifold for test purposes. Found an old metal gas can that I used to use when I mowed lawns in high school, couldn't find a metal can at the stores, all plastic these days. Mounted a fuel pump assembly into it with a fuel filter.

Image

Removed the power steering pump and the air conditioning compressor. Ordered a shorter belt for the remaining alternator.

Image

Wired some LED's for the oil pressure, Mil light, and charge light. Note: key inserted into Nats antenna.

Image

Hooked up the modified harness to the engine with the repaired ECU, programed Nats , electronic throttle,and relays / fuses. Time to cross my fingers and do a little prayer to the engine gods. Please start, oh pretty please.


IT RUNS!!!!!!

Made a little video;

This is a major accomplishment for the project. Next up is to make a fuel pressure regulator holder that uses a Bosch FPR at 3.5 bar.
