If that conniston green is single stage paint (no clear) it will polish up really nice. Just get a DA and foam pad and have at her with some one step polish (or multi step if you are so inclined).

For a 4.6 in a 14CUX people would generally use a 4.2 chip out of an LWB. I probably have, well, I know I have, a spare, it’s somewhere. Honestly it makes no real difference. The 3.9 chip works fine and maybe someone already changed it given it has a 4.6. I am trying to remember, but I think NAS 110 have a 14CU ECU where the chip is soldered, but I would need to check the stack of ECUs I have. You can swap cases between a 93-94 defender ECU (which has the right mounting brackets for a NAS 110) and a RRC/DI 94-95/D90 95 14CUX ECU.

Are you getting power out of the initeria switch? Because if it is bad that would be two truck in a row with the same problem I never saw in 20 years messing with them.

Yep, getting power out of the inertia switch. Pretty sure it's either a broken white and purple power lead to the pump or a bad ground in the back.

More testing today

It's got a clear - and it's peeling something fierce.

I think there is a ground back there for the pump. Maybe on the crossmember. I need to check. When you give it direct power, are you giving it a ground too? How do the attachments/plug with wires for the fuel pump look? I can go get pics of the harness and pump and take a look on mine as it is all apart. It seems odd that the wire would break so I am thinking it is a ground issue or a connector issue. If you give it power only and it stops running, it is the ground. If you give it ground, then its power.

If you are doing the rear crossmember pulling it apart will likely reveal the issue. Rear crossmember is not a terrible job on a NAS 110, just figure out what you are doing with the saddles on top of the dip in the rear frame as those rot the frame under them and are not accounted for in a crossmember with extensions. I cut a set off is memory serves me.

That's a good quick and dirty test I hadn't considered. We're also leaning towards a ground, but will test continuity in the next day or two as well as looking at the grounds. Between work and DST - there aren't a ton of lit hours.

Agreed - just want to get it running/mobile soon for moving around as we approach taking it for major surgery.

I’ve still got #145’s harness sitting in the garage. We checked the harness and found grounds that go behind the left and right rear speaker covers. When I took 145 apart, those fasteners were so corroded that i just had to cut the ground wires. Hopefully this solves the problem, but first the rear jump seats have to be removed...

Didn't get much/any work done today, but I was able to get the service records from West Coast Rovers. I now know exactly what ECU & cam were installed and when - which puts me way ahead of playing the guessing game. A big thanks to them for that - it really helps a TON.

Pulled a rear seat yesterday - with rusted bolts everywhere it took much longer than we'd have liked. But we finally got access to the drivers side grounds. We cleaned up the corrosion and move the ground to another spot on the chassis. No luck starting. Hopefully I'll have some good (warm) time today to get over to Jims and do a proper oil change and keep tinkering.

In other news - I read with interest the article in this weeks Rovers magazine about Woody Woods. According to my records from West Coast Rovers, Woody was an owner of #66 & if you take a look at the picture of Woody with his 95 NAS in the magazine, you can get an inkling of what this 110 looked like when he owned it. It is my understanding that @lordhelemt bought it from his son Chris Woods. I'm not quite certain whether the Woods family was the original owners or not - as it seems to have been in NYC for the first ten or so years of its life before it ended up on the west coast. I've asked @Z.G to see if RN can reach out to the Woods family for any picture of the 110 when it was owned by them.

Small world these rovers

Love it! looks like a gem of an NAS 110! You have some great cars, that 2006-ish cummins 2500 is pretty much appreciating in value as well!

HA! Most of those belong to Jim - I've only got the single NAS 110 and an ROW 90 that'll be for sale here shortly. Gotta fund this resto somehow

Continued slow progress. Managed to change the oil and added a quart of high mileage lucas oil additive. I'm also isolating the no start issue to a series of intermittently faulty connectors in the harness. Pulled a portion of the harness yesterday off of the rear x-member and temporarily deleted the 6 plug sub harness connector.

Also ordered up a fresh set of relays and fancy led light up fuses.

After eliminating many of the connectors between the main harness and the fuel pump, we still had some oddities. We were seeing power everywhere we tested, but never getting the pump on. We also found continuity between the positive and ground of the fuel pump connector. Assuming this means a short somewhere up the line in the harness, we made the decision to jumper out of the inertia switch directly into the fuel pump, bypassing the body harness all together.

SUCCESS!

We got it started up and let it slowly come up to temp. The oil pressure gauge is non-responsive, assuming that the sender or gauge has bit the dust. The oil pressure light went off and as it warmed up, the 4.6 got quieter and quieter, eventually sounding like a sewing machine. We drove it up to the local gas station to throw 5 gallons of fuel in the tank an get some victory Taco Bamba (and Dos Equis)

I need to chase down some wiring in the brake lights - but that shouldn't take forever. Once I get them sorted I can get a VA inspection on it and start tackling a myriad of other concerns.

As was mentioned earlier - one of the owners of #66 was Woody Woods. Thanks to @Z.G I was able to get a picture of the 110 from his family, as Woody had it on Hawaii. Generally I like this look and think I'll shoot to restore it to Woody spec with a few modern conveniences.

Small steps.

The heater core was looped out of the system, but fortunately the heater hoses were left in place. We re-connected them and added about half a gallon of coolant to the system. The heat blows nice and hot. Also of note, the AC clutch turns on w/the little green button on the dash, so we know at least part of the AC is working.

I also got my cable in for the 14cux, and was able to get RoverGauge up and running. Handy to have the ability to interrogate the ECU, I may look to get it up and running on a tablet or raspberry pi for a more portable solution. You can see here that we're running R3038 - a generic Defender 3.9 tune. I need to sort through all the ECU's we've got around here again and see which ones are socketed, then I can get a tune that is more suited to the 4.6L - there's likely a fair bit of performance left on the table.

All in all - another good day, getting more and more comfortable with this engine at every turn.

Before I start searching - what's the best method to burp these things without getting coolant everywhere :)

Spent the early hours of the day driving between DC and nearly Pittsburgh to drop off the replacement bulkhead and a rear x-member to be dip cleaned. This will take everything off of them, and then another procedure for any rust. After the bulkhead is repaired, they will be galvanized and powder coated.

I need to clean up all the grounds mentioned above and put them into a bus bar (thanks to @lordhelemt for the tip) and that should clear up my brake light issues. I may be able to squeeze in a VA safety inspection on Friday. VA DMV is currently scheduling appointments out to Feb - but I've heard some more immediate spots open up around midnight. I'll give that a try tonight and see what happens. I can't imagine waiting until Feb for a title / plates.

Squeeze the upper coolant hose repeatedly once the thermostat opens up with the cap off and I have not had an issue getting them burped. Can’t remember if the 110 has the tower with the plastic cap on it on the passenger side above the valve cover, but that is the high point if you need it.

In addition to driving over 400 miles today, I had some time to get all of the rear drivers side grounds routed to a single bus bar - totally fixed the faulty brake light issue. These ring terminals are way too big - but they'll work for now and I've got a feeling we'll be replacing this rear harness sooner or later. The good news is that I was able to confirm moving to a ground bus fixed the issue & I'm one step closer to a VA Safety inspection.

Had the BF Goodrich AT-KO tires Tommy had originally purchased for the truck mounted and balanced - we'll get them put on tomorrow. Also got some new windshield wipers installed.
