Yes. Unless the vehicle is pre-1976, which its emissions are waived. All others must test either once every year, twice a year for certain year models and once every three for newer vehicles.

Would be awesome if I could swindle that. Must research more on it. As for seeing it, as soon as I get her on the road, which is hopefully soon.Dang, thats a rough one. Lose that title and request a new one, insist its a gas truck this time?Good luck man! I'd like to see this thing in person sometime.

I’ll post some pics of the beast tomorrow when the sun is out.
This is a weird scenario. I have never heard of plugging in a older diesel during inspection. Usually safety only and maybe tailpipe testing. My 96 F350 doesn't show anything when I plug it in with ODB unless I have the fancy Ford programming.
I guess every county or state is different for testing. My title doesn't even show the fuel type on it so I didn't even bother changing anything with the state. I just show up once a year and say "I need diesel inspection", pay my $7 and leave.
Post up some photos as I am like others and want to see this conversion.

It's being plugged in because regardless of the engine, the vehicle requires OBD to be read for the test.
I researched what it'd take just to put an LS variant in my 96 til I bled from my eyes...I'll be staying with the 1fze to avoid the headache.
Where did you buy the truck? I think I drove it years back when I was shopping for mine. It was near Golden.
I'll say this much...it's not going to be easy to pull this off. You need to find out how it was registered from the previous owner and hope that gives you a head start. Buying a swap is always a gamble in Colorado...

@LesChao the laws regarding motor swaps in colorado seem relatively simple. Your motor has to be from the same year or newer vehicle. You wont have OBD2 from a military HMMWV, the simplicity is what makes the swap so appealing. That being said, your emissions tester is trying to plug into the OBD2 because your vehicle is an OBD2 vehicle and that is what their computer is telling them to do. I would explain it to them that the diesel is out of a military HMMWV of proper age and they didn't have OBD ports. Request that the vehicle be tested on the rolling sniffer/Dyno. If they tell you no then ask for a supervisor and explain the situation to them. That the vehicle has been modified and cannot be tested through the conventional test their computer is telling them to do. Ask to be tested on the Dyno....thats the only way I see you getting it done. Its strange how your county tests diesels only and not other vehicles. Why a state would have different testing in different counties is beyond me. Its reminiscent of how the Portland (extreme north) area and Medford (extreme south) areas of Oregon emissions test but the rest of the state doesn't.

Yea you are talking to the wrong emissions guy at the station. You need to go higher up the chain of command.
Even in bureaucracy ridden Spain, diesels and petrol engines are tested by a simple sniffer in the exhaust, this is regardless of age or whether OBD fitted or not.
From new, vehicles are tested at 4 years old, then every two years, once 10 years old once a year.
My diesel van is tested every six months due to being registered for commercial use, this would be the same if it was run on petrol.
Despite multiple provinces I am pretty sure the above are national rules.

I’m going to guess that as a gas engine, they’d still want the OBD test due to the year of the vehicle.
In addition to what @LandCruisinMy93 said, I was under the impression that diesels only had to pass an opacity test in CO, which is done at authorized independent shops, not the awful air care stations.
Not to throw another monkey wrench into this but be careful with dyno tests. From my understanding you need a dual axle dyno with the AWD vehicle so as not to damage the transfer case, more likely it shouldn't be put on a dyno at all.
You can pull the front driveline and lock the center diff and run it on a rear wheel dyno, if that needs to happen.
CO has awd dynos for emissions tests.
From what I remeber of CO, you nees to go to an independent diesel shop certified for emmisions... not the typical state facility. I also believe that CO uses opacity requirements for diesel. Go to the diesel shop and ask.

If anyone is still watching this thread, all is good with the rig. Had to set up a mail forwarding address and register in a different county. So if you know anyone that has a similar issue, let them know there are work arounds that don’t cost thousands! Thanks for all the advice!
There was never any ECU-like device for any of the Toyota diesels factory-fitted to 80's here in oz. The only engine that gets electronic control to suit an 80 would be the 1hdfte (the 'e' bit is the clue). 1hz/1hdt/1hdft are completely mechanical with the only electrical area being the glowplug control for starting.
There's no way (easily) to sensor-up an older pre-electronic era diesel to be able to provide data to an OBD box, let alone actually be fully 'compatiblised' with OBD.

How is it on the title as diesel? I have had my diesel swapped since 2009 and just retitled and changed my plates over from Kansas to Colorado a couple months ago and I put DIESEL on the title application and when it came in the mail its blank under the fuel type. I never had to start it....they didn't care.
I called since I wanted Diesel on my title should I ever need it for insurance purposes and they told me CO doesn't use the fuel type box.
Here in Spain it is all about provinces as well. I can drive through one 10 minutes away and be illegal, mainly due to the seat count. A friend just had his Misubishi fail on the two front spotlights mounted on the bumper, it has been passed in one province every year for the past ten, he could not get an appointment so drove a few miles up the road.......failed.
You can get cheaper car tax if you register in another provunce as well, go figure.
