actually the folder the guy at the testing center ( garage) gave me is from the MTO
ministry of transportation Ontario - a government supplied folder that explained the fail and exactly what I needed to do to get enough data into my truck to pass

to be more clear what it said
let truck sit 8 hours or more without starting
start , let idle - something like 3 min with the a/c on
drive 10 min highway speed
drive 10 min city speed
now ready to retest if not less than of 24 hours have passed since the previous try
- passed no problem
- had about 108 KM's on it since the first test - slightly more than 60 miles and slightly more than 48 hours
the only reason it was two days after the first test is because the testing center was booked solid for the day after my first test - so I had to wait for the next open appointment time

I don't care what ford has to say - not to argue with you - all that matters is what the government's test computer wants 'cause that's where I get the pass that allows me to renew the sticker on my licence plate for another year & that ^ up there ^ IS what it wants you go go out and do if it reads a not ready condition on the first try

my mistake was checking for fault codes the night before the first test , THEN pressing the clear codes button on my edge tuner ... oops - but now I know better

not knowing how long it needed to be run after being reflashed back to stock , I'd been driveing it on the stock tune for the better part of 2-3 months previously

to add , there is a trick that works , at least with the older dodge cars - pre OBDII - if you have a modded car with stuff that dosen't exactly belong in it , you can rewrite the computer's indentifying info so that it tells the test computer it's whatever year , make and model you want it to tell the computer it is
- though with mine which had a newer ecu and wireing harness, intake and turbo than the car it was in there was no need to do that , even though the newer system used no egr system while the older set up did
- and that actually passed a tailpipe sniffer test too

- but I have no idea if that could be done on the newer stuff

About the only system that is commonly left go is the EVAP not complete because of it's huge set of test conditions and huge length of time it takes.
To expand on this, some may jurisdictions allow one or more "not ready" monitors. Check your local regulations to see what is allowed. It varies sometimes even by model year of the vehicle.

The cat ones could have been that your truck wasn't warmed up enough before the test?

Since you say there is no CEL, that would be my guesses.

Drive it around making sure you do some stop and go, some hwy etc. It also needs to go thru a full temp and full cool down cycle or two.

Good luck!

Thanks for your reply Mitch, I got it inspected first thing Saturday morning, got up started it up and drove to the inspection place, maybe 10 miles, no traffic. I hope that's the problem.

If the entry criteria are not satisfied, then the test will not run and the monitor flag will remain in the "Not Ready" condition.

You will not pass until you have the requisite number of monitors set to "pass" with no pending fault codes.

Several of the monitors should run within the first several miles of normal driving (O2 sensor and heaters, EGR). Catalyst tests usually take a bit longer. EVAP tests might take days or weeks before running. How much driving was done since the battery was re-connected?

Cat efficiency codes usually crop up after some other problem has been left untreated for too long (misfires, "lean" codes, etc) then finally repaired. What is the recent service history of the truck?
Thanks for your reply...I disconnected the battery on the Sunday before last to clean the battery post. The only driving i do during the week is work and back, about 200 miles for the week. I bought the truck in September of 2013, and it was current on inspection, since then I had the spark plugs changed out about 3 weeks ago, new air filter and fuel filter and of course regular oil changes.

Texas will allow 2 not ready on a 99. I think 2000 is the cutoff year where it changes to 1 not ready. But I dont remember which way 2000 model is treated.

On pre OBD2 vehicles Texas still utilizes a 4 gas exhaust analyzer/tester.

which should be phased out pretty soon. Texas requires vehicles 2-24 years old be emmission tested. So in 2020 the sniffer will be obsolete. However present day, the state inspection computers still use dial up internet to connect to the Texas servers

When did OBDII start up, mid 90s? Oh, I guess 1996 if I do some math

Dial up? Seriously?!

1996 most manufacturers used OBD2 but it wasn't mandated until 1997.

GM actually used OBD1.5 in 1995 which was the new OBD2 connector but it lacked all the monitor and fault code tests that are mandated under OBD2

OBDII was mandated for MY96 vehicles under 8500 GVCW.

Update

I drove it well over 150 miles and retested this past Sunday with the same results. The tech told me that the fault codes P0430 and P0420 should be corrected first. He asked if I had the spark plugs changed recently and i did. He told me that I should bring it back to the shop to have them check the plugs. It is usual to have those fault codes at the same time.

The 420 and 430 codes are the cat efficiency monitor codes for both banks.
Changing or doing plugs won't clear them or have any effect now.
What you have is either failed cats from one of the following, poor fuel used over the long term, ran truck too long with multiple misfires that caused raw fuel to be burned in the cats, melting them, or possible sensor inactivity.
If a Scanner is used to look at the activity of both rear sensors that will tell the story.
If cats need to be replaced, all 4 Ox sensors should be replaced with them.
Replacement assemblies and sensors plus labor will about ruin a 1000 dollar bill.
Good luck.
