If everything checks out and it does not start I would replace the ECT and the IAT sensors as they may not show up on the self-test and they can keep a cold engine from starting if they say hot when it is cold.

Would you mean the IAT sensor Subford? Located on the lower intake manifold right near the fuel rail on the drivers side? Would this be the booger http://nmra.adaware.net/wp-content/u...lley-07600.jpg?
I kind of thought of the ECT but did not know about the other sensor. This situation has only been going on with the onset of these subzero temps we have been having here.
I also went and borrowed a ICM (black one) from a friend who knows it's good and tried that today. Still not diddly squat!
I guess I'll try those two sensors. It can't hurt! At least I will know that there are two more things ruled out of the equation. LOL!
It's dark out and I kinda looked with a flashlight and didn't see it but I'll look again tomorrow.

So it could be one or the other sensor.

Ooops!
I found an article on Full Size Bronco that said after 1994 the ACT/IAT provision in the lower intake manifold was deleted on the 5.0L/5.8L engine and relocated to the air filter box. They also said that they believed that is when the name changed from Air Charge Temperature (ACT) sensor to Intake Air Temperature (IAT) sensor in order to indicate it's new location.
I don't remember there being any wires going to any sensors in my airbox but I will look and being that this is an '89 engine I will still look on my intake too although I used the '96 engine wiring harness.

Your diagram above shows a MAF at the air box and mine does not have one. It has never had one. Is it possible that the ACT/IAT is there without the MAF? I know the intake "runner" tubes do not have any wiring or sensors on them because they are out of the truck now so that I could reach other things during tests.
I'll be right back! Going out to the truck to take a look now.

Okay just ran out and got out the megawatt light and looked and I have an ACT/IAT on my intake manifold located here http://www.supermotors.net/getfile/7...-locations.jpg and it plugs into my '96 harness. Kind of strange considering your diagram shows it should be in the airbox and the thread on FSB saying that in mid-94 the ACT/IAT provision in the lower intake manifold was deleted on the 5.0L/5.8L engine and relocated to the air filter box being that it's an '89 engine and a '96 wiring harness.
Strange things going on in the Ford world isn't there!?
I guess we are exploring the unknown and irregular together then! I am going to look further into this and see what comes of it!
DAMN Ford! I love them but they are testing my patience!

I'm telling you this truck is as stock looking as you can get! It is pristine in every aspect of the word! The only thing not stock under the hood of this truck when I got it was that it has a K&N filter. Otherwise FACTORY! If someone fooled me on any rewiring they would have had to take the entire wiring loom apart/rewire and replace it.
I have seen some botched up crap and I have seen some competent rewires but this is factory all the way. Besides the '89 swap in engine that I did. This engine compartment has not been altered.

I did a KOEO test but in the manual it says that I should warm the engine up to op temp shut it off and do the test. I can't do that so I did it without the warm up first.
My truck is an OBD 1 truck. No 16 Pin connector under the dash. Flash codes on the KOEO codes using the CEL where 11, 33, 63, 14, 16. I could not get Continuous Codes because I had already unhooked the battery.

You say you used the 96 PCM Computer with the Black ICM and with that all of the codes would be three digit codes not two digit codes.
Besides that if you did had two digit codes and you got a 11 you should have no more KOEO codes after that.

Here's what I would do next:
See if it'll start on starting fluid. Maybe put a fresh set of plugs in first, you've probably fouled the existing pretty bad by this point.
If it catches, then it's a fuel problem.
If it still doesn't catch, then move on. I'd probably do a compression check next. You say it's an '89 engine, how many miles on it? Maybe the timing set skipped a tooth, or maybe even broke a few off.
BTW, instead of throwing tons of sensors at the truck, just unplug them. The ECU will go back to preprogrammed info and disregard them since they're unplugged. No it won't run right, and it'll set a CEL, but if its that particular sensor keeping it from running, unplugging it will bypass it.
