If it does while cranking, it will shut off the fuel injectors...

I can crank with 0% throttle and get 9.6ish ms then go to 10% and get 3-4ish then 100% and get 0 all on the text data page.
But I think I found the problem
I decided to do the full on test you prescribed Ted.
I pulled the UIM and peering in the secondary runners with a flash light I had my dad turn it over. BOTH secondaries fire while cranking on staging mode? odd (and yes they are powered by the pink and green wires....pink being on the rear rotor)
Then I undid the primary fuel rail, un plugged the secondaries, held the primary rail out of its spot, cranked it over and got the front rotor only to squirt gas!!!!!
YAY RIGHT?? foudn the problem? burnt out injector yes??
Well I switched the plugs from front to rear on the primary and now the rear gave me a spray in the arm....
Both are getting + voltage. both have continuity through the connector I installed.
Burnt out injector driver in the ECU?
Everything else seems to work on it (as far as what I've hooked up, I haven't used the road speed feature and such) just not both primaries.
And also - should the secondaries be firing in staging mode during cranking? Because they did.
No idea why I wasn't getting any gas in the first palce either, it just decided to spray one day.

also, I'll be checkign the harness tonite for continity of the groud side of the #2 injector wire between the ECU plug and the actual injector plug to rule out a split harness.

Haltech set to STAGED.
You get 3 out of the 4 fuel injectors firing under cranking???
Something is seriously wrong - only the primaries (or only 2 of the fuel injectors) should be firing.
It sounds like you got a wire crossed somewhere?

Yes Haletch is on STAGED (yes, I've been reffering to it as staging. Oops
)
And YES 3 of 4 fire during cranking on this mode.
And yes I get both sec. and one pri. injector firing. They are wired as previously stated and there is nothign wrong with the connectivity of the injector connectors themselves.
I could make the not firing inejctor fire by switching its plug (the dead wire is the dark blue #2 injector wire) with #1 injector. So the injector itself is also fine.
I am going to check the continuity of the harness tonite as a precaution but with the altogether sketchyfuel problems (like no fuel, then lots without changing anything) I'm leaning towards something inside the unit.
Has anyone ever heard of this before?

Did some more investigating last night....
CHecked harness for continuity for all trigger wires and made sure they were in the correct locations. Tried firing it up with the ECU in the air (ie. the case not grounded) and then again with it back in its location. All to no avail.
Interestingly as well, I get - again - no gas at all in staging mode. Then I can try it again after turnign the ECU off and on again and the secondaries will squirt during cranking in staging mode.
In multipoint only the secondaires fire, or the secondaries and front primary. No rhyme nor reason to their operation.
The Haltech is all tucked away is a giant pile of bubble wrap on its way to Temecula California for repairs.

Just heard back from Haltech, apparently my unit has a bad PLD. I don't know what that is and neither did the phone jockey who called.
Could a bad PLD have been caused by something being wrong wiring wise or base map wise? I don't want anything to happen to the new (yes new, they said it can't be fixed) unit.
Thanks for your help guys.

Yes, that could cause all the headaches.
The PLD takes it's commands from the comm program and is suppose set all the outputs (and inputs) properly.
This is the reason why you were seeing really weird fuel injector firing patterns!
Glad to hear the problem has been found!

Thanks for the link Ted.......
Yes they were covered. I paid for shipping there and back (about $100 total for priority) But they actually sent me a whole new unit, said mine couldn't be fixed.
I was glad and am very pleased with the service. Tonite I'm goign to try firing it back up
They called me yesterday with the news and the Haltech got here about 15 minutes ago. Go Fedex! lol

FWIW I have a strong suspicsion that whatever was wrong was caused during the initial shipping. The harness I got with the unit had a chunk of plastic broken off of it that was present in the box when it arrived. I'm sure when it left the plant or wherever that it DID work, but with what happened to the harness I'd say it got kicked aroud a few tiems before it got here.

Fired right up:
-Idles like a champ at 1300rpm
-Revs beautifully
-Cleaned up my static AFR's last night.
-Get my Volks and tires back next week and then we road tune
Me = Happy
If I can make a 7 with a broken Haltech idle, I should be able to make one witha functioning Haltech run decent

I would post it, but I don't feel like having a certain Texan coming to hunt me down with a chainsaw 
If you have a BP or HBP, talk to BDC he'll fix you up with a map.
Really though any BP map should work well enough to fire the car, provided its setup for the ignition you're using and the injector sizes are the same (or very close)
Its the load tuning that needs to be spot on for your setup. Firing/idling of a HBP can be done on a stock N/A ECU for cryin' out loud
