Ok I'll try this again. Went I say open I meant that the valve was extended all the way out. But I'll give it a go again. I also tried starting it with the valve removed and plugged in. Still no go. What it's doing is starting and running for maybe 1-2 seconds then stalling.No, fully seat the IACV closed. Turn it until you cannot place the assembly fully seated, then back it off a hair until you can fully seat the assembly in the closed position. I had to do this on mine when I was running the IACV power off a toggle, then the toggle switch broke in the off position while running, wired it up correctly and then tried all methods with the IACV, fully closed is what worked for me, makes sense since the engine is cold when trying to start it, so it is "choking" the extra air.
