Ok I bet the wiring harness is bad because I tried using my ac which is also a wire off the harness and it doesnt kick on...

 

Yup that will do it!!Hopefully you have another harness or can find the bad spots with that one!!I assume it is a used harness you got with the lightning take-off.
This kinda sucks,now we prob don't get to hear it run

 

I thought your AC went out awhile ago when you heard that hissing noise - like air leaking. That was some time ago tho , you may have fixed it - don't know , you posted that and I think others posted as well it was prolly the AC. I remember waiting for a post about what the problem ended up being - but you never posted it .

I heard air pressure exscaping in the past and it ended up being the AC failing ..

Easy just checking if voltage is getting to the IAC or a continuity test on the proper harness line itself. Might be missing pins on the other side of the harness as well. Truck may not be wired to receive a lightning harness. - idunno?

 

no i have no idea what made that noise, but i put my factory harness back on and had to extend several wires, but no more codes, and everything works like it should, but still wont idle... im uploading the videos now

 

DANG - does the MAF look okay?

 

yep, it came off a running lightning... Here is the first start video!

 

Yea the weird part about it, it was a brand new lightning harness... But my factory harness is working like it should, but it still wont idle, has to be in the tuning...

 

By the sounds of it , your prolly right. It sounds good , so far - Like Normal , for a kicka$$ powerplant.


But , have you had it running long enough to heat up the O2's? I don't think it will matter the way it just goes down to nothing , it might a little if it's not to far out..I bet your right about the tunning.

Still could be the IAC stuck shut..Usually it will idle super low when that happens- hard saying in this circumstance..??

 

yeah i drove it to auto zone to buy some stuff. I gave it almost 1/2 throttle and it boosted to 15 instantly and talk about some G's! then it blew the fuel pump fuse and died... I figured the engine seized lol but i saw that fuse then later realized i didn't have the tps wire connected to the fuel pump controller, which blew the fuse. it runs so smooth on the highway, sounds really good too, it sure does crackle a lot when i let off the gas, that makes me think something is up with the tuning too. And for the stall converter, it feels like a new tranny, it holds so tight. the wine from the blower is amazing :| I put it in neutral and revved it by a gas station, made everyone look lol. I haven't had it past 3500rpm though, i cant imagine how it will run and sound when im slamming the gas!

 

AWESOME!! - Congrats so far Joey

 

Oh and one more thing, I must have got the float on the fuel pump against the tank, it wont move past 1/8 tank o jeez more work ahead. Oh and for some reason the coolant sensor isnt working... and I think the knock sensor needs replaced, long story, So tomorrow ill probably pull the whole thing back off and replace the knock sensor and see whats up with the coolant sensor... anyone have any idea what a sign of a bad knock sensor is??? also, my headlights come on with my parking lights now...

 

Ok here is a better video!

 

I think ill check that tomorrow, but I have the tuner idle set at 980 in neutral, and i can get it to idle at 500, and 860 in drive, which actually idles at about 550-600, but it will die when i come to a stop if i dont touch the gas. I know its nothing serious, the engine runs smooth as can be, and has great oil pressure, im still happy

 

That Blower sounds wicked!! She must really fly...

 

40 miles so far! just thought id let you all know
