Hey guys I half bigstuff 3 in the truck and just so you know what I did leading up to this issue so maybe someone can shed some light on my issue.
First was having a high idle condition after the truck was warm.
So I was checking the common causes. Vac lines ect.
I did find one bad hose from the turbo to the booste valve and fixed that.
I wanted to see what the bigstuff program looked like and maybe some of the info would point me in the right direction.I plugged the laptop in to the serial port and turned the ignion to run. I did not try to start the truck. I looked at the idle info rpm levels and such.
I looked at temp setting and basically looked at stuff. I did not touch any cells or change anything conciousley. I am no computer genious or tuner but I do no my way around without screwing with things. I unplugged the laptop and started looking back under the hood and for the hell of it unplugged the IAC and looked at the pins of the connector and all looked good. Knowing I couldn't do anything with th ECM but was curious what stuff looks like while the truck was running. I decided to hook the laptop back up and watch the idle and stuff. When I keyed the truck to start it I got nothing. It just turns over and sputters but never starts.
To me it seems like timing but nothing was changed other than unplugging the IAC.
Is there anything I can do or look at so I can run this thing to someone more qualified?
I don't want to tow if I can help it.
Thanks
Jeff
