I have my swap almost done but i am running into a few issues
1. I can start the truck but it runs only for a few seconds. I did send my PCM in so it should have VATS removed
2. If the Key is in the on postion and i hit the throttle pedal the throttle body does not move at all, is this normal for a DBW?
thanks
Who did the PCM, it sounds like the VATS are still activated.

well i plunged in a scanner and am getting Codes P0220 and P2135, could this cause the engine not ti run for more than a few seconds?
Absolutely. Have you cleared the codes and tried again? Will it signal fuel pump voltage?

i am getting correct fuel pressure, i have cleared the codes but they come right back
Brother was getting code 220.
His throttle body wouldnt open or close with the pedal either.
Turns out it was the sensor on the pedal, maybe check yours, as he replaced it and the throttle body operates with the pedal now.
Still wont start though...and still getting the same codes...haha...
LSX conversions, so easy a caveman can do it.
well the not running for more than a few seconds is fixed, it seems the MAF was not pluged in all the way, But i am still not able to get the throttle to open
Unless there is something with the tune I know nothing about (very possible), the throttle will not open and close by actuating the pedal....whether or not the engine starts and continues to run.
A start and stall is usually a theft system problem. Off the top of my head, those DTC's will not cause a stall.....just usually reduced power mode.
