LS won't crank
Hi All, I am to the point on my 57 pickup project that I am getting ready to start it. This is a LQ4 DBW with 4L80E trans. I can communicate with the pcm with my tech 2 no coded stored but won't crank. Trans data shows it is in park and have power at the purple wire going out of the switch. There is a start relay and if I cross the big red to purple it cranks. The green wire on the start relay has power and if I touch the yellow wire on the starter relay it then cranks. I also am getting the 2 second fuel pump prime signal. I am really not ready to start it yet but trying to get everything in order when it comes time. Thank You Steve

Re: LS won't crank
So no power to the start relay when the key is at Start position? You would have to work back from there. Do you have a neutral safety switch in that circuit?

Re: LS won't crank
These threads may help you if it is the neutral saftey switch on the 4L80 trans. They are from when I was researching how to wire up my NSS.
