We just got done installing the new motor, and the car wont even crank over

odd notes:

the radio stays on even when the doors closed and keys out and locked?
no security light, no cel,


the car just wont crank over, everything else works, the starter is getting power too

 

From my recollection you can't just swap a motor in. You have to do a whole learn of the new motor to the ecm for it to crank due to the increased security theft deterrents in newer vehicles

 

yea ive herd the same thing ^. it sucks but maybe you can call gm or something and they can help you

 

this is not true. i swapped engines without any relearn. i simply installed my base turbo tune and it turned over. i suggest you check your grounds we had no issues with my build and install but i had a certified pro installing it in his garage. the **** ass never missed a beat. is the valvecover gronded to the head? recheck all youre grounds and connections.

 

Ur missing a ground on the motor mine did the same thing after we took the trans out and we forgot to hook up a couple ground straps

 

He speaks the truth. I missed the ground from my starter to the bellhousing and it wouldn't crank. You've missed a ground somewhere.

 

nah i had the ground on the power on the starter lol, shoulda updated this a while ago, cars running great
