Yes its the famous no start issue again

I am throwing crankshaft codes and passlock

I am doing case relearn in the morning, however i swapped in an ecu calibrated for 60'bers just to see if it would crank and it seems that it is

What I am asking is basically I need all the diagrams for grounding and the starter and starter relays that I can get my hands on.

Now if I am correct once passlock is fixed the car should fire right up? We did it once today and 4th turn it did not start, any input is welcome im stressed enough without my baby not starting :(

For those of you who do not know, this is a complete factory motor I picked up at the local junkyard 7,000 miles on it brand new starter ac compressor/alternator from old car both working

brand new supercharger with 0 miles on it, rcu to match the motor I bought

*sigh

Took me like 10-14 hours to swap motors with hand tools, 5 minutes to bleed the clutch im getting pretty dam good at everything minus electrical.

dam thing is brand new, the crank sensor error i belive is from my old motor the code is just stuck in there as this motor should be fine

im more worried about the passlock and why when the starter is hard wired that the motor does not turn over

Is you security light blinking? If it is you need to due a theft relearn by trying to start the car and leaving the key in the ignition for 10 mins. I dont think that requires a tech 2. but i could be wrong.

i had this same problem... if your security light is blinking try to start the car if it doesnt start shut the key off and let it sit for 5 minutes then try again if it doesnt start then take it to the dealer... i had this problem 5 times and took it to the dealer and they reflashed the computer and never had the problem again...
