Hello,

Doing an ls1 swap into a 65 impala. engine was running fine. I removed the computer to do some welding (seat brackets) and now have put the computer back in and car will not start.

I have 58 psi at the rail.

I get three error codes now. Had none before. first one is n/a, second is p107 and third p118. I had checked for error codes a couple days ago and had none.

I am confused. Any help appreciated.

 

disconnected the intake air sensor and the engine started right up. off to autozone to replace it then to try the next code.

 

Are you sure you got a good ground for PCM?

 

My bad I didnt read second post lol

 

weird thing...replaced sensor, now it runs but I cant get rid of the code. guess Ill unplug the battery over night and see if it goes away.
