error codes help

**leon phelps** · 02-13-2012, 06:10 AM

Hello,

Putting an ls1 into a 65 impala. engine was running fine, had no error codes. I took the battery out then the computer out to weld in seat brackets. I replaced the computer. Now car cranks and does not fire. It did fire last night, but not today. I have 58 psi at the rails.

I get three error codes now. First says n/a, second P107 and third p118.

I am confused how a running car with no codes all of the sudden has these errors. Any help appreciated.

It does sound like it is cranking a little slowly, Ill put the battery charger on it.

update....I disconnected the intake air temp sensor. the car started right up. off to autozone to buy a replacement. then on to the next code.

Glad you got her going. Are you doing a thread with pictures of the build? Sounds nice...

I have a million photos of just about every step of the build. Floor pans, Ls engine, wiring, disc brakes....Cant get rid of this p107 code even with the new part. The second code went away when I found I took the plug off mistakenly when fussing under the hood.
