yes the ecu has sensors on the engine that tell it what the engine is doing and theese can be coded to the ecu so a reset is advisable

Sensors are plug and play, no programing needed. Just like replacing a sensor with one from the parts store. Olds does the engine have spark, what's the fuel pressure, and do the injector plugs have a pulse. What year Pontiac did that engine come out of?

Picked one up from the junkyard put all and I mean all new gaskets and sensors on it and swapped them out one saturday

John Saffrahn

Only thing we didn't replace was the crank, cam, pistons, casting plugs, and heads. Everything else was brand new.

Took it out Saturday morning, ate lunch, put the rebuilt in Saturday afternoon and he took it home Saturday night nothing had to be programmed or reset.

Worked at a shop after college in 2009, horrible storm in northwest Indiana. Hydro locked engines at least 2 a week didn't matter whether it was a used junkyard engine or a rebuilt with a warranty, it was all put it in and go.

My point being, you missed something.
