Is it possible to narrow down the circuit? There are quite a few. i have personally worked on a 92 3800se and rebuilt the wiring harness. the best place i could figure to get wire schematics is to bug the guys at the local Pontiac dealers body shop. it took 20 min of hassling but i managed to get print outs of the schematics. the following are the various harnesses. -body wire harness -dash harness i should note that those are the main harnesses. however they are sub classified as everything from power locks/windows, engine compartment harness, instrument harness, ect....
It is possible for the check engine light to come on in a Pontiac Transport when using ethanol gasoline because it burns hotter than other gasoline. The check engine light might also come on if the oxygen sensor is bad.
