This is starting to become clearer. Went through the wiring diagram and found that the MAF and Evap purge solenoid both share the same "pink wire" 12 V source. And my car is throwing both MAF and Evap codes. It's got to be the 12 V source.

Wiring diagram says that the source is the "Underhood Electrical Center 1". But is does not show that the source from the PCM is fused, just that is passes through this box.

Anyone know if it's fused?

Anyone know where the Underhood Electrical Center 1 is?

Thanks...Boatman.
