I'm trying to locate the PCM in my '94 LeSabre so I can clean the connections. We're having some problems with it, and I figure it's best to start with the free stuff first.

Look in your passenger side underneath by the glove box pull the lower hush panel down and it is stuffed in front of the glovebox.

What kind of problems are you having?

The biggest issue now is that the fuel pump seems to not work on occasion. We've had the PCM analized, and several small errors came up. The mechanic that looked at it said it may just need the connections cleaned.

We're probably going to take it down to Buick and have them poke around to see if they can pinpoint anything.

I have yet to see a dirty connector on an inside mounted PCM! The PCM does not work the fuel pump after the first 2 seconds on engine startup. PCM only starts the pump to build pressure for ease of starting nothing more.
