Most likely...the "CPS" module is going bad. This is a power supply module under the dash, that supplies a 7 volt supply to the dash panel AND the BCM and climate control system, among other things. When it fails,. the dash will go blank EXCEPT for that "electrical problem" message--and the climate controls will NOT work, and such....and if you have the VIC, as I do in mine--it will kind of be "frozen" while the problem is present. Re-starting the car will usually "clear it up" for awhile. My own 1989 trofeo has this problem a BIT, every few months or so...it will "do it" and I have to reset it. If it starts to get worse--i will get another CPS or try and fix mine. Mine--and maybe yours--have bad connections most likely....and should be easily fixable, and maybe a couple of bad capacitors too.

As someone said...these old cars are a LOT of fun to drive, and frugal on gas and such...but at this age...they need some 'care and feeding" from us to keep them running, and performing, good.

Drive cycle reset


Drive Cycle resets to reset the OBDII testing phases are very specialized to the year, model and engine of your car. So I can only speak generally. Start the car from fully cold and let it idle for about 15 minutes, then put the car into gear and drive it for about 5 minutes at 35 mph, then get on a highway and drive at about 60 mph for 15 minutes, come off the highway and drive around 40 mph for 3 minutes, come to a complete stop (like a stop sign) wait 30 seconds, drive off again up to 40 mph for 4 minutes - and repeat the last 2 steps (going up to 40 mph) about 3-5 times. Then repeat the last two steps going up to only 25 mph. Then come to a complete stop in your driveway and let the car idle for 10 minutes with the a/c on . After this is done, hook up a code scanner and see if it reset the modes to "ready".

there's a main relay or fuel pump relay located under the dash on driver's side. this relay goes bad all the times. it usually goes bad when you leave the car in a hot sun, next time keep your window down to see if it will start.

Electrical problem


Sounds more like electronic ignition switch. Coil or voltage regulator would display loss of power during acceleration, power surges (fuses blown).

Sporatic problem with Stereo and Stereo Display


I have had this problem intermittently since I purchased the vehicle in 2004... the dealer could not fix but showed me that there is a relay that you can pull and re-install. It's under the hood and must be done with the ignition and lights off. Pull the relay, wait 10 secs and re-install and pblm goes away. If you are standing in front of the vehicle there is a relay box on your right/vehicle left. The relay is located in the lower left-had corner of this box. Not a permanent fix, and in my experience the problem goes away when the vehicle is parked for an hour or so but if you have a long drive and want to use the radio, this 60-second fix is worth knowing...
