Try both methods in this order (even though hers is a OBDII)
Older (OBDI) models - Start with the ignition off. Within five seconds, switch the key (without starting the engine) on, off, on, off, on. ("On" is NOT "Start" and "Off" is NOT "Lock"). The "check engine" light will flash. Count the flashes. Each code is a two digit code, so a (for example) 23 would be FLASH FLASH (pause) FLASH FLASH FLASH (long pause). It will never flash more than 9 times, so watch for those pauses!
Newer (OBDII) models - Put the key into the ignition, push down the odometer reset button, then turn the key to RUN with your finger on the button - and then release the button. The odometer will go through 1111111 through 999999, then display the car's serial number. It will then show the error codes (it might show them starting with P). If this method does not work, try the OBDI method.

Well it wasn't the tow guy right on the spot. They towed it to their shop, checked it out, she thought it was her alternator because that went out on her GMC and it was similar (electrical probs) then they checked it at their shop and said it was the computer, and towed it to the dealer to get it done...
...the same dealer thats ripped my mother off numerous times, and now her car has a blown motor because of their ignorance.
And of course...
Shes jailbait til the 21st...so dont get any ideas

quardatokn, I know I browsed past a thread here explaining how to swap out the PCM and the BCM or maybe it was two threads, but now I'm having search troubles...
If it does happen to be the PCM that needs to be replaced, or if you're still interested in this, do a search for "PCM" and see if you can find it - I know it's here somewhere, and it left me feeling like I learned something, so...
