Wont stay runnin


It sounds like the same problem I have on occasion with my 1994 GMC Safari van. You need to check your AIC valve ( air intake control) it may be bottomed out wich is the reason it starts but will not stay running. Now I also have another possilbe solution ckeck to see if your catlist converter is not plugged . Not shure why but these are some of the solutions that I have for what happenes to my van . Hope this info can be of some help.

Brake lights wont turn on.1994 gmc sierra.


This may sound too simple, but first verify that you are getting voltage to the light socket. Use meter on d.c. If you are getting voltage, and your bulb is good, it could be a bad ground. Don't overlook the brake light system goes through the directional signal in the steering column.
