    Thanks for the help. Someone cut out a visible link behind the battery. Not a good connection.

I think you have a short where the wiring harness plugs into the fuse block .I'ts located on the
firewall,just above the battery. Look at the lower left corner for signs of a hot spot,melting or
burned wire.

Sounds like you may have problems with the ignition switch. The starter is turning over? But the motor doesn't fire, until you turn the key off?

SOURCE: need to find out my engine size

There are two ways to identify the engine you have. First way is to locate the white emission ID label located under the hood. This label is white with black print, about 2" x 4" and will say something like "this vehicle conforms to such and such for model year 1987...." and somewhere on it it will also have the engine size in liters such as 4.3, 5.0, 5.7, or 6.2 Most of these vans came with the 5.7L [350 cubic inch] engine. This label usually is on top of the radiator shroud, bottom side of the hood, or one one of the supports [it varies] but should be fairly easy to find unless it's been removed or lost somehow. The second way to determine which engine you have it to find the 8th digit of the 17 digit VIN number. The letter Z means you have a 4.3L, H is a 5.0L, K and M are 5.7L engines, and J is the 6.2L diesel. Hope this helps out!

Died while driving and now will not start. getting fuel and fire 1995 GMC Vandura just stalled while I was driving it. It won't start now. any ideas what it may be?


I would bet first to check and change would be cap and rotor and coil. Lack of proper spark at proper time is the main issue, that or the timing chain jump a tooth due to age and wear.

Low beams stopped working high beams work fine


Either both bulbs are bad(I've seen it before) or your
dimmer/headlight switch is bad. If you can without pulling the bulb, pull plug from the light. If it's a 4 lamp system pull the low beam. Do this on the left side as the right feeds from the left. With a 12v test light, check for power. (with lo beam on) if you have
power, change the lamp, if you don't it's most likly
the dimmer switch at the steering collum.
Hope this helps Good luck

92 gmc seirra headlight go on and off but does not affect parking lights or tailights. I have already replaced the headlight switch and checked the grounds. I even put a volt meter on the battery and dont...


OK, This may not be a 92 gmc solution but I hope it helps. I had this problem on a non-gmc. The Hi-Lo switch on the sterring column grounds a relay to activate it and cause the switch to hi-beam. With Hi-beams on the steering column switch would loose the ground while turning the sterring wheel. The lights would shift to low-beam and back to hi-beam several times BUT looks as is they were going on and off. I run a new wire from the top of the steering column to a new ground to provide a ground path. The problem was cured.
