Sounds like an electrical problem first you will need a test light if you do not have one any parts store will carry these you can purchase once you have it go under youre hood find where the wire from the battery leads to the a soleanoid its round should be on or near either the right or the left wheel well it has two metal posts on it take one wire from the test light and attach it to one of them then take the ground wire on the test light and clip it to a piece of metal make sure it has no grease or dirt on the metal or it wont work then take the ponted end of the test light and touch one of the metal posts if it lights up you have current or power there if so then go in the cab where you insert youre ignition key behind it youll see another set of wires there with metal posts repeat the same process and again if it lights up you have current or power there if so check for lose or broken wires if they check out then you have a bad soleanoid

Wiring diagram for 1986 gmc sierra 2500?

Other than POSSIBLY some gauge sending units, it should be reasonably simple. You could most likely re-use the temperature sender and the oil pressure switch.

The alternator should plug in the same. The starter wires should hook up the same. The ignition, providing it's electronic/HEI (big distributor cap with built in ignition coil in the top) will simply hook up to the wire that formally sent power to the injector pump shut off solenoid on the 6.2.

You won't, or shouldn't have to use ANY of the glow plug or cold advance/high idle wiring. The cold advance wiring should have 2 connectors 'pig tailed' together that was on top, towards the front of the 6.2.

Hope this helps.

This is only my personal opinion, but unless there was some major mechanical problems with the 6.2, I would have left it in. I have an '85 GMC K2500 with the 6.2, 3.73 gears, and 'granny' 4 speed. It gets an average of 20 mpg and does everything I ask of it. Yes, it's not a super power house, (they weren't designed to be) but if I had a 350 gas engine I can guarantee I wouldn't be pulling the mpg's that I do with the 6.2. Plus I can burn WVO (waste vegetable oil) which is free.

Like I said, this is only my personal opinion.

The heater / ac in my 2006 GMC Sierra 2500HD has gone out several times. It has always been corrected by replacing the resistor. Replacing the resistor did not work this time. I have checked the fuses...

You have replaced the resistor and the blowwer is good and the fuses are good then i would say its in the switch or power to the switch, maybe at the ignition switch there a bad wire . sometimes the power wire going from ignition switch heats up and causes a bad connection, if you pull connector off the switch make sure the connector to ignition switch is not melted or burnt and also check blower control for the same, i would say that your blower is bad and drawing to much current if you have replaced a few resistors, i think maybe theres a fuse under the hood in the fuse /relay box that may be out or the connection at the switch or ignition is melted. hope this helps.

Looking for ignition switch in 93 gmc sierra

Tword the bottom of the steering colume. It will have a couple of connectors going to it and a couple of rods going to it from the igniton cylinder. IT is on top and not easy to get the bolts out of it. You will need to remove the close out pannel to even be able to see it.

1997 GMC Sierra Ignition Switch Replacement

take off the cover on the top and bottom of the steering column just behind the wheel. pop the tilt lever out simply just by grabbing it and give it a good tug. then once you have the new switch and you get in there your going to need an inverted torx socket to remove the small bolts that hold the switch to the column. do not move the gear on the new switch make sure it lines up exactly as the old one did!!!!!!!!!!!!
