you should be able check fuel pressure at shredder valve and turn key on and off 3 times should be good enough, id check to make sure you have good oil pressure ,then make sure oil pressure switch isn't at fault

Most likely you snapped the 4WD chain in the transfer case. Put it in 4WD go in reverse with the wheel turned if the vehicle does this smoothly than your 4WD is not engaged.

I'm not sure of vin? My info shows oil pressure switch in parallel with fuel pump relay, so if that switch is functional and has voltage, once you crank it enough to bring up oil pressure, the pump should run even without the relay. The voltage for load side of relay and oil pressure switch comes from ecm B fuse. The voltage for control side of fuel pump relay comes from pcm. Any other issues besides fuel? Engine cranking do you have spark at the plugs and fuel injector pulse? If your missing the last two, have to check for rpm signal.

Idle is controlled by Idle Air Control (IAC) and the Throttle Position Sensor (TPS). Check these, and then the EGR valve.

Check the actuator motor on the heater and make sure the heater doors are fully opening and closing to direct the heat or ac. It is inside on the heater box in the end close to the driver side.

There should be a Service Parts Identification sticker in the glove box. These numbers are used to identify what drive line parts were fitted to you vehicle.

You remove the cluster and take it in to your local GM dealership. They will send it off and get it repaired. Usually takes a week to a week and a half.

It should have an idle air control valve which lets air into the intake to control the idle speed. The valve could be faulty, or dirty, or the throttle body could be dirty. The computer opens and closes the valve to regulate idle speed.

The fuse block is located to the left of the steering column about 1/2 way down the kick panel, if you look uo, you will see it.

Sounds like you fuel pump may be going out or your line is clogged. Change the inline filter..if that does not do it ..have the fuel pressure tested...good luck..

probably rear cable in shoes froze remove back wheels and cut cable then beat on drums to get freed up you might need new back brakes and cables you can try pulling on cable while hitting drum before you cut them

Sounds like u may of forgot a vacume line a good way to find a vacume leak is to start car take a can of carb cleaner and spray it around intake and vacume lines if there's a leak motor will race as long as u keep spraing

Vacuum issue at canister, etc

vacuum issue

detrim the dash panel, snaps around the perimeter, a few bolts underneath, I think...when istr. panel is visible, you will see the surrounding mounting screws, remove, pull cluster forward, disconnect electrical connectors....reverse to install

Gently pry off the trim bezel on the outside of the dash to detach the clips. You may have to tilt the steering wheel down all the way to get the bezel out of the way. Once it is out of the way, you can see the screws holding the instrument cluster in place.

Hi Braxton, If any of the fuses keeps blowing there must be a short circuit in the system. Trace the problem and fix it or a fire could result. As the problem is related to a single circuit you shoud be able to trace it by starting with the unit it's self and trcing the power cable backwards from there. Regards John
