My 91 gmc vandura 3500 skipping/stalling/bogging

Ok for a few months now my 91 gmc vandura 3500 would crank fine in the mornings. when i go to back up it would stal for 2 or 3 secs and then run fine and no problems the rest of the day. a week ago it did that skip/stall but this time never stopped. Now its running like it just cant go..i can press the gas and it will shutter and skip then kick in for a few secs then start skipping again and bogging.. i have just done a tune up with new plugs, wires, distributor cap, rotor botton, new vaccum lines, air filter and fuel filter ... that where i am now ?

1995 gmc sierra bogging when wet


Check your coil for cracks or signs of corrosion. If you instead have a distributor cap, do the same. If it all looks okay, start the vehicle and pop the hood. Get a water bottle or something to spray water with and start getting the wires and coil and distributor wet until the truck stalls. Make sure to do it slowly so you can tell what part you soaked that caused the truck to stall.

Need a wireing diagram


Ido not see a solution posted...but will offer thar your input voltage to the coil is low when cranking the engine...but when the key is restored to the run position, voltage is almost enough to fire a spark plug. Put a dc voltmeter on the 12 volt input terminal of the coil and confirm. If input voltage is ok then replace coil.

I HAVE A 1986 GMC VANDURA 3500 CARGO VAN,ALWAYS TURNS ON WITH NO PROBLEM,OK HERES THE THING.MY GAS METER WENT OUT RECENTLY SO I DROVE IT AROUND ALL WEEK BASICLY JUST TRYING TO EMPTY THE TANK SO I CAN FILL...


If the fuel level is very low and the van is not level it's not going to start even if the pump is good.
When you turn the key to on you should hear a fuel pump noise for 2 to 3 seconds if the key has been off for at least 10 seconds,and when cranking or the engine is running the pump runs because there's oil pressure sending power to the pump.
Have someone listen back at the tank.No Noise?then it might be time for a fuel pump.
Your fuel filter may be just ahead of the rear axle on the passenger side under the van.
But.....if your gas gauge went out and now your pump quit,maybe the wiring back at the tank is corroded?

I have found the most common part failure issue with the ignition system is the crank sensor, also called by some the TDC sensor.

next time it happens try spraying water in mist form around the throttle body if it bogs, replace the throttle body gasket. if it doesn't bog you may have a bad wire wait until dark start the vehicle have someone feed the fuel very slowly and watch for arching from a wire it will be easy to see when it is dark, replace that wire.

Gmc vandura 1996, 3500 running rich


There could be all kinds of reasons your vehicle runs rich. It should be fuel injected not carborated. It could have a bad injector, bad air filter, o2 sensors etc. Have it scaned for the reason.
