Question about 1998 GMC Sonoma
I am installing a tach in my sonoma and i need to know which ignition wire to plug into.
SOURCE: 1996 Gmc sonoma
there could be several possibilities, first did you change the fuel filter? most often times a partially plugged fuel filter will cause the sputtering. plugged fuel filters generally lead to the failure of the fuel pump. if you have a fuel injected vehicle the injector themselves can fail, this happens often especially if regular maintenance doesn't happen. i always use an injector cleaner additive when i fill up each time. a common symptom of sputtering is a plugged catalayic converter. the engine needs to breath to run right. also check the airfilter this is important for the engine to breath as well as proper fuel air mixture. if the engine senses a loss of power due to low fuel air mixture it will try to pump more fuel then it should therefore it's basically flooding itself. try these basic fixes first. if this doesn't solve the problem then post back with more detail and i will try a different approach.. please rate this thanks.

2.2L Engine remove protective shields as needed then remove front exhaust pipe. Remove the brace from the engine to the clutch housing, then disconnect starter wiring. 4.3L Engine 2 wheel drive just remove the right front tire and you will have access to the wiring. 4.3L Engine 4 wheel drive you must remove the differential carrier shield if equipped then remove the starter bolts and rotate the starter to get access to the wiring. Good Luck.

remove the rear shaft from a 1990 full size gmc van (g-van) make sure the one you select has the scew on sleeve at the front of the rear section of the shaft
this will be the right lenght
take the rear yolk off your old shaft cut of the ball socket now get the same u-joint your truck calls for and mount the rear yolk (the section of the shaft that bolts to your rear end) to the new shaft
this works ive done it
you eliminate 2 of the 4 u-joints and lighten up your shaft this releives strain on you tranny and rear end when these u-joints and ball bearings fail they cause the vibrations which ruin the rest of your drive train also you gain 10hp
i spent 300 bucks rebuilding the OEM shaft and got no where so for 25 bucks i did this

if you have access to a scan tool, hook it up and look at your live data. check for crankshaft and camshaft sensor reference. if one of these (more specifically crank) if malfunctioning, the ignition and injection will not function.
