Question about 1993 Chevrolet C1500
Firing order, damper timing marker identification which one, set to what degree, do you have to unplug anything to dissconect ecm from controlling timing. need step by step help please.
If it is the same as the 4.3 in my 93 s-10 blazer the firing order is 1,2,3,4,5,6 with 1 being front dead center of ditributor(closest to intake manifold) if it is located at rear of engine. As you're standing in front of vehicle facing engine front right cylinder is #1 middle is #3 rear is #5. On left side #2 is front #4 is middle and #6 is rear. On my Blazer I have to disconnect the EST wire which is located inside the vehicle just below heater housing on passenger side(at top of floor carpet) in order to set timing. It is a single wire connection. Don't know if it is same location in the 1500. There should be a lable on top of the radiator area with the degree to set timing at. It is 0* for the s-10. If you have a parts store handy and have a few dollars available pick up a Chiltons soft cover repair manual for you vehicle. I got one for mine and it has been really useful. Hope all of this is helpful. I'll check to see if you get it set. KS
