Question about 1983 Chevrolet Silverado
Engine was running very rough, changed wires, plugs, dist cap and rotor. Wired exactly by firing order diagram but engine will not start at all. Backfires through the carb and will only start when distributor is turned all the way to the stop ( vacuum advance hits manifold) doubled checked pig wiring (firing order 18436572 with distributor wiring clockwise
Sounds like you have the firing order right but your off on the #1 on the distributer. Every time you get an explosion coming from the carb its misfiring. Find the #1 on dist and continue with firing order

Bring #1 cylinder up on T.D.C.,(top dead center) firing stroke ,remove #1 plug place a finger over the hole when the air from the cylinder pushes the finger off of the hole, check timming marks make sure they are lined up, remove distributor cap see where rotor is pointing this should be #1, then just follow firing order around the cap in indicated direction
hope this helps
