Check engine light flashing
I replaced fuel pump, filter, plugs and wires, ignition coil, new battery, tires, on 1996 chevy blazer 4.3 liter, no codes read but running rough with check engine light flashing, I'm lost on what next, please any ideas?

A flashing light is more serious than one that is just on. Something is usually wrong in the emission system and could damage the catalytic converter then being more expensive to repair. Have it checked quickly.

at the least get the code read by a punk at auto zone. if you have $50-100 get you a reader that can do “live readings” and see what its doing based on the codes and live readings. codes are normally emmisions related. live readings will tell you the actual overall health of your engine based upon what it says at idle, then at 2500rpm and so on..
