Question about 1994 Chevrolet S-10 Blazer
It all started when my fuel pump went bad. R/R pump and filter. Started running very rough again. R/R plugs, dist. cap, button, TPS, Coil, and new computer. Did not change. it is real bad when idling. Sounds like it is skipping or flooding out. Checked all plugs an wires, all good. OBD1 will not comunicate. Can not get codes. Fuel milage sucks!! Maybe 12 mpg. I was told that if the intake temp. sensor goes bad it defaults back to -40 degrees and floods the intake with fuel. Problem is, I try to look up intake temp. sensor for 1994 chevy blazer 2wheel drive with the 4.3 vortec I get no results. What is the problem???
If you cant connect to the PCU I would start there, check every single fuse, and grounds for the computer, If they are all good test with a know good computer!
