truck just shut off while driving down the highway and would not start. i checked and it sounds like the fuel pump is turning on, the fuel pump relay fuse and fuel filter are new, the electrical and battery seem fine it just wont turn over, i also have recently replaced spark plugs, wires, dist cap, rotor, coil, and ignition module (this was all before this problem) Almost forgot to mention i have had a service engine light turn on with Code 32 could this be a probem? Thanks for any suggestions.
