    Default 95 S10 4.6 TBI, ECM blew


    Hello, New to the forums and wondering if anyone could help me narrow down my issue. I have a 95 s10 4.3 TBI 2wd. The ECM Fuse recently blew, Ever since replacing the fuse my truck idles very rough from 300-1,200 RPM and sometimes gets stuck at RPMS. I have to floor it in order for it to react, then it will jump to about 5k and idle back down. If I try to drive it the ECM blows randomly I have went through 3 fuses attempting so.

    I have never had this issue until that ECM fuse blew. The only 3 things that specific ECM runs/protects is the Computer, Oil Pressure Reg and Fuel pump (So I been told). I have replaced the computer, Unplugged the Oil press reg made no difference. I replaced mass air sensor, Air/Fuel Sensor, EGR Valve gasket, Fuel Filter Cheap things in hopes it would fix it but same results. I'm thinking it's the fuel pump but, I am no mechanic and would like some other opinions before replacing anything else.

    Thanks in advance!
