    I have an 87 K5 blazer, wnt to start it yesterday and crank but no start, thought it might be fuel filter so changed it out. Noticed the ecmb fues was blown replaced it and it blew as soon as i turned the ignition on. changed out the fuel pump thinking that might be the issue. Still no start...
