I just got a new fuel pump, plugs and wires and it's running like a champ. Well today I go out to start the blazer and... Nothing. Just the electrics come on. It won't even crank. My battery is good and I have no other electrical problems. At this point I have no idea what it could be. Is it possible the pump was put in wrong? The mechanic I had do it was trusted and a reputable shop. With the new plugs and wires and the new fuel pump I am at a loss as to why it won't start or even crank. Any suggestions?

 

If it's not cranking then you have a problem with starter or your not getting power to the starter. Check fuses and wires good luck.
