Hello all. I have a 91 S10 blazer with a fuel injected v6 that won't start. I drove It home last night with no problems and this morning It won't start. It will turn over, and start and sputter weakly then die right away. I changed the fuel filter to make sure there was no blockage there, and I think I can hear the fuel pump hum when I turn the key to on but i'm not
100% sure. One thing that I never noticed before was when i had the hood up with the key on there was some sort of module making a constant, light buzzing noise and there was an odd odor emanting from around the area. I'm kinda stumped. I'm hoping It's not the fuel pump as It's In the gas tank and thats too much for me to undertake. I'm thinking about changing the Oil pressure switch such thats cheap and easy to try first. Any ideas or input would be most welcome.thanks
