Not startig

Hey Mario-Sorry to hear about your S10 problems. So when you try to start it, does it just turn over and over? Does it make a clicking sound? Do all your lights work? If its the fuel filter a good whack on the fuel tank with a rubber mallet, or a light bang with a hammer will usually get it started (if that works then you know its the fuel filter). When you turn the key to ACC (meaning turning the key forward one click to turn on the accessories i.e. the radio, heather, and dash lights come on but not start it), do you hear the fuel pump priming itself? It sounds like a quiet hum from the back of the rig that lasts about 2-3 seconds? Ill follow your thread to hear back from you. With more information I can diagnose your problems more accurately. Best of luck man!

Have you checked for spark?, and how do you know it is not the fuel pump? Fuel pressure on that one is 9 to 13 lbs. at the TBI
