1/2 ton V6 4.3 liter? my truck will not start unless I prime it with gas every time first....once I do that it runs great. It doesnt need a fuel pump or fuel filter....could the ECM be bad maybe? Someone tried to tell me that it could need the fuel injectors replaced....but I dont believe that is the problem....wouldnt it not even run if they were bad? I took it to a shop who tried to tell me the fuel injectors were plugged up and charged me $130 to flush them....and the problem still exists. My Chilton manual tells me that the Electronic control module tells the injectors to squirt the fuel upon starting so if it were bad couldnt that be my problem??? Please advise....!!!

Can't believe the mechanic didn't fix it; a person should be able to go back and say 'you were wrong' and fix it free! But alas, no,so hubby says could be ecm for sure, but do you hear the fuel pump kick on when ignition is turned to 'on' position? Mine went out in my 91 blazer. Pump may not initially have the pressure in inject gas, but once it's started, there's enough to keep it running. ECM is usually located under the hood along wheel well. Chilton book should show you diagram of instruments under the hood. Good luck! Hope you get it fixed soon. I was stranded in a small town bar while local mechanic replaced my fuel pump and cost me around $300!
