I have a 95 jimmy 4.3 L v6 I have just put new head gaskets on it and now when I try to start it ,It will not start unless I use starting fluid , Then it will start but will only run for a few seconds and then dies and it will not restart again unless I use starting fluid again. I'm getting gas to fuel relief valve and I'm getting fuel to spray from relief valve when motor is cranked over. I'm also getting fire from coil wire to cap and from cap to spark plugs. Can anyone help me out here please not sure what to look for from here?
