Ignition Trobuleshooting

did you change the fuel filter?I had this problem with my Duster when I first got it.There was chunks of old rubber hose that connects the fuel line to the fuel tank that made its way to the fuel pump and clogged it,and made it to the fuel filter and clogged it as well.If it sounds like it "almost fires",then you are getting spark.Sounds like it might be a fuel issue.You might also want to pull the sending unit and see if the sock is deteriorating or plugged.good luck
