fuels good that im positive off. spark should be good but not poitive. all vaccum lines are good and manifold bolts are tight. it runs for about 2 seconds then dies

Re: 3.1 ecm need help.
did you check the ecm for any codes?...if it was vats it wouldnt do anything so ur good on that,might be weak spark,the gas is extinguishing the spark and causing it to die maybe,,pull all plugs,check color and wear,,if thy r not bad, gap to 45 thousandths (.045) and be sure to check the tbi bolts but that would be a bad leak to only run 3 seconds,u would hear that maybe if some one else turned the key while u listened.Please update us on what u did..
