heres teh story.. 2 weeks ago.. driving around town my truck would not start every now and then.. i would go out and wiggle the wire going from the coil to distributer... then last week it stalled and would not start anymore.. so i thought it was the coil.. got the coil.. still didnt start.. then i got a distributer cap, rotor, and still no start.. so i picked up a used igniter off ebay.. and it started up first thing... then after about 1-2 minutes when i was closing the hood.. the truck shut down.. so i am back at square 1.. any advice??? i ripped apart the harness a lil and noticed 1 wire was spliced going to the coil and igniter.. anything will help. thanks guys
