Check the coil if the coil or coil packs r dead then u won't have spark if it has the single coil it will be located on top of the dist. Cap
Ok replaced the coil and that got it running but have another problem I was trying to fix before the coil went out. Truck sits overnight or 1-2 hrs it cranks fine but run it five minutes and cut it off and try to crank it back up it floods. Smell gas and have to hold pedal down to get it to crank. Runs a lil rough for a second then it's fine. I was told it could be a MAP sensor and replaced it when I replaced the coil.
