[lenmoreno]

changed out spark plugs and wires,
one at a time ...of course.
now truck has major problems getting started,
could it be a timing issue now

Check your wire leads to the ICM since you were working on your ignition system. Start with that and also try replacing your fuel filter also, doesn't hurt to cover all the bases at this point. Was the right spark plugs used with the proper gap???

Good luck and keep us posted.

did use the correct plugs,
and gap was .035
fuel filter will be changed ASAP, like today
