When you changed the firing order did you pull and reset the distributor? The firing order was probably not correct because the distributor was not put in correctly. So what you need to do is bring the truck up to TDC with the crank pulley on TDC and the number cylinder to the top and see where the rotor points is it at number one cylinder?

You have one of two options here put the firing order back or follow my previous instructions to make sure the timing marks all line up.
