Need to know which engine you have.
Your truck has two coil packs. one on each side of the truck. I changed mine twice on my 99 expedition. I dont know the exact definition of the coil pack, but i know that they are related to the sparkplug and it's wires, and when they go bad they can cause a misfire with the sparkplugs. If you need to change them send me a message i can tell you how.
Need to know if it is a 4+2 or a 4+4.
Your sparkplug won't spark means that is too old already and it is worn out or it was wet or something and you need to change that one.
Need oil change or oil pump weak or oil pressure sending unit not reading properly.
You need a ratchet with an extension and a sparkplug socket to remove it.If they don't pass inspection you should replace them,but if they look okay you can clean them.You clean the sparkplug with a wire brush and a solvent like brake parts cleaner.
