Welcome to the forum Grumy,
Let's get some more info first. What engine do you have?

Go ahead and have it scanned, you could have pending codes. If no codes or pending codes start by changing the fuel filter.

Changed fuel filter,coil pack,plugs,wires,and no change. Today I try to start the truck and it would not start. crank a couple of times seems to have compression lock ,pull the plugs found them wet,smells like dexcool antifreeze.I decide to check oil,pull the dip stick oil level fine,removed oil cap,found antifreeze on the cap and in the filler neck.I guess I have a couple of blown head gaskets
