Allen,
What kind of starter do you have in your truck? Is it the stomp style or has it been changed to a key actuated/solenoid style.
Do you have a multi-meter or volt meter in your toolbox?
You indicated you don't think the plugs are getting enough poop to start the truck. Will the truck start? Did the truck start? Has the truck run?
I don't want to hijack clems thread, should we go to one of your other post locations???
