5.9 Magnum help needed

Since you get spark, it isn't the crank or cam sensor (in distributor). Next time, carry a can of starter fluid like I do. If it runs on that you know you have a fuel delivery problem and not bad compression - broken timing belt or such (yours has a chain anyway). You have quick releases on your fuel lines to pop them off without a tool. However, they are often hard to remove if it has been a while and the plastic releases are often brittle and break, at least they do that to me in the junkyard when I rob Magnum parts.
