Tune up

I think that you may have mis-routed the ignition wires, which can cause the sounds that you describe. here is a link where you pay a little to get the proper wiring instructions for you ignition wires. http://bit.ly/mitchell_repair_manuals_online

Update: I went to the site dandd suggested and re-routed my wires. The truck started up great but then the sound came back again and I started to smell a little gas fumes. Would the coil cause this or is it something else?
