Pull all the plug wires from the plugs. Soak plug and wire end with wd40. Do one at a time.

To test for spark (what were you holding when you got zapped?), use a phead screw driver. Pull the coil wire from the dizzy, insert the phead into the wire, and crank the truck, holding the shaft of the screwdriver a tad under 1/4" from the coil bracket. You should see a hot blue white spark. Repeat for each plug wire. If all are sparking, you have water in the fuel. There's a drain plug on the tank. Remove and drain around a pint into a clear jar. Look for water on the bottom.

The smell test at the tailpipe usually means you have spark, but it's not getting to the plugs for some reason. The ecu will not inject fuel unless it sees a spark signal at the coil - terminal. If you have total spark failure, no fuel gets injected.

Listen at the open gas filler as the key is turned from off to on. The fuel pump should run for one second or so.
