MAKE SURE THAT YOU CHECK OUT ALL OF THE WIRES GOING TO AND FROM THE COIL AND IF THEY ARE ALL HOOK UP TAKE THE COIL TO THE PARTS HOUSE AND HAVE THEM CHECK IT OUT FOR YOU
First of all let's explain how the spark gets to the plugs. There is a crankshaft position sensor and a cam sensor. They are what determines when to fire the coils and injectors. The crank sensor is located on the passenger side on top of the bellhousing, the cam sensor is the pickup plate in the distributor. As the engin turns the send refernece pulses to the computer which grounds and ungrounds the ignition coil causing it to discharge and send voltager from the secondary coil wire to the center tower in the distributor cap. The rotor button recieves the voltage and distributes it to the 6 towers (1 for each cylinder) If you say you're getting spark from the rotor that tells me the primary side of the ignition system is working, and the secondary side is working into the distributor cap. I'd check for spark out of the plug wires at the plugs. Pull a wire and insert a #2 phillips screwdriver into it, hol the shaft of the screwdriver aprox 1/8"(no more) from the exaust manifold and observe the spark as someone turns over the engine. You should see a nice blue spark. If theres spark, spray a little gum cutter in the throttle body an crank it, if it fires you have a fuel problem. Install a fuel pressure gauge on the schrader valve on the fuel rail and observe it as you crank it. If theres no fuel pressure maks sure there's fuel in the tank, if so climb underneath and beat on the bottom of the tank with a rubber hammer, the pump may be going bad, sometimes you can jar them and make them run.
if truck has a ceramic ballist resistor near and connected to coil this could be problem or the crk posistion sensor could be too, i would change ballast first if you have on your truck appx cost $10
There is a sensor that located on the right side of trans. that goes into bellhousing up close to the engine, it runs off the flywheel i think its the crank sensor but i'am not sure, i had a simmler problem with one i was working on, replaced that and it ran.
