Re: Gettin fire and i think im gettin fuel but my truck...
Shoot some carb cleaner into the intake ( or through a vacuum port) and try to start. If it will run for a second or two then you have a fuel delivery problem. Report back.

you said you repl dist cap that means you don't have a crank sensor you have electronic ing module. remove your elec ing module have it tested most auto parts stores could test your module, or check your coil at the neg terminal. should have power. if not you lost your primary volt from your batt.your secondary power is coming from your electronic ing module from the module to the pos terminal on the coil, when the eng cranks,from the coil to the dist cap , from the dist cap center to the rotor then out to the plugs,this all happen pervided the timing belt or timing chain is ok. the cumbustion chainber needs 3 things , thats fuel, air, and spark.
Since it don't fire, you need to check your spark plugs/coils, wires, distributor/coil pack, dist.cap, rotor, cam sensor, crank sensor. It may be the computer but that is last possibility. Each one of these effect the fire to the engine. You need to test what you can. It could be anyone of them.
You have spark on the coil wire but not coming from the cap. You replaced the cap right. Did you replace the rotor too. Sometimes the rotor burn in the center and the spark goes right thru it in to the distributor shaft.
1/ Have you fitted the spark plug leads in the proper firing order.
2/ Look inside the top of distributor Top (this is not the first time a new distributer cap has very small crack) or the rotor arm is fitting the cap properly. Hope this helps Best Wishes, Malcolm Campbell.
