See if you have spark and injector pulse.

While cranking you can see fuel squirting into the throttle body.What could have happened to the spark?I have checked the fuses.Is the only fuse panel under the steering colum?

Only things that would make it not have spark would be coil, or ignition module, or the ECM. If you just want to through parts at it I would do the module first.

Ckeck B+ to the coil. Check the pick up coil resistance 800 ohms is average. If that checks out ok check the coil primary and secondary resistance. If ok replace the ignition module.

Glad to hear you got it solved, my truck would start and run fine sometimes and sometimes it would turn over but not start, had no spark..replaced coil with an accel supercoil, didn't fix it, replaced cap, rotor, and ignition module...didn't fix it..replaced ignition switch..fixed it  ::)

Joseph- to answer one of your questions- there is only one fuse panel.
