Please Help!! No Spark to Distributor

I need some desperate help. I have a 1982 Ford F-250 with a 5.8 liter engine. I'm not getting spark to the distributor. I changed the pick-up in the distributor, but that did'nt work. Then, I changed the coil, and that did'nt work. There's no spark going from the coil to the distributor. Can someone please help?

Its probably the ignition module. That truck probably has the duraspark 11 system. If it does, the ignition module is on the fenderwell. If its the TFI system, its mounted on the distributor. Go to autozones website, look under repair guides. find your system, and theyll have details on how to trouble shoot it. Or you can just put one on it. Save your old pickup and coil, theres probably nothing wrong with them. Good luck.
