Had both the Starter and Alternator fail while I was out of work, so the truck has sat for a few months, I have some spare cash now and I'm trying to get it running again.

I replaced the following:
Starter, Alternator, Battery, Spark Plugs and Distributor cap.

Cranks fine, but acts as if there's no spark, it wont even fire up/react to starting fluid? I pulled the plugs and they showed signs of firing and do have a good spark, so I'm wondering if I have the firing order wrong? I don't have a Haynes/Chiltons manual so I can't double check.
