B2600i Mazdawg wont start

Hey guys here i was getting ready to finish putting my truck together and I bled the brakes and clutch and to this point my truck had been starting up fine. The next day the truck just cranks but wont fire up, I check for spark my unpluging the spark plug cable and check for spark and theres no spark so I dont know if its either the coil or something inside the distributor call the ingniter or something. Anyway to chekc the coil or basically anything to get me going in starting up my truck.

I believe you can check the coil by a test meter to check the volts going in and out of it, if not the pick up in the dist. might be gone.

when welding on my old b2600i, i killed my coil/thing next to the coil. I can't remember whats its called. It ran fine till i took it down for a bit to air bag the front. I had the battery disconnected also, so i don't know if its what caused it, but thats my guess. I replaced mine with a MSD 6AL and a ford coil, works fine, but gets bad gas millage. Also on the B2600I, the computers go out ALL the time, i've fixed a few, you have to take it appart and see if the compasitor is leaking or looks like it just ate at a all you can eat place.
