In another thread, computer died. I had the intake I made for a 90 model 16 years ago the computer went bad for injectors 1/3. I put it on this 93, but the truck decided to stop firing (wired coil to battery, removed switch from circuit), computer bit the bullet I figured. I had everything hooked up on the intake like I did the 90.
I decided to lose the bot completely. I got a 2200 distributor. It is 0.278 longer than 2600 distributor, o.d. is the same. Machined it down, reassembled it. Put it in and grounded the - coil, figuring the circuit went through the tach to ground and I would wire in the tach later,and remove this ground. Mazdatweak2 in a reply with the simple statement about the coil ground, "something about that ain't right" hit me.
The tach grounds through the module just like the coil (I was thinking it received power from this side). The tach is an unrelated, related circuit. With the coil grounded, the module was along for the ride, nothing to do! I realized circuit was lik pre-bot GM's. Put it together without grounding the coil, got it to start. Now the carb that has rested on a shelf for 16 years seems to need a little love. I feel really dumb, mazda is just a truck, after the bot is gone.
