Computer controlled, you no longer have the ability to manually adjust it.

no, it is already timed. timing on a DIS is controlled by a timing wheel on the crankshaft. there is nothing to move/vary from engine to engine, like a cap & rotor, so, the timing can be fixed/unadjustable.

ok, warm day and had about 45 min of daylight.... i tested the wires between the 5 pin DIS connector and the ECM plugs. all checked out fine. checked the power and ground on the 2 pin, all good. i removed the crank sensor wiring to wind together in the correct fashion i heard about from joe. well see what happens....anyone else have any input? if that proves nothing, then im down to replacing the ICM.
remember, no spark and the tach needle isnt moving. so its not getting something to send out....
crank sensor is going to be replaced too.

ok, i just made a corrected crank prosition sensor wire (wires twisted together) and i am still getting no spark. tach needle isnt moving during cranking either. ICM possibly?

If your crank sensor is good and you have verified the wiring between the crank sensor and ignition module; and you have verified the ICM is getting power and ground where it needs them; then yes, it could be a bad ICM.

I'm sorry if this was covered before, but I couldn't find it.
I am making an adaptor wire interface to be able to plug in the factory Fiero wire harness with minimal modification to the Fiero. I have the Wire harness from the 7730 and the pin side of the Fiero computer ('87 GT). The I see the pin connection listed as "Pin A1 move to Pin BA11". The Fiero side pins are obvious. There are 4 banks of pins... A,B,C, and D. All of the pins are numbered. simple. The pins on the 7730 wire harness are labeled as 6 banks A,B,C,D,E, (and I presume but it is not marked) F. Which pin is "BA11"? is that the one in pin bank "A" and PIN #11? What does the "B" in front of it mean? Is that the connector (there are 3 which could correspond to B and G and Secondary wire harness)?
So in summary.... What does the "B" and the "G" for the 7730 Pin location mean?
Thank you.
