Question about Chevrolet Astro
How do you check this ground from distributer ive replaced coil pack sveral times and now it wont fire i believe a ground problem...need help
Voltage drop testing will show power or ground circuit problem .
Also looking at a wiring diagram to see which ground point distributor is attached too. Free wiring diagram here http://www.bbbind.com/free-tsb/ Enter vehicle info. Year , make , model etc.... Under system click on engine , then under subsystem click on fuel controls . Click the search button then the blue link . Looking at the diagram ,i don't a ground for the distributor . Battery voltage supply to the coil , ground side goes to the ICM - ignition control module . You pulled the coil wire to the distributor an checked for spark ? No spark , ICM or crank sensor could be the problem.

it is located on the top of the engine in the piping that supplies fuel to the injectors, you will need a GM fuel press test gage to check it.
