Partial progress?
I replaced the ignition coil module with a Delphi brand unit even though it was sold as an ac delco. But then the one I took out was a Delphi (probably original).
So now I can hear the fuel pump rev up and get a strong spray at the schrader valve. Still turns over but...

I just checked the voltage between the black and red wires on the connector to the icm. I got 12.1 v. This suggests that the black is connected to battery ground. I don’t see any other ground connections from the icm or the coil module.
Question: could a faulty coil module prevent the...
Fully charged the battery from 38% to 100% still no start. I don’t hear the fuel pump but the engine turns over. Probably no spark since I had someone spray starter fluid into the throttle body when I turned the key.
Connector voltage
As a follow up, I tested the voltages at the input to the ignition control module with the ignition key in the on position. Looking at the connector with the release mechanism at the top, there are 5 positions along the top row and 4 along the bottom. Numbering from...
My 2006 cobalt LT 2.2L started running rough a couple of weeks ago. So I cleaned the throttle body - didn’t help. At this point I got 2 engine codes - P0106 map sensor and P0300 random misfire. I put in a new MAP sensor (standard parts brand) - didn’t help and I put the original back in...
