87 2wd 1/2 ton 305 tbi
I checked the timing today and as per instructions , I disconnected the EST connector before I started. Disconnecting that plug should have been reason enough for thecheck light to come on[/It did not
I plug the connector back together and the light didnt even come on when the key switch was turned to the on positiom
I tried to jump the connector under the dash and that didnt work either
The ecm and ignition fuses look good, are there any other fuses or links that power up the computer?
