Still have ignition problem!!!

93 YJ 2.5ltr.
Hi again, I posted a problem with my ignition system a few weeks ago. I’m still having a problem getting ignition. I have no ignition or code lights on the dash. I’ve checked the connections at the start relay and I have 12v at contact 30. I have no voltage at 86 or 87 with ignition switched on, 85 is grounded. Does this indicate a problem with the ECM, have changed the ASD relay. I have had the battery disconnected for three months. Would this have affected the ECM. Battery is fully charged and showing 12.5v. Engine turns over fast enough when key is turned to start. Any suggestions would be very
appreciated.

All these relays are a mystery to me.. lol. it amazes me that nothing can be wrong with you engine and it won't start because of some switch.
Best help I could give is find the component you have power going to, but not coming out of. That should be your culprit, and the part you replace. sounds like you should be looking at that 86 and 87. see if power is going to it, if not then back track to the component before it and see if there is power going to, and out of it. your bad part should have power to, but not out. test wires not the component for voltage.
