Hi, I got the main relay checks done as per the diagram pictures you sent.
Battery voltage is present where it should be. At the relay and wiring harness plug both shows B+ voltage.
The relay clicks and I can feel it as well in my hand when turning the key to run position.
I fallowed the flow (yes-no) chart twice and got the same results.
Poor connections at A12 and A13-OR-ECM and it's circuit.
I inspected the plug ends and carefully, bent-let's-say, the connections for A12 and A13 to ensure a tight connection.
No corrosion visible in any way.
Upon repeating the flow chart test, I got the same results.
."Check ECM circuit".
I'm going to check all grounds and battery positive voltage where I can find them.
B+ at ignitor
ECM pin #A1 for B+
ECM grounds at B1--B2--and--B14
grounds under hood for B+ and any voltage drops.
When I get some real numbers I'll respond. Thanks for the help.
I'm still thrown by the O/D light flashing though.
