OK only other thing you need is what is the BATTERY voltage when cranking?
Or hook your meter to the same place above, and instead of ground, to battery plus. Crank and read. This will give you the voltage drop in that circuit.
if it won't start/ run with 10.89 I'm quickly out of ideas. You might try the test several times, maybe there's an intermittent in the IGN2 circuit
If you want give me a call. Send a PM I'll give you my no.
