Hi Guys, 86 Alfa Graduate Spider, 30k miles.
Just yesterday I turned the key, starts cranking, nothing.
Check some wires, turn the key nothing, keeps cranking.
Wait a few minutes, turn the key, fires right up.
Drive 20 mins.
Let it sit 2 hours, won't fire. Plenty of cranking, but nothing. Check everything, nothing. I leave it for another hour, fires right up.
Here's what's been replaced in the last year:
Plugs (checked the gap to try to diagnose this)
Wires
Distributor Cap/Rotor (yesterday)
Ignition Coil
Here's what I checked:
-Pulled a plug out, no spark
-Pulled a different plug out, no spark
-Tried to get the coil hot wire to spark by laying it near the top of the motor, no luck
Well, it's running now, but I know the next time it fails will be the time that i'm far from home. Also, it never dies while running. It only happens on startup.
My questions are:
What could this be?
Some other ignition component?
Next time it happens, what can I check?
If i put a multimeter on the two sideposts of the coil, what should it show while cranking?
Thanks in advance for all your help. This board has been very helpful to me so far!
