Nope, no resolution yet.
Too hot outside to fool around with finding a fix.
The "no start on first crank" appears in the morning also . .at first
start. We are in a heat wave and I'm wondering if the problem is
ambient temperature related.
If I crank long enough - 3 to 4 seconds, I'll get a cough or two out
of the engine. Key off and on and crank, and she starts right off.
I'm wondering if the cold start valve shuts off after a second or two
at warm temperatures. Shutting ignition off and on recycles the cold
start valve for another shot of fuel - and the engine now starts.
Which indicates an air leak in the intake system. Too lean a mix for
starting, but not lean enough for running.
