Thanks for the replys. i have ruled out CTS because it is stubborn to start in all temps but especially warm. When warm, and when I say warm...barely warm like running for 5 minutes at idle warm.
Ruled out fuel pump and vapor lock because there is no possible way gas is vaporizing right now. Temps in Colorado are barely above freezing. I have a Walbro high flow pump FYI.
Its gotta be ignition. Tests have shown irregular or non existent ignition pulses into ignitor/coil. Again though, the crazy thing....it runs like a champ once it starts.
Looking for shorts now. Argh.
Be careful when ruling out the CTS. 0 degrees and 32 degrees is a big difference, I bet, and a faulty CTS could be telling the computer that it's 100 degrees, or 0 degrees, or whatever. The computer would use that faulty information for fuel enrichment on start. I would imagine it would impact ignition as well.
Can you jump the starter with a screwdriver? In my head, at least, that's a way of skipping whatever the computer was doing on startup. It worked for me until I addressed the real problem.
