Bad news guys.
She still won't start, even with the new battery.
She fired up for just a brief second then died out again. Its almost like there was a small amount of fuel in the line. Then the engine just faded out and died. This happened twice the other day when this mystery no start began.
So now I have a new battery.
I also did a questionable job on the RCM re-solder.
I cleaned the contact on the RCM switch closest to the firewall as described earlier in this thread. Hopefully that may abate the P1401(0401?) code I got right before all this started.
Now what? Crankshaft sensor? Secondary air injection pump? Fuel pump?
