Cold Mornings
My big gurl does't want to get up and go on cold mornings. I'm having issues first thing in the morning when the temp drops below 32F. After, it finally starts I'm fine for the rest of day. Drives fine and starts fine. Reminds me of an old carburetor car.
It cranks and cranks and cranks, maybe only after four and five cranking cycles will it finally start. After that I'm fine.
Any ideas what would cause this?

Interesting. Will try switching relays. Thanks.

Is there a cold start injector on these? My Mercedes 500SL had one. When it went out, same symptom...
You might also try connecting a jump to the battery on that first start, just to rule that out. I've had strange battery issues with seemingly good batteries.

Ironically, No faults. No stored or pending codes.
Maybe, unrelated, but worth mentioning; Sai pump kicks on for a second or two at red lights after the truck has been running at full operating temp. Then shortly after while still driving, ultra gage sometimes throws a "pending" P0420 (catalyst).
All four O2's are two years old
Y-pipe is also two years old. But, it's a Davco aftermarket. Unit. It has smaller diameter catalysts then stock. Which I assume work fine, but don't last as long as factory.
This is all the info I'm working with.

Update:
Something interesting happened today.
Ambient 61*F
Lunch time. It started instantly upon turning the key (normal). Then, it started to idle real low almost like a miss I gave it a little blip of throttle then the check engine flashed and ultimately threw the following codes.
P1300
P0308
P0306
P0302
Cleared the codes and all was fine, till later in the day when leaving the office
It started instantly upon turning the key (normal) but then it started to run like sh$t again, it felt like a miss. Blipped the throttle and then Check engine light flashed multiple times leaving a P0304 code.
I'm stumped...
