Thought I’d ck before taking in or begin anything in depth. I realize when cold with thick oil etc can add to the problem but not like this. Thought it was a weak battery so rather than texting with a load tester I just replaced it. No change. 25 deg morning it will crank for up to 4 plus seconds it seems. Summer months or when warm no issues. Fuel filter? Injectors?
Tks for any help.

hook up a pressure gauge to the fuel rail cycle the car on and wait like 3-4 seconds for pump to prime then turn off...dont start the car....and see if it hold pressure...could be a fuel pressure regulator going bad and bleeding down...

Slow crank vs long crank before fire is two different things. Which is it ?
You have a scanner ? Ist thing i check is letting it sit over night and before running ck coolant temp vs air temp. If iff mire than 10-15f degrees, it’s coolant temp tine.
Also, if you user super for gas, see with gas station when their super tank was filled. Summer blend has tough time firing up in winter.

Thanks SB. I have an older scanner that’s not compatible with so might have to run it in and get the ecu cked out. It’s all stock and runs great with the exception of starting when cold. Seems like the injectors aren’t getting a correct signal or lack of pressure. Have no clue! That’s why I like my 76 Chevy truck. 😂




Bad things happen when your fuel tanks are 20 feet from the lake and under the water table.
