Longer crank after sitting for a bit.
Hey guys! I went out to start my car this morning after making her sit for over a week (), and it cranked for about about 5 seconds, then finally fired up and ran fine. Can anybody help me diagnose a longer than usual crank time? Battery seemed fine. Turned over at normal speeds, just took longer to fire. The car is procharged, but no other big mods. Any help or input is appreciated.

Re: Longer crank after sitting for a bit.
idk. Mine does the same. Never worried about it. Been like that for years.
But my car will sit for month at a time. I usually floor the gas pedal (this disables the ignition) while turning the engine over to crank it and get oil up in there! Probably a good 8-10 seconds. Then stop for a few seconds and then turn the car on normally.

Re: Longer crank after sitting for a bit.
I remember mine doing that out of the blue even when it hadn't been sitting sometimes, unless it becomes a regular thing I wouldnt worry

Re: Longer crank after sitting for a bit.
next time you let it sit that long cycle the fuel pump a couple times before starting and see if it still has a long crank or not. it could just be a weak check valve allowing the fuel to slowly drain back towards the tank. if it started fine it's probably not anything to worry about. the extra few seconds of cranking helps get the oil moving before the engine starts anyway.

Re: Longer crank after sitting for a bit.
I honestly wouldn't worry,
On this one sometimes it will start up fast and other times it takes a few more cranks. I started pumping the gas pedal a few times and that seems to help it start better. ASh
