77 280Z problem cranking when hot

Hot starts fail.
ever do a tune up, spark parts? filters?
does it start backup if you WOT crank it
WOT -= wide open throttle or as some say flooring the gas pedal
and crank it. (the trick is it cuts fuel fully to clear the flood)
this clears flooding, (on all EFI cars made)
or test #1 , crank with just 5% added throttle this trick
adds air to hide bad IAC valve. and engine starts. (tricks/skills/ASE magic)\what eva.
but may stall if you lift the right foot, does it? hot?
test 3. will it start up with sprayed, instant start in a can?
hot? at air cleaner intake,
run for 3seconds and stall.
if yes fueling is wrong, (as in none)
if NO, spark is dead or weak

It will work fine. The CCA is a rating of how much power that the battery is capable of delivering at once and as the name suggests, cold cranking amps, is needed more in cold temperatures. As long as you are not in the arctic, it should be fine for a couple of days.

post is good and clear, no engine size stated.>>>
can you jump start it?//
this simple check proves battery is good /bad or just discharged.
yes, jumps and runs. (ever clean the battery lugs ever?
if it jumps the battery is bad/or disharged, so charge it.
no, wont jump cold
bad starter. or funky key line.

1: i hot wire these starters,
cranks ok, good starter.
no crank bad key line
if key line is dead, well wiggle the key and wiggle the gear shifter.
is car a A/T or M/T.
if M/T wiggle the clutch.
now you have your answer, an why. how is a differnt horse.

seems, means nuttn. (no jumper cables,?????)
only a volt meter works, seems is zero .
a rested charged battery and (warm temps) is 12.6vdc.
you crank it, (not in Klondike?) and battery holds above 11v. cranking
does it? if not the battery is bad, or not charged.
jumper cables to other car fix it?
barrowed battery from wifes good car fix it?
no,
no.?
ok are battery cables cleaned, the lugs.
yes.
you hot wire the starter (keys in pocket)
starter works (engine dont start for safety here)
it fails to crank, starter is bad.
it cranks, that means the key line is dead.

if key line fails, did you wiggle the shifter cranking, , do so.
if that starts car the PRNDL switch is bad. on trans side.

Don't assume your battery is fine. Just because it measures 12-13 volts doesn't make it fine. You need to test it under load and see if it holds 12-13 volts under load. If you don't have the instruments to do that, try jump starting the car with cables connected to another running car. If it starts normally, your battery is bad. If it continues to "click", you have a dirty connection in the battery wire circuit. Remove, clean, and replace the terminal connections.

Its a hot start issue.

Can be related to low fuel pressure or problem with crank sensor.

Also it can be weak battery or starter.

But possibilities are to be inspected to confirm what exactly it is.------

Does it crank, yet not start? Or does it not even crank?
If it cranks and doesn't start, you could have a leaky fuel injector. Pull the plugs when this happens, and check them for fuel saturation.

If it doesn't even crank, it could be an intermittent starter.

If crank sensor is completely dead your car won't be start any more, some time crank sensor get faulty when it get hot only then when car cold start fine.

your battery might not have enough cold cranking amps to get your motor running. consider upgrading to a stronger battery. but first take your current battery to a auto parts store and have a load test done on it.
