<!-- from fixya rte -->Truck cranks when cold will not stay running - 1999 Chevrolet K1500

no year car told. wow. "I'm having No start fuel problem" why does the first line contradict others?
NO CRANK
cranks good but will not start
cranks good but starts and stalls.
cranks and runs but RPM races to high(too high RPM not told)
normal cold is about 1500 RPM but at -39F RPM will go higher that is how EFI works here. even 2500 is possible say in Alaska.USA.
-80f there. possible (record temp low)
fuel hates to vaporize cold and the colder it is the worse that is
and the PCM knows all that for over 43 years of EFI tech.
is this your first car
or first car cold outside
or first ever Klondyke cold snap?

Hot and Cold: When your Engine is Hard to Start

What is your year--make--model--engine size? On a cold engine, you can try cycling the key on and off several times before you crank it, see if it helps? By doing that, your priming the fuel system.

Usually electric fuel pumps are in the gas tank, but, without year--make--model, I can't look up any info.

the automatic choke is working and thats why it does that because the car hasn't been cranked and its cold natured. this is normal for older cars and trucks with regular carbs.

Check the crank case sensor

immobilizer , crank and cam position sensors are contenders for the problem

a bad engine coolant temperature sensor will cause cold no start conditions.your coolant sensor main sensor during cold start condition because when engine coolant cold PCM will cause rich fuel mixture for cold start up when engine coolant and oxygen sensor warms up cause engine goo in close loop lean mixture.but coolant sensor is the main information sensor if bad it will cause many problems.

-Possibly the battery is not strong enough to crank. Try high
CCA battery. For example now the one you have has CCA 750
How about change to the maximum that they carry.

Good luck

probably it is your crank shaft sensor when it is cold it expands and when it gets hot it is not making contact

Have him remove & clean th IAC/AIS motor on the throttle body, and the port it came out of , as well as clean inside of throttle body if he hasn't done so already. Check and clean connections before re-assembling. Shouldn't take any longer than 1/2 hr or so.
