This symptom is usually caused by an issue with the evap system.It solely depends on vehicle type,but this system usually includes the gas cap,various hoses,a rollover/ vent valve,carbon canister and a purge valve.This system basically prevents fuel vapors from escaping to the atmosphere and these vapors are instead sent from the fuel tank to a carbon canister where they're stored until the engine uses a purge valve and engine vacuum to draw these vapors directly into the engine usually through a intake manifold vacuum fitting where these vapors are then burned just like raw fuel is.So it's part of the emissions system. When these vapors aren't allowed to escape from the fuel tank via the system components I listed,it basically creates a vapor lock condition and the symptoms you're having.It could be something as simple as a faulty gas cap or leaking/ clogged evap system vacuum hose or possibly a bad vent valve or purge valve.Most of these components are easy to access and replace with the exception of the vent valve which is located in the top of the fuel tank,which would obviously require you to either drop or,hopefully,just lower the fuel tank to access/replace the valve.If a check engine light comes/stays on when the symptoms are present,a code would possibly be stored which you could verify with a scanner.If you don't own one,AutoZone/Oreillys/Etc will scan the vehicle for you also if you don't own one & it's free.

first will be starter try to tap starter if start is a starter problem.sometimes charged is not good is weak.try to boost.Battery connection.

it sound to me like your temperature blend door actuator is bad

Hi, if the code was P0455, there are other possible reasons. The computer fuel tank pressure sensor has detected a leak which could also be in the vapor canister, or the hose from the canister to the purge valve, or the purge valve itself may be leaking. Please inspect the system for these leaks. I may be able to provide some pics of these parts if you tell me your model, year, and engine info.

Evaporative Emission Control System Leak Detected (no purge flow or large leak)
What does that mean? This indicates a fuel vapor leak or lack of purge flow in the EVAP control system. It means a large leak has been detected. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
Symptoms You likely won't notice any drivability problems.
Causes A code p0455 most likely means one or more of the following has happened:

• A loose or improperly affixed gas cap
• A non-conforming gas cap (i.e. not factory/original brand)
• Other leak or damaged piece in EVAP system

Possible Solutions With a p0455, the most common repair is to:

• Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
• Otherwise, replace the gas cap, and/or
• Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary

sounds like an electical fault maybe car alarm or wiring going to distributor

P0442 OBD-II Trouble Code - Evaporative Emission Control System Leak Detected (small leak)

What does that mean?
This indicates a fuel vapor leak in the EVAP control system. It means a very small leak has been detected. In fact, the leak can be from a hole as small as 0.04" in diameter. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.


Symptoms
You likely won't notice any drivability problems.


Causes
A code P0442 most likely means one or more of the following has happened:
* A loose or improperly affixed gas cap
* A non-conforming gas cap (i.e. not factory/original brand)
* A small leak/hole in a fuel vapor hose/tube
* Other small leak in EVAP system
* Faulty vent o-ring seal


Possible Solutions
With a P0442, the most common repair is to:
* Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
* Otherwise, replace the gas cap, or
* Inspect the EVAP system for cuts/holes in tubes/hoses

Hope this help, good luck.

check volts at starter while keying up.
try jumping starter solenoid out.
