Mitsubishi lancer 2003 starts when cold - when hot starts and stops

SOURCE: 2003 Mitsubishi Eclipse GS blows cold air in heat mode.

ok here we go and you aren't going to believe it...
I replaced the thermostat step one

I noticed that I had a small leak at the engine side of upper hose fixed that by taking it off and cleaning it and putting the hose back on Step two

then while refilling the reservoir with coolant i found that the hose that was supposed to be in the fluid was curled up on top and not sticking down in the fluid where it should be.
played with the hose until i got it to fall down in the reservoir where it should be Step 3

I started the car with the radiator cap off and let it run until it got to normal operating temp. and keep filling the radiator with fluid until the level stayed constant. Then put the cap back on and test drove. Everything worked fine haven't had that much heat in awhile and it kept blowing hot even when i stopped and let it idle for ten min.during test drive. Checked reservoir when I got home and had to add a small amount of coolant but not much.

I really think that the hose in the reservoir not being in the right place and pulling air into the system instead of coolant is the real culprit of this drama, but i replaced the thermostat to be safe.

SOURCE: I have no heat in my 2003 Mitsubishi Lancer. When

The cable that pulls the cool/heat switch on the a/c gets weak and it doesnt allow the dial to switch over to heat. You can see that cable and the way its supposed to work on the right side of the gas pedal over it. I usually just use my foot to push that switch over to heat and reach with and pull on it with my right hand to cool.

Fuel pump

Testimonial: "It's the fuel pump indeed. Also the gas tank found to be very dirty. The fuel pump was replaced, fuel system cleaned, now the car runs perfectly."

very poss it could be crank sensor ,broken wire ? timing belt? advise installing scan tool that reads live data check eng rpm on scan tool see if shows eng rpm while cranking , poss remove upper timing belt cover make sure is turning and not damaged, poss computer related problem or power to eng systems would have to check for power at fuel injs and check for ground pulse with logic probe or led test light if crank sensor ok also check for spark at plugs with special plug tester and check codes first
