I have a 97 corolla, when I first start it in the morning it starts fairly easy, but when it warms up and im running errands around town, it cranks longer before it wants to restart, and its getting worse, does this sound like a cran sensor going bad or possible vapor locking?

check whether you do have a problem with your cam or crank sensor. Or the fuel pump whether when it gets warm stop working,(loosing the pressure ) These things you do need a specialist to check the sensors and the fuel pump.

You need to test the fuel pressure at the service port to see what the pressure is in the fuel system. Should have approx. 50-60psi on this system. you either have injectors that are bleeding down terribly (unlikely), a bad fuel pressure regulator (fairly likely), or bad check valve in fuel pump ((also fairly likely).

Find a new auto TECHNICIAN, not a joe blow shade-tree guy.

Would you give us more informations like:
-The car start and run about... and shut off.
-The car can't strt at all.
-How it did after start.

test the crank sensor

replace crank sensor. It gets hot and stops working.

replace fuel filter.check fuel pressure.

try this put some STP gas treatment and checkout your fuel filter which is under the car in the frame on the passenager side and checkout the drive belt if all of this fails have the alternator tested and you would know if its the alternator cause driving at night most of the lights would stay on the dash cause the car would be running off the battery and most of the repair you are having now are easy check out this website it www.autozone.com if they do they will have diagrams and pictures showing you how to repair your car and check on parts and prices at the same time there is www.taurusclub.com i hope i have been some help to you Michigan Man.

does it have a cold start injector seperate from the other injectors usually on the upper intake somewhere with a fuel line going to it
