My Daughter recently bought this van . It has157,000 plus miles.
When it is cold it is hard to start. Cranks over good .starts better
after it warms up. Needs other work as well brakes oil change etc
Not sure why it is hard to start when cold?

Could be two easy fixes - try cleaning the intake manifold and/or injectors and test the battery for charge - it may be weak and thus making it hard to start the car. It might also be a vacuum leak if any of the hoses are cracked - once they warm up the swell and close small leaks. Other fixes include replacing the spark plugs and wires, checking the distributor cap, try this link:

it might need a tune up or ur starter might be going out

could be the cold start injector.
