Check for vacuum leaks around your manifold. or at the secondary air pump. worst case you could have a failed combination valve it sits on the back of your block hidden down low. try to apply vacuum to it. if it does not hold vacuum at all that will cause that issue.

Car will start sometimes other times i will have to continue to crank the engine it cranks everytime


As it cranks, is there white or black exhaust smoke ?? If yes, the fuel injectors have solid build up on the tips. Normally, a quart bottle of injector cleaner treats 20 gallons. Pour 5 to 7 quarts of fuel injector cleaner. With cold engine (been parked for at least an hour or overnight), while cranking engine, have 2nd person spray starting fluid into air filter. DO NOT PRESS ON GAS PEDAL !!! Let the starting fluid do its job of starting the car. Starting fluid is highly combustible, so its important you don't give any gas while its cranking and 2nd person is spraying into air filter. When engine starts, stop spraying starting fluid and give a little gas. If engine begins to die, immediately spray a little starting fluid again. When engine begins to run, let it run a few minutes to let fuel injector cleaner to do its job (loosen solid carbon build up on tips of fuel injectors).

Not to scare or offend you but it could be many many things. It does help that the check engine light is on, though.
If you can go to a place like Autozone, where they check your check engine light for free, and post what the code was, I can give you a place to start.
I do not mind helping you further with a proper diagnosis procedure either, if you can share your vehicle information.

98 a4 1.8t problem


What is the engine temperature during this? You state that it starts out OK then develops this problem later.

When you have problems starting it is this after running it or after it sits like all night and is dead cold?
