def CSI like he said... its leaking a small amount of fuel like dripping so overnight its flooded and in the morning it takes a few cranks to clear out.... not the biggest problem but u can fix it easy! most cars start even without csi

Look at part 23260 in the diagram in the attached link. That's the cold start injector.

Crank sensors either work or they don't. You either need a CSI or your fuel pressure is low for some reason.

It could also be one of the regular injectors sticking open.

If it is an injector leaking into the intake, what you can do when this happens, is when cranking, if it won't start, press and hold the gas pedal. That will allow more air in to get the mixture right for it to fire.

My daily (90' 4afe) started doing this to me recently and I haven't been able to spend much time on it but it takes two or three cycles of the key to start it from cold no matter the outside air temp. So far I quickly replaced the cold start injector without any change.

My car's cooling fans also come on when I turn the key on,(I have A/C in my car but this may or may not have anything to do with the starting problem), from a cold start so this leads my to believe that it may be a bad coolant temp sensor or bad wiring along the way so the ecu thinks the car is warm already thus turning my fans on from a cold start and not sending a signal to the cold start injector. When I have more time I will report what I find.

i definately agree with that. but which sensor is which since ther is two? i always assumes the forward one was for cold-starts and the other is for gauge/running
