What causes a hard start when cold, starts fine?
To get to the root of it, an internal combustion engine needs 3 things to run: air, spark, and fuel. Air is going to come through your throttle body by way of the filter. Clogged filters don’t typically cause hard cold starts and bad throttle bodies cause a lot of other problems, so I think you’re in the clear here.
Why does my Car start hard when it’s cold?
The pressure regulator (relief) valve may have allowed fuel in the line to drain back into the tank. Which when starting the engine would require a longer crank time to get the fuel system back up to pressure. Long as it does not take more than 15 seconds for the engine to start; there is no problem with the car.
Why is my Bug hard to start when engine warm / hot?
A intake leak will normally cause a rough idle or even stalling Hot or cold but a little worse when hot. If the engine runs and idles fine after you get it started tells me that something else is going on. Just remember you are up there and we are down here and don’t have a “hands on” deal.
Why does my bike start cold or hot?
On cold starts, the engine usually fires right up, but after reaching operating temperatures or when on the hot side, I occasionally have a hard time getting the bike to start. The dealer has already replaced the starter, because it sounded like a thrashing machine.

Can a bad throttle body cause a cold start?
Clogged filters don’t typically cause hard cold starts and bad throttle bodies cause a lot of other problems, so I think you’re in the clear here. Spark goes to the plugs by way of the coil packs by way of the battery and alternator.
Why is my cold start valve leaking so much?
He said its my cold start valve and that alot of 22re engines have this problem. He told me that the valve would get weak over time and start to leak constantly because even when you shut the engine off you still have 40psi of fuel pressure in the lines. That combined with a leaking valve = starting problems and flooding out.
