I want to know if what I am about to describe here sound like I have air in my fuel system.
It has been hot here in Oklahoma with 100 degree weather. It takes 4 or 5 attempts on the starter for a couple of seconds each before my 2GM20F picks up. Once running, it sounds good with plenty of power. If the weather were cooler, it would be a little more difficult to start.
While the engine is trying to start, there is no excessive smoking. Once the engine starts, is runs nicely, smoothly, with power and no visible smoke at all; there is no excessive smells either. It does seem to run at a faster idle than my friends 2GM20F. If I try to start the engine within a couple of hours of it having run, it will start right up. If left over night it takes several attempts.
Does that sound like an issue with air in the fuel system? Or does something else sound more likely?
I am really interested in knowing if what I have described closely approaches what one would experience if air were in or around the injectors. Or said another way, how would the engine perform if there were a little air in the system and could it cause the symptoms I have described?
A follow up to that is this question: If there were a little air in the system and the engine starts and runs nicely once started, then wouldn't the air soon be removed and not be an issue assuming that there is no small leak or point of subsequent air intrusion? Let's say that there is a little air in the system but the engine starts; then, if once the engine starts and there is no re-introduction of air into the system, will the engine have cleansed itself of the original air?
Sorry to belabor this so. Experience is such a better teacher but, good instruction softens the consequence and improves the experience.
Thank you for your reply,
