Hard start after 3 week sit.

[dhe]

I KNOW my tracker - 2001, likes to be driven once a week. I've let it sit before more than two weeks, and had a heck of a time getting it started.

Well, with the covid, I did it again. I go to turn over and instead of starting instantly, I get kind of a wheezing sound.

I WAS able to get it going, by using a trick I read here, one pump of the accelerator, turn the key and hold the accelerator half way down.

-- Once it turned over, it idled a little rough, so I gave it some gas, after running it 30 miles, all is good again. Just kind of curious as to guesses as to what this might be? I'm guess something with a vacuum or fuel pump?

I do always turn the key to the first click and wait at least 45 seconds for all sounds to stop, before trying to turn it over.

Thanks for any guesses. Wouldn't it be nice if fixing the problem was as easy as replacing the gas cap?

Thanks,
