Hesitating to start
Alright every now and then (3-4 weeks) ill hope in my car and drive somewhere. never more than 10 miles. park it. go into watever building i am going into and come back out and try and start the car. The times this has happened the car has sat for 15-40 min. So i hop in the car, turn the key, and i know it primes the lines, i hear it and we have directly wired the fuel pump ourselves, (brand new pump). and when i turn the key, the starter just goes and goes but the car takes a good 3 seconds of turning over to start. its the weirdest thing. then i may go down the street get out, go get a hamburger and come out and it may not do it. it did it the weekend before memorial day after it was hot, then sat for ~20 min. then tonight after sitting for ~30 min. any guesses on what would cause it to hesitate to start? is the engine mods??

My wifes Chrysler does that and from googling it, it appears to have something to do with the purge solenoid on her car.
If you have a scan gauge that will read fuel pressure, make sure it doesn't drop to zero after the pump primes. It should stay at 40. Mine slowly bleeds down at about 1psi per 5-10 seconds.
You could have leaky injectors

My wifes car will sometimes do it from a cold start too, which really makes it hard to diagnose. Mostly it's a hot start problem though.

That was a bit harder to follow. Are u saying that my injectors leak and drip into the cylinders sometimes and when i try and start the car THOSE TIMES, that the cylinders are "flooded" which causes it to just turn over and over for 3-4 seconds?

Yes, you could have too much fuel and not enough air = no combustion.
