95 C1500 5.7L hard start warm
Ok, really funny issue here. It's hard to start after it sits out in the hot weather for a while. I can generally drive it after it's running, turn it off and then start it, so long as it doesn't sit 5 minutes. It starts fine in the morning or late in the evening, but if it's been sitting in the sun, it cranks fine, but won't catch. Runs fine otherwise. Changed coolant temperature sensor ontop of the intake manifold. No go. Any ideas?

Won't be able to check for this reason, but when it gives me a lot of trouble.. By the time it does start, I have to rev it or it'll quit. Like it's starting to flood. Turning the key to aux and off repeatedly before trying doesn't seem to make a difference. I can hear the pump prime.
