i really have no idea where to begin on this. 4kq won't start this morning. the weather is warmer than it has been (around 45F now) and rainy. last night when i left work the car started right up. it was rainy then too. it did this one other time this week but after a few tries it started. the car had been sitting for about 16 hours.
like i said, i have no idea where to even begin to look.

Does the fuel pump prime when you turn the key to "on"?
Check for fuel and spark (pull plug, ground against something).
Could be alot of things (vac leaks, fuel pump relay, coolant temp sensor, grounds, hall sender loose, etc).

The '84 does this sometimes. Nothing else is wrong, just that. I dry out the dist cap, and he fires right up.

Does it appear it gets to TDC and "siezes"? That's a strong arguement for the symptom of plug wires and distributor.
My 84 CGT would start great when it was dry, even at -18. But it could be 85 and raining and it would do as I describes above. Good luck.

i changed the coil wire and distro cap and rotor. fuel pump relay is alright.
car had a hard time starting, when cranking i could hear a little bit of firing from the exhaust but it was sporadic. after some coaxing with the throttle it started but was really rough at idle.
upon a shake down drive i had trouble starting up from stop signs, once it even stalled out. had to keep the rpm's up around 2k to keep from faltering. once the car warmed up the problem went away. completely.
im baffled. one thing i did notice was that the hall sender was loose. the whole section that was supposed to be attatched to the distro was jiggling, not just the plug. on closer inspection all of the wires seemed to be good.
but like i said, the problem disappeared when the car warmed up after about 6 minutes or so...

is to hit the key just enough for the fuel pump to run. The cold start injector will spray, but you won't burn the fuel firing the plugs. If you do this a couple of times, it should start easier.
It soes sound a lot like you have a coolant temp sensor problem, though.
