it wont crank over when its hot outside.

As in, nothing happens when the key is turned to "start"?

Alarm system, coded key? Auto/Manual?

it is a auto and it have the factory alarm. as soon a it cools down in the cab it will start up

My 91 used to do that, changing the starter solved the problem.

it have the factory alarm.

If the alarm has a starter interrupt relay in the cab then that may be the problem. Locate the relay and spray it with WD40, that should cool it enough to see if it's your problem. Also important to make sure your battery is in good shape in this heat.

i put a new starter in, changed the starter relay and the neutral safety switch. do you know where i can find that relay for the alarm ?

All those components are outside the cab. Why would you think opening the windows would have an effect on them?

Not me, maybe someone else here can help. If you have a coded key then I'd spray the key tumbler from a can of computer cleaner such as "Dust Off" to see if cooling the sensor will pin point the problem.

after i did all that i found out that if the doors and windows were opeen for awhile that it would start.

it could be a faulty coolant temp sensor-

The engine doesn't even turn over - at least that's what the OP described.
