1993 Nissan Pickup Starts in Morning. wont start after that. baffled!

Could easily be a CTS (coolant temp sensor) causing the problem. Nissans' seem to have a problem with the connectors, so take a good look at that. If you have a scanner, you can see what the computer is seeing (engine temp). When the CTS goes bad, they usually default to "cold". If the computer is seeing that the engine temp is
-41F, it's gonna dump fuel, thinking the engine is really cold. A cold engine can handle (and needs) the excess fuel. A warm engine is going to 'flood'. In a situation with a flooded engine, hold the throttle to the floor while cranking until the engine starts running, backing off the throttle as it begins running so as not to over-rev.

loren i just want to thank you! that is EXACTLY what it was. i bought the part the next day. put it in my truck and now it runs perfectly. starts up over and over again. tested it about 20+ times cold and hot and no problems. whats even funnier is i had the auto parts store and a few mechanics try to tell me it was something else. but i figured what the hell its only a $20 dollar part. so i bought it and i gotta say man..thank you so so much. you have no idea how much it means to me. you basically just saved me like $1000 dollars. ( i was gonna give up and buy a used car for the winter)

thanks a million.
