Default wont start cold

hey everyone I have an s-10 that wont start when it is cold, if i spray some carb clean in the intake tube it usually starts and runs rough for a little bit. once its running i can shut it off and turn it back on no problems. i dont know if it matters but the temp gauge only goes up to about 1/8 inch off cold which isnt far at all. I dont know if that is related *or* not but im thinking the starting problem is fuel related. It has a new regualter and filter on it. it also feels weak on power going like 50 you have to kick it down to go any faster. weak pump? electrical? I did a basic tune up ie: plugs wires filter and both coils. any help? and ideas what else to look at?

what year is your truck.
is it fuel injected?
If it is change your coolant temp. sensor.
that should fix it.

Sounds like a fuel pump to me....check the pressure when you get it running

It would help if you gave the year of the truck and the type of engine. Is it all the time? First start of the day? or just when it is cold outside?
