hard starting when left sitting over night.

hey guys, this just started happening the other night.

92 f150 5.0

has new fuel pumps
has a new computer,
new plugs,
wires,


my mom said when she came home from work it would not start, just cranked and cranked, then it started up and ran fine,

i just went out there and tryed to start it,

just cranked and cranked trying to start, then it caught and started, but it was boggy for a couple of sec and backfire through the throttle body,

now its running fine,

any one got any idea what could be causing this.


i do have a code about the coolant temp sensor

My guess would be the coolant temp sensor isn't reading right and flooding the motor out.

how long should there be pressure in the fuel rails?

i let the truck sit for the day , and before i went to try to start it i checked for pressure in the fuel rail and not one drop of gas came out the bleeder valve.

turn the key on and off about 6 times and she started right up but she was a little rough but smooth out really quick.

I'd start by getting a fuel pressure gauge, and seeing what your fuel pressure is actually doing.
