Extended Crank Time When Cold
Good Afternoon:
I have a 1998 DI that was purchased two months ago. I have noticed that when the engine is hot and the outside temp is above 85-90 degrees, it seems hard to start and has to "clear out" after it does. I replaced the Fuel Temp Sensor...still havn't determined whether this helped,or not.
Today, the vehicle had been sitting for about 1.5 days and I had to attempt to start it several times...which it finally did?
I do not have any codes, and the vehicle seems like I'm driving into a very strong headwind when pulling hills, or with a small load of about 1500 pounds, or so?
I have not checked fuel pressure...any thoughts?
Coil pack (plugs are new Bosch Platinums and new wires)
Fuel Pressure Regulator
Fuel Pump
Any guesses?
Thanks!

Sounds like your fuel pump cannot supply the demand.
When the truck is idling the pressure gets built up, but once you increase the fuel demand the pump cannot supply enough.
The 24psi when cold, how long did it sit? Over night? A week?
After sitting for a week or more I would expect a lower number before starting the engine, but not from overnight.
