1996 C2500 Suburban 7.4, hard starting and has OBDII code of P174
Truck is hard to start, especially in cold weather. It sometimes hesitates from a stop when trying to accellerate. Has service engine soon light on and the code is P0174. Can you offer any solutions or tell me what to check ?

This really sounds like a problem with your battery. I know you said you checked it, but is it really putting out the appropriate voltage (12.66 volts) and CCAs? Even draining the battery once can damage it (especially in cold weather), and cold weather reduces the CCAs a battery can put out. A weak battery can cause those codes. When the vehicle hesitates to start, does that typically happen on colder mornings or after the car sat for longer periods of time? I would double-check your battery. If it's the original, it's near its end of life anyway.
Check your battery for proper volts (12.6). Sometimes the cold weather will bring a battery down. Also check the Starter Relay, again cold weather will make it stick causing it not to start. Those are the biggest problems with a car not starting in the cold weather unless you have something else going on then your starter and your ignition needs to be checked.
