Question about Nissan Hardbody
Difficult first start
There is a part called a "coolant temperature sensor" This tells the computer what temperature the coolant is at. If the sensor is bad, the computer could read it as the engine is already warm and will create a leaner fuel condition. It takes more fuel to run a cold engine than it does a warm one. The sensor has to be tested with an ohm meter and there is a scale nissan publishes which gives you what the ohm readings should be vs the coolant temperature. On the V-6 it is a mother to get to unles to take apart quite a few things. I have special tools because I race nissan 300Z's which have the same V-6 and if I have to switch one out quickly I can do it in 15 minutes or less, dealing with a hot engine. Anyway that would be the first thing I check. Either the coolant temperature sensor or corrosion on the wires which connect to the the sensor. If you find corrosion and the ohm readings are right, make sure you scrape off the corrosion on the sensor and connector. I hope I'v given you some good insite in solving your problem. Make sure your battery terminals are CLEAN! good luck

Replace the fuel filter and poor a can of Sea Foam motor treatment in a full tank of gas. Sea Foam can be picked up at any part store for $5 to $8 a can. If it still has a problem you may need to replace the spark plugs.

check your fuel filter and changing the plugs couldnt hurt. make sure you use ngk or nd plugs for this. i am a big proponent of manufacturer parts. they were designed for the vehicle.
